FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with blood tests is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about blood tests, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to blood tests, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on blood tests. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to blood tests, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on blood tests. The Editors

CHAPTER 1. STUDIES ON BLOOD TESTS Overview In this chapter, we will show you how to locate peer-reviewed references and studies on blood tests.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and blood tests, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “blood tests” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •

[email protected]. Summary: Acute pancreatitis (inflammation of the pancreas) can happen to anyone, anytime. However, repeated episodes put the patient at risk for chronic pancreatitis and pancreatic cancer, so it is important to learn about the risk factors and symptoms of these diseases. This article reviews the presenting symptoms of pancreatitis, the anatomy and physiology of the healthy pancreas, treatment options, and the risk factors for pancreatic cancer. The most common cause of acute pancreatitis is gallstones that get

caught at the opening into the small intestine. Excessive alcohol use is another common cause of the disease. Diagnosis can include blood tests, an abdominal CT (computed tomography) scan, and endoscopic ultrasound. Treatment for acute pancreatitis is usually relatively low tech, featuring hydration (adequate fluids), pain management, and nutrition support (intravenous). During an episode of acute pancreatitis, which can last days or even a week, patients usually do not eat any food at all initially. Clear liquids and then low fat foods are added gradually as symptoms improve. When gallstones cause pancreatitis, surgery to remove them is usually necessary. For those who already have chronic pancreatitis or are at risk for developing it, a healthy lifestyle and positive attitude are essential. Many people with pancreatitis find that a low fat diet helps reduce the severity of acute episodes and also slows the progression of the chronic disease. One sidebar offers a description of hereditary pancreatitis, which is a rare condition. The final section of the article discusses pancreatic cancer, noting that both chronic and hereditary pancreatitis put people at higher risk for developing pancreatic cancer. Appended to the article is a list of websites for readers who want to locate additional information about pancreatitis. 2 figures. •
Gastrointestinal Safety and Tolerance of Ibuprofen at Maximum Over-the-Counter Dose Source: Alimentary Pharmacology and Therapeutics. 13(7): 897-906. July 1999.

[email protected]. Website: www.blackwell-science.com. Summary: Determining nonsteroidal antiinflammatory drug (NSAID) gastrointestinal toxicity has largely depended on retrospective epidemiologic studies that demonstrate that lower doses of NSAIDs pose a lower risk of gastrointestinal toxicity. Ibuprofen, a proprionic acid NSAID has, in most such studies, exhibited a favorable profile in terms of gastrointestinal bleeding. This article reports on a study that prospectively evaluated the gastrointestinal tolerability, as compared to placebo, of the maximum nonprescription dose and duration of ibuprofen use in healthy subjects representative of a nonprescription analgesic user population. Gastrointestinal adverse experiences were similar in the placebo and ibuprofen groups (67 out of 413 patients, 16 percent with placebo versus 161 out of 833 patients, 19 percent with ibuprofen). There was no difference between the two groups in the proportion discontinuing due to a gastrointestinal event. Gastrointestinal adverse experiences reported by more than 1 percent of subjects were dyspepsia (heartburn), abdominal pain, nausea, diarrhea, flatulence (gas), and constipation. Seventeen (1.4 percent) subjects had positive occult blood tests; their frequency was comparable between treatments. The authors conclude that, when used as directed to treat episodic pain, nonprescription ibuprofen at the maximum dose (1200 mg per day for 10 days) is well tolerated. 4 tables. 22 references.

search for non invasive diagnostic tests. This article reports on a study undertaken to evaluate the efficacy of a new enzyme immunoassay designed to detect H. pylori antigens in stools (HpSA), before and after eradication therapy. HpSA was performed on stool samples collected from 268 patients whose H. pylori status was defined on the basis of concordant results for the 13C urea breath test, rapid urease test, and histology. The H. pylori positive patients were treated with a 1 week triple therapy to eradicate the infection. One (T30) and 3 months (T90) after the end of therapy. 13C urea breath tests and HpSA were repeated in the treated patients. The overall diagnostic accuracy of HpSA at T30 (83 percent) was significantly lower in comparison to the values obtained at baseline (94 percent) and at T90 (97 percent). No significant difference was found between the diagnostic accuracy of HpSA at baseline and at T90. The authors conclude that these data suggest HpSA provides a low diagnostic accuracy when used shortly after treatment. It needs a longer period of followup (8 to 12 weeks) to reach a reliability comparable to the 13C urea breath test. In regards to the issue of cost effectiveness, the kit and technical support for the HpSA is approximately $27 per test; this cost is higher than serology (blood tests), which cannot be reliably used in the post treatment phase, but lower than the 13C urea breath test, at approximately $50. The authors believe that HpSA can be reasonably included among non invasive tests as an accurate and cost effective alternative to the 13C urea breath test for the pretreatment diagnosis of H. pylori infection; for the assessment of eradication, it can be highly reliable, provided that it is performed 3 months after the end of treatment. 5 figures. 25 references. •
Noninvasive Monitoring of Patients with Chronic Hepatitis C Source: Hepatology. 36(5 Supplemental 1): S57-S64. November 2002. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: Hepatic (liver) fibrosis is the main determinant of clinical outcomes of chronic hepatitis C. Liver biopsy is frequently considered the gold standard for assessing hepatic fibrosis. However, liver biopsy is associated with sampling error, interobserver variability, and potential complications. This article considers the options for noninvasive monitoring of and assessing disease severity in patients with chronic hepatitis C. Clinical examination is unreliable in differentiating different stages of compensated liver disease. Among the routine laboratory tests, decreased platelet count, increase in the ratio of aspartate to alanine aminotransferase (AST ALT), and prolonged prothrombin time are the earliest indicators of cirrhosis and portal hypertension. Individual serum fibrosis markers (blood tests) have limited accuracy in predicting hepatic fibrosis. Indices composed of a panel of markers correlate better with histological fibrosis, but their reliability requires further validation. Currently, noninvasive monitoring of patients with chronic hepatitis C relies on clinical evaluation, routine laboratory tests, and ultrasound and endoscopic surveillance in patients with cirrhosis. Initial evaluation should focus on assessment of activity and stage of liver disease for prognosis and decisions regarding treatment, and to rule out coinfections and other causes of liver disease. Subsequent follow up should focus on detection of liver disease progression and the need for treatment. The frequency of monitoring and the tests used will depend on the patient's age, stage of liver disease, and comorbid conditions. The authors conclude that there is an urgent need to develop and validate noninvasive tests that can accurately reflect the full spectrum of hepatic inflammation and fibrosis in chronic hepatitis C. 5 tables. 37 references.

Hemorrhoids and More: Common Causes of Blood in the Stool Source: Digestive Health and Nutrition. 3(4): 24-26. July-August 2001. Contact: Available from American Gastroenterological Association. 7910 Woodmont Avenue, 7th Floor, Bethesda, MD 20814. (877) DHN-4YOU or (301) 654-2055, ext. 650. Email:
[email protected]. Summary: Most rectal bleeding is caused by hemorrhoids, which usually can be simply and effectively treated. This article reviews the many other conditions, including some serious disorders, that can cause blood in the stool. The author reminds readers that bleeding from any part of the nearly 40 foot long digestive tract can cause blood in the stool. Accurate and timely diagnostic tests are important to determine the cause of any bleeding. Bleeding higher up in the gut, from the esophagus or stomach, can result in stools with a black, tarry appearance. Bleeding from the lower end, such as the colon, or in large amounts, can appear as pure blood, blood clots, or as blood mixed with or streaking the stool. Another kind of blood, occult or hidden blood, may not be visible at all. A number of prescription and over the counter (OTC) medications can cause bleeding in the stomach and small intestine. The blood thinning drug warfarin also can induce bleeding in the intestine, as can some antibiotics. Other causes of bleeding can include ulcers, gastritis (inflammation of the stomach lining), ulcerative colitis, Crohn's disease, polyps (small growths inside the intestine), diverticular disease, abnormalities in the blood vessels (vascular anomalies), anal fissures (tears) and fistulas (abnormal openings between the anal canal and other organs, such as the bladder), and abscesses (pockets of infection. The author reiterates the importance of timely diagnosis, including a thorough patient history and evaluation of symptoms. Diagnostic tests can include blood tests, digital rectal examination, endoscopy, colonoscopy, sigmoidoscopy, fecal occult blood test, barium x rays, angiography (x rays of blood vessels), and nuclear scanning. Treatment depends on the source and extent of the bleeding.

Effect of HFE Genotypes on Measurements of Iron Overload in Patients Attending a Health Appraisal Clinic Source: Annals of Internal Medicine. 133(5): 329-337. September 5, 2000. Contact: Available from American College of Physicians. American Society of Internal Medicine. 190 North Independence Mall West, Philadelphia, PA 19106-1572. Website: www.acponline.org. Summary: The gene that causes most cases of hereditary hemochromatosis (HH, an inherited propensity to absorb excess iron) is designated HFE. Three mutations exist at this locus at a relatively high gene frequency. This article reports on a study undertaken to determine the gene frequency of the three HFE mutations and to relate genotypes to various clinical and laboratory variables. The observational study included 10,198 adults who registered for health appraisal and consented to DNA examination for hemochromatosis. Consenting patients were slightly older and had attained a slightly higher educational level than nonconsenting patients. In white participants, the gene frequencies were 0.063 for the C282Y mutation, 0.152 for the H63D mutation, and 0.016 for the S65C mutation. Gene frequencies were lower in other ethnic groups. In participants with HFE mutations, blood tests showed that the average serum transferrin saturation and ferritin levels were slightly increased, as were mean hemoglobin levels and mean corpuscular volume. The prevalence of iron deficiency anemia was lower in women who carried HFE mutations. The authors conclude that screening for transferrin saturation and ferritin levels does not detect all homozygotes for the major hemochromatosis mutation. The authors briefly discuss the ongoing question of

Progressive Sensorineural Hearing Loss, Subjective Tinnitus and Vertigo Caused By Elevated Blood Lipids Source: ENT. Ear, Nose, and Throat Journal. 76(10): 716-730. October 1997. Summary: The otologist frequently sees patients with progressive sensorineural hearing loss, subjective aural tinnitus, and vertigo with no apparent cause. Elevated blood lipids may be a cause of inner ear malfunction on a biochemical basis. This article reports on a study undertaken to establish the true incidence of this condition. All new patients (n = 4,251) seen during an eight-year period were evaluated; of these, 2,332 patients had complaints of inner ear disease. All the patients had a complete neurotologic examination, appropriate audiometric and vestibular studies and imaging, and blood tests including lipid phenotype studies. Hyperlipoproteinemia was found in 120 patients (5.1 percent). Most patients were found to be overweight and had additional coexisting conditions such as diabetes mellitus. Treatment with vasodilators and a 500 calorie, high-protein, low-carbohydrate diet yielded improvement of symptoms in 83 percent of patients within five months of initiation of treatment. The authors include three detailed case studies. The authors conclude that the cause-and-effect relationship between hyperlipoproteinemia and dysfunction of the inner ear is indisputable. 6 figures. 14 references. (AA-M).

[email protected]. Website: www.blackwell-science.com. Summary: There are two general ways in which a diagnosis of infection by Helicobacter pylori can be made: by using either an invasive or a noninvasive procedure. This article reviews the current thinking on the use of these tests. The invasive procedures involve an endoscopy and biopsy. A biopsy is essential because often the mucosa may appear macroscopically normal but nevertheless be inflamed. A biopsy is obtained by histological examination, culture, polymerase chain reaction (PCR), or detection of the presence of urease activity in biopsy material. The noninvasive tests that can be used to diagnose the infection are serology (blood tests); detection of labeled metabolic products of urea hydrolysis in the breath, the urine, or the blood; and detection of H. pylori antigen in a stool specimen. The authors conclude that at present, no single test can be relied upon to detect definitely colonization by H. pylori, and a combination of two is recommended if this is feasible. The choice of the test to be used is not straightforward and may vary according to the clinical condition and local expertise. 8 tables. 95 references.

Blood Tests
Summary: This article examines the blood bank industry's initial response to the AIDS crisis in the early 1980's. Following a trail of events, meetings, and documentations of transfusion-associated AIDS cases, the author concludes that the blood bankers acted too slowly in alerting the public about contamination of the blood supply with the AIDS virus and in responding to protect the safety of that supply. She charges that the not-forprofit blood centers mishandled the AIDS crisis in the beginning by: 1) refusing initially to accept evidence that the AIDS virus could be transmitted by transfusion; 2) delaying the implementation of active screening procedures designed to discourage blood donations from people at high risk for AIDS; 3) resisting the use of surrogate blood tests that could be used as stopgap measures to reduce risk until a more specific AIDS screening test became available; and 4) making exaggerated claims about the antibody test's ability to identify AIDS-contaminated blood. The author traces the history and growth of the blood business, particularly the American Red Cross, focusing on the profit margins and competitive nature of the industry. •

[email protected]. Summary: This article helps readers protect their livers from potentially harmful medications, vitamins and supplements. Written particularly for people with chronic liver diseases, such as viral hepatitis, cirrhosis (liver scarring), or other liver diseases, the article reviews how the liver works and why it is vulnerable to drug complications. Many seemingly innocuous products can cause significant injury if the liver is not able to properly process them. For example, liver patients and people with alcohol abuse can only tolerate the common medication, acetaminophen (Tylenol) at lower doses. And while acetaminophen can be tolerated in small doses in liver patients, ibuprofen products (Advil, Motrin) as well as other nonsteroidal antiinflammatory drugs (NSAIDs) should be avoided by those with hepatitis and cirrhosis. Some herbal supplements and vitamins also can damage the liver if taken in higher than recommended amounts or if there is an existing liver disease. When potentially hepatotoxic (liver damaging) medications are required to treat a patient's disease, the patient should consult with their physician about performing regular blood tests to monitor liver enzyme levels. One sidebar lists products containing acetaminophen and NSAIDs. The article concludes with a list of five websites for readers who wish to obtain more information. 1 table.

Bacterial Osteomyelitis in Adults: Evolving Considerations in Diagnosis and Treatment Source: American Journal of Medicine. 101:550-561. November 1996. Summary: This article presents pathophysiologic and clinical aspects of an adult patient with bacterial osteomyelitis and considerations for its diagnosis and treatment. Diagnostic methods to be considered include radiologic evaluation, nonspecific blood tests, and establishing a microbiologic diagnosis. Also explored are the selection of the optimal antimicrobial regimen, monitoring the adequacy of therapy, and the use of hyperbaric oxygen therapy. The authors indicate that the approach to osteomyelitis depends upon the route by which bacteria gained access to bone, bacterial virulence, local and systemic host immune factors, and patient age. While imaging studies and
Studies

nonspecific blood tests may suggest the diagnosis, an invasive technique is generally required to identify the causative pathogens. Given the paucity of comparative clinical trials, antibacterial regimen selection has been largely guided by knowledge of the relative activities and pharmacokinetics of individual drugs which are supported by data from animal models. Definitive therapy often requires a combined medical and surgical approach. Currently, there are newer microvascular and distraction osteogenesis techniques, including use of laser doppler, that allow more complete surgical resection of infected material while maintaining function. Despite recent advances, many patients with osteomyelitis fail aggressive medical and surgical therapy. More accurate diagnostic methods, better was to assess and monitor the effectiveness of therapy, and novel approaches to eradicate sequestered bacteria are still needed. 4 tables, and 117 references.

[email protected]. Website: www.blackwell-science.com. Summary: This article reports on a study undertaken to identify the most accurate and efficient test for diagnosing Helicobacter pylori infection in primary care patients. A whole blood test, an ELISA, and carbon 13 urea breath test (CUBT) were evaluated in a primary care setting and validated against two different gold standards that used gastric (stomach) biopsies. The study included primary care patients who had complaints of dyspepsia lasting at least 2 weeks (n = 136) and who were referred for endoscopy. Data from these patients were compared with data from the gold standards. The positive predictive value of the whole blood test was in the range 71 to 75 percent, the ELISA 83 to 86 percent, and the CUBT 88 to 92 percent, while the negative predictive values were in the ranges 72 to 77 percent, 96 to 100 percent, and 95 to 98 percent, respectively. The sensitivity of the whole blood test was in the range 36 to 42 percent, the ELISA 93 to 100 percent, and the CUBT 92 to 97 percent, while the specificities were in the ranges 92 to 93 percent, 90 to 91 percent, and 93 to 95 percent, respectively. The positive predictive value of the ELISA dropped significantly at lower H. pylori infection rates. The authors conclude that both the ELISA and CUBT are effective in the primary care setting, while the whole blood tests produces inferior results. ELISA might, however, be less suitable for detecting H. pylori infection in a population with a low rate of infection. 1 figure. 3 tables. 24 references.

Stepwise Approach to the Diagnosis and Treatment of Hereditary Hearing Loss Source: Pediatric Clinics of North America. 46(1): 35-48. February 1999. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 32887-4800. (800) 654-2452. Summary: This article, from a monograph on hearing loss in children, suggests a stepwise approach to the diagnosis and treatment of hereditary hearing loss. The authors stress that the pediatrician can play a major role in the diagnosis, workup, and treatment of hereditary hearing impairment. Armed with the proper degree of suspicion, careful elicitation of family history, meticulous physical examination, evaluation of the audiogram, and adequate fund of knowledge of common types of genetic deafness, the pediatrician can make a timely diagnosis and appropriate referrals.

Blood Tests
This avoids delay in detection of significant hearing impairment and the associated lack of essential skills in speech, language, and social interaction. Early detection and intervention are best done with a multidisciplinary team approach. In the future, blood tests using genetic probes may be available to screen for many types of hereditary hearing impairment. The article also describes the work of the Hereditary Hearing Impairment Resource Registry (HHIRR), a registry that collects information about individuals with hearing impairment or deafness, matches families with appropriate research projects, and disseminates information to professionals and families about hereditary hearing impairment. An appendix lists helpful sources for additional information. 1 table. 25 references. •

[email protected]. Website: www.health.harvard.edu. Summary: This brief newsletter article, from the Harvard Heart Letter, reminds readers of the new safety recommendations for the use of cisapride (Propulsid). Cisapride is used to treat severe nighttime heartburn, usually caused by gastroesophageal reflux disease (GERD), a condition where the band of muscle that prevents stomach acid from leaking back into the esophagus relaxes spontaneously, creating a painful heartburn like sensation. Cisapride works by moving gastric acids through the digestive tract, thereby preventing their painful reflux into the esophagus. Because this drug has some risks, it is generally reserved for patients who have not responded well to lifestyle changes or other medications used to manage GERD. Serious adverse reactions occurring in patients on cisapride have included heart rhythm disorders and death (most often occurring in people with certain health problems or who were taking other medications). Although it could not find a direct link between the reported problems and cisapride, the U.S. Food and Drug Administration (FDA) did strengthen the precautions on using this drug. In January 2000, the FDA bolstered its efforts to reduce the likelihood of complications from cisapride by recommending that physicians consider performing an electrocardiogram and certain blood tests before prescribing it. The article lists the drugs that should not be combined with cisapride, as well as the complicating medical conditions that contraindicate its use.

Website: www.health.harvard.edu/newsletters/subinfo.html. Summary: This health education newsletter article describes nonalcoholic steatohepatitis (NASH), a common form of chronic liver disease in which the liver has excess fat cells and those cells cause inflammation. The author contends that NASH is another result of the epidemics of obesity and diabetes sweeping the United States. NASH is found most often in people who are 10 to 40 percent of their ideal body weight, or have diabetes, or both. At the cellular level, the changes produced by NASH resemble the liver tissue inflammation caused by alcohol. For up to 20 percent of people with NASH, the condition is the beginning of a dangerous cycle that leads to fibrosis (a buildup of fibrous tissue in the liver) and that can lead to life threatening cirrhosis (scarring of the liver). Most people with NASH have no symptoms, or vague symptoms, such as fatigue,

an achy feeling on the right side of the abdomen, and malaise (generally feeling bad). Liver function tests (blood tests) can show the first signs of trouble, but a liver biopsy must be used to confirm the diagnosis of NASH. Treatment involves weight loss, close monitoring of blood glucose levels in patients with diabetes, and cessation of alcohol consumption. Present research studies are investigating the role of vitamin E and ursodeoxycholic acid as possible drug therapies for NASH. •
15-Year Longitudinal Study of Blood Pressure and Dementia Source: Lancet. 347: 1141-1145. April 27, 1996. Summary: This journal article describes a 15-year study of the association between blood pressure and the development of dementia in older people. Residents of Goteborg, Sweden, who were 70 years in 1970-1972 participated in this study. A random subsample of 382 residents who did not have dementia on psychiatric evaluation at age 70 years were followed for 15 years with repeated neuropsychiatric examination and physical examination, electrocardiogram, chest radiograph, and blood tests. The results suggest that participants who developed dementia at age 79-85 years had significantly higher systolic blood pressure at age 70 years and significantly higher diastolic blood pressure at ages 70 and 75 years than did those who did not develop dementia. A significant association was found between higher diastolic blood pressure at age 70 years and subsequent development of Alzheimer's disease, and between higher diastolic blood pressure at age 75 years and subsequent development of vascular dementia. Participants with white matter lesions on computed tomography at age 85 years had higher blood pressure at age 70 than those without such lesions. In participants who developed dementia, blood pressure declined just before dementia onset and was then similar to or lower than that in participants without dementia. The authors conclude that increased blood pressure at age 70 years may increase the risk of developing dementia 10 to 15 years later. 4 figures, 1 table, 30 references.

Music Therapy Increases Serum Melatonin Levels in Patients With Alzheimer's Disease Source: Alternative Therapies. 5(6): 49-57. November 1999. Summary: This journal article describes a study of the effects of music therapy on neurotransmitters and neurohormones in patients with Alzheimer's disease (AD). Participants were 20 male patients at the Miami Veterans Administration Medical Center. The researchers took blood tests to determine the concentrations of melatonin, norepinephrine, epinephrine, serotonin, and prolactin in the patients before initiating the therapy, immediately at the end of four weeks of therapy, and at a six week followup after cessation of the therapy sessions. Melatonin concentration increased significantly after therapy and had increased further at the six week follow-up. Norepinephrine and epinephrine levels increased after four weeks of music therapy, but returned to pre-therapy levels at the follow-up. Prolactin and platelet serotonin levels were unchanged. The authors conclude that increased levels of melatonin following the therapy may have contributed to patients' relaxed and calm mood. 2 tables, 86 references.

Summary: This journal article discusses the treatment of excess disability in patients with early Alzheimer's disease (AD). Researchers conducted a prospective study of 117 patients referred to a Dutch memory clinic in the Netherlands. Ninety-nine patients had minimal or mild dementia, and 18 had moderate dementia. Excess disability, defined as treatable coexisting physical and psychiatric disorders, was assessed by neurologists with the Dutch version of the Cambridge Examination for Mental Disorders of the Elderly, a standardized medical history and physical examination, and measures of cognitive function, impairment in activities of daily living, behavioral changes, and caregiver burden. Seventy-seven forms of excess disability were already diagnosed and treated before referral in 61 of the 117 patients. Further clinical examinations and ancillary tests revealed 48 new diagnoses in 38 AD patients. Overall, 78 patients (66.6 percent of the sample) had a total of 125 conditions comprising excess disability. Of the ancillary tests performed, only the blood tests produced unexpected results with consequences for diagnosis, treatment, or outcome. The authors conclude that patients with AD should receive a careful examination with attention to secondary pathology and noncognitive symptoms; and they recommend doing blood tests in all AD patients. The question of which tests to routinely administer merits further study. 4 tables, 30 references. •
Dementia of the Alzheimer Type: Identification and Management of Neuropsychiatric Features Source: Older Patient. 4(3): 4-8. Fall 1990. Summary: This journal article examines the diagnosis, management, and clinical features of dementia of the Alzheimer type (DAT). In 1989, it was estimated that 4 million cases of DAT existed in the United States. The diagnosis of DAT involves documentation of intellectual decline, physical and laboratory examinations, blood tests, and neuroimaging. DAT has an insidious onset and is progressive, leading to eventual death in 6 to 12 years after onset. Patients with DAT experience memory loss, language and comprehension disturbances, spatial difficulties, mood disturbances, and psychoses. Management of psychoses is primarily pharmacologic, using neuroleptics (haloperidol, thiothixene, and thioridazine) with only a modest amount of benefit and numerous side effects. Nonpharmacologic interventions include gentle reassurance and distraction in an attempt to prevent a confrontation with the patient. The pharmacologic management of depression in DAT is similar to that employed in the nondemented depressed elderly. If a patient is physically violent, the caregiver should remove any potentially dangerous objects and assure his or her own safety. Restlessness, anxiety, and irritability are not always responsive to direct pharmacologic treatment. While the disorder is presently incurable, some of the pathologic behaviors commonly encountered can be manageable if appropriately identified and treated.

treatment are required because of the possibility of septic joint. The most common causes of acute monoarthritis are trauma, crystals, and infection. The most important cause of acute monoarthritis is infection, which must be excluded through the use of diagnostic joint aspiration and culture of synovial fluid. Other investigations include blood tests and radiographs of the involved joint. General principles of patient care management include joint rest, application of ice, and physiotherapy to help maintain joint range of motion and minimize muscle atrophy. Specific therapy includes antibiotics for bacterial monoarthritis, nonsteroidal anti-inflammatory drugs or intraarticular steroid injections for noninfectious inflammatory monoarthritis, and arthroscopy for internal derangement. Patients suspected of having septic arthritis should be started on empiric antibiotic therapy, pending synovial fluid Gram stain and culture results. 9 references, 1 figure, and 3 tables. (AA-M). •
Arthritis: Types and Diagnosis Source: Women's Health Digest. 2(2):122-125; 1996. Summary: This journal article for the general public and individuals with arthritis describes common rheumatic diseases. Connective tissue diseases include juvenile arthritis, lupus erythematosus, scleroderma, and Sjogren's syndrome. Examples of arthritis associated with spondylitis are ankylosing spondylitis and psoriatic arthritis. Types of infectious arthritis include Lyme disease and Reiter's syndrome. Metabolic diseases associated with rheumatic states are gout and pseudogout. Extra-articular disorders include bursitis and tendinitis. A common condition that may or may not be a specific disease is fibromyalgia. The major warning signs of arthritis are outlined. Techniques commonly used in the diagnosis of arthritis are discussed, focusing on the physical examination; laboratory tests, such as blood tests and joint aspiration; and radiologic studies, such as conventional x-rays, an arthrogram, radionuclide bone scans, computerized axial tomography, magnetic resonance imaging, and arthroscopy. 4 references and 2 figures.

[email protected]. Website: www.aafp.org. Summary: This journal article provides health professionals with information on the pathophysiology, clinical features, diagnosis, and management of osteoarthritis (OA). Cartilage destruction is the main feature of OA. Biomechanical and biochemical forces are involved in cartilage destruction. The typical patient who has OA is middle aged or elderly and complains of pain in the knee, hip, hand, or spine. Pain typically worsens with use of the affected joint and is alleviated with rest. The physical examination should include a careful assessment of the affected joints, surrounding soft tissue, and bursal areas. Although radiographs can usually confirm the diagnosis of OA, the findings are nonspecific. The cardinal radiographic features of OA are a loss of joint space and the presence of new bone formation or osteophytes. Most routine blood tests are normal in patients who have uncomplicated OA. Treatment of OA should be individualized. The safest initial approach is to use a simple oral analgesic such as acetaminophen. If pain relief is inadequate, oral nonsteroidal antiinflammatory drugs or intraarticular injections of hyaluronic acid like products should be considered. Intraarticular corticosteroid injections may provide short term pain relief in disease

flares. Alleviation of pain does not alter the underlying disease. Attention must also be given to nonpharmacologic measures such as patient education, weight loss, and exercise. Relief of pain and restoration of function can be achieved in some patients with early OA, particularly if an integrated approach is used. Patients with advanced disease may eventually require surgery, which generally provides excellent results. 2 figures, 5 tables, and 39 references. (AA-M). •
Arthritis 101: Sjogren's SyndroMen Source: Arthritis Today. 14(4): 32-33. July-August 2000. Summary: This journal article uses a question and answer format to provide people who have Sjogren's syndrome with information on the etiology, epidemiology, diagnosis, and treatment of this arthritis related disease affecting several organs. Sjogren's syndrome is an autoimmune disease in which lymphocytes attacks moisture producing glands, and, in some cases, the lungs, kidneys, liver, skin, nerves, or joints. Risk factors include being a postmenopausal woman, having an autoimmune disease, and having a family member with Sjogren's. Diagnosis is based on a complete physical examination; medical history evaluation; and various diagnostic tests, including the slit lamp test, the Schirmer test, a lip biopsy, and blood tests to detect antibodies. Although there is no cure for Sjogren's syndrome, it can be treated with medications and other measures to relieve the common symptoms of the condition. The article presents some general treatment modalities as well as treatments for some of the specific symptoms of Sjogren's. 1 figure.

Summary: This question-and-answer session explains what alkaline phosphatase (AP) is, and its use in diagnosing Paget 's disease ( PD ) and monitoring therapy. It reveals that this naturally produced enzyme in bone cells, once elevated, can point to a diagnosis of PD if blood tests show it is coming from the bone. Once diagnosed, successful treatment should show a drop in AP levels. In some cases, PD can be present (inactive or in small amounts) even when AP levels are normal.

Summary: This review article considers two topics pertinent to the need for pretreatment liver biopsy in patients with chronic hepatitis C: how liver biopsy results predict treatment outcomes; and how well biochemical blood tests and serological measures of fibrosis predict biopsy findings in chronic hepatitis C. The authors searched MEDLINE and other electronic databases from January 1985 to March 2002. Additional articles were sought in references of pertinent articles and recent journals and by querying experts. Articles were eligible for review if they reported original human data from a study that used virological, histological, pathologic, or clinical outcome measures. Studies suggested that advanced fibrosis or cirrhosis (scarring) on initial liver

biopsy is associated with a modestly decreased likelihood of a sustained virological response (SVR) to treatment. Also, studies relatively consistently showed that serum aminotransferases have modest value in predicting fibrosis on biopsy; that extracellular matrix tests hyaluronic acid and laminin may have value in predicting fibrosis; and that panels of tests may have the greatest value in predicting fibrosis or cirrhosis. Biochemical and serologic tests were best at predicting no or minimal fibrosis, or at predicting advanced fibrosis or cirrhosis, and were poor at predicting intermediate levels of fibrosis. Thus, evidence suggests that liver biopsy may have some usefulness in predicting efficacy of treatment in patients with chronic hepatitis C, and biochemical blood tests and serologic tests currently have only modest value in predicting fibrosis on liver biopsy. 2 tables. 81 references. •
AGA Technical Review on Constipation Source: Gastroenterology. 119(6): 1766-1778. December 2000. Contact: Available from W.B. Saunders Company. 6277 Sea Harbor Drive, Orlando, FL 19106-3399. (800) 654-2452 or (407) 345-4000. Summary: This technical review identifies a rational, effective, and cost effective approach to the patient presenting with constipation. The authors review the epidemiology of constipation, risk factors, the economic impact of constipation, the clinical features and pathophysiology, clinical evaluation, secondary encounters and referral consultations, diagnostic tests (balloon expulsion test, defecography, colonic transit, and anorectal manometry), medical management, and the role of surgery in treating constipation. Constipation is associated with inactivity, low caloric intake, the number of medications being taken, low income, and a low education level. Constipation is also associated with depression as well as with physical and sexual abuse. These are noted as risk factors, not necessarily as causative agents. The review summarizes three patient care algorithms. After the initial history and physical examination, patients can be classified into one of several subgroups. Standard blood tests and a colonic structural evaluation should be performed to rule out organic causes of the constipation. If the initial evaluation is normal or negative, an empiric trial of fiber (and or dietary changes) can be followed by simple osmotic laxatives. Most patients will obtain symptom relief with these measures. Patients who fail to respond to this initial approach are appropriate candidates for more specialized testing. 5 tables. 95 references.

Project Title: A NEW MARKER FOR COLON CANCER SCREENING Principal Investigator & Institution: Kinders, Robert J.; Bion Diagnostic Sciences 12277 134Th Crt Ne Redmond, Wa 98052 Timing: Fiscal Year 2001; Project Start 20-SEP-2001; Project End 31-AUG-2002 Summary: (provided by applicant): Replace the current FOBT (fecal occult-blood tests) used in CRC screening for colorectal cancer in individuals over age 50. We have shown upregulation of TAA mRNA expression in colon tumors. We have produced monoclonal antibodies and affinity purified antisera to the TAA and have used these to formulate a prototype sandwich enzyme immunoassay in a microplate format. We have used this assay to test 70 stool specimens and a number of colonic washes from patients in which a tumor was subsequently found. In a head-to-head comparison with two different fecal occult blood tests (FOBT), the prototype sandwich assay has demonstrated superior clinical diagnostic performance to both. Work has begun on assembling two, 500 specimen panels to demonstrate utility of the marker in relevant populations. Additional Phase I objectives are to 1) generate additional monoclonal antibodies to the TAA; 2) complete cloning and sequencing of the TAA from human tumor specimens. The product we visualize is a low cost, one-step immunoassay device suitable for use in a screening mode in which patients with a positive test result would be worked up by sigmoidoscopy or colonoscopy. PROPOSED COMMERCIAL APPLICATIONS: Replace the current FOBT ( fecal occult-blood tests) used in CRC screening with an immunoassay for a TAA found in stool. A successful product will more than double the number of cancers detected, detect pre-cancerous lesions not currently detected, and cut the number of false-positives by 3 to 5 fold or more.

Project Title: AV SHUNT IMPLANTATION IN HEMODIALYSIS PATIENTS Principal Investigator & Institution: Harker, Laurence A.; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2001 Summary: This is a placebo-controlled, safety and efficacy dose-finding study assessing the effects of dosing FFR-rFVIIa vs placebo in 4 cohorts of patients each (4:1 randomization favoring active therapy) on AVG 111In-platelet deposition at the time of AVG surgical placement or replacement (primary outcome). Imaging of 111In-platelets accumulating at the sites of AVG anastomoses, and an escalating bolus FFR-rFVIIa in subsequent cohorts will establish safety, tolerance and an effective antithrombotic dose regimen for FFR-rFVIIa administration in dialysis patients undergoing surgical AVG placement or replacement. This dose will subsequently be used in a controlled clinical trial of AVG failure. We also propose to compare the dose-response effects of FFRrFVIIa vs placebo on post-operative changes in blood tests of thrombosis, tests of hemostasis and measured surgical blood loss.

Project Title: COLORECTAL CANCER SCREENING--FECAL BLOOD VS DNA Principal Investigator & Institution: Ahlquist, David A.; Mayo Clinic Rochester 200 1St St Sw Rochester, Mn 55905 Timing: Fiscal Year 2001; Project Start 15-JUN-2001; Project End 31-MAY-2004 Summary: APPLICANT?S Colorectal cancer remains the second leading cause of malignant death, and better preventive strategies are needed. Stool testing, unlike other conventional screening approaches, is noninvasive and requires no cathartic preparation. However, widely-used fecal blood tests yield frequent false-negative and false-positive results that lower the screening effectiveness and raise program costs. There is a compelling biological rationale to target altered DNA exfoliated from neoplasms into stool, and multiple DNA markers would need to be targeted due to the genetic heterogeneity of colorectal neoplasia. Preliminary data suggest that a prototype multi-target DNA-based assay system has potential to detect screen-relevant colorectal neoplasia (early-stage cancer and advanced adenomas) with substantially higher sensitivity and specificity than that of fecal blood tests. The overall objective of this application is to prospectively assess the fecal DNA-based test as a promising new approach to the general screen-detection of colorectal neoplasia. A 3-year cross-sectional multicenter study is planned to compare the validity of the DNA-based test and the most commonly used fecal blood test (Hemoccult) for identification of screen-relevant colorectal neoplasia in 2900 demographically representative average-risk persons using colonoscopy as a gold standard. The performance of the DNA-based test will also be compared to a surrogate for flexible sigmoidoscopy (distal 60 cm of colonoscopy) and to the combination of sigmoidoscopy + Hemoccult. The design will further allow an assessment of the impact of dietary, medication, demographic, and other covariates on test outcomes. Assays will be performed blindly at central laboratories. A specimen bank will be maintained as an important resource for the economical evaluation of additional markers. A state-of-the-art web-based data management system will be employed to efficiently enter and transfer data across the six participating centers with the highest quality control. If the DNA-based test proves to have greater screening accuracy than fecal blood testing, this could translate into more effective cancer control and more efficient use of our limited health care resources.

Project Title: GENETIC VARIABILITY IN COLORECTAL NEOPLASIA Principal Investigator & Institution: Gerner, Eugene W.; Professor; University of Arizona P O Box 3308 Tucson, Az 857223308 Timing: Fiscal Year 2002; Project Start 05-SEP-2002; Project End 31-MAR-2007 Summary: (provided by applicant): The translational goal of this project is to develop simple blood tests to predict colon cancer risk and to tailor therapy for colorectal intraepithelial neoplasia (IEN). Diagnosis of colon cancer at an early stage continues to be problematic, and response to treatment is limited in late stage colon cancer. Better measures of risk will contribute to colon IEN prevention or earlier detection. Earlier detection combined with methodologies to predict response to therapy will decrease colon cancer incidence and mortality. The hypothesis to be tested in this proposal is that the risk of colorectal cancer is influenced by genetic variability affecting the expression/function of the adenomatous polyposis coli (APC) tumor suppressor gene and/or APC modifier genes, such as ornithine decarboxylase (ODC). Measures of this genetic variability may be prognostic and/or predictive factors for colorectal IEN. To test this hypothesis, four specific aims are proposed. First, we will measure specific
18
Blood Tests
mutations in the APC tumor suppressor gene in colorectal adenomas from participants in colon cancer prevention trials. Second, we will measure germline polymorphism frequencies in codon 1822 of APC. We will determine associations between genetic variability in APC with dietary factors and adenoma recurrence in this patient group. Third, we will measure the genetic variability in the c-myc-dependent region of the ODC promoter in groups at risk for colorectal IEN, and determine whether polymorphisms are associated with adenoma recurrence. Finally, we will ascertain the functional significance of these polymorphisms in intestinal carcinogenesis. Future studies will measure variability in other downstream mediators of APC. These other mediators include networks regulating polyamine and arachidonic acid metabolism. Since these pathways are targets for IEN therapy (e.g., DFMO, NSAIDs), genetic variability in these pathways may be predictive factors for therapeutic response to treatment.

Project Title: HOE901 VERSUS NPH HUMAN INSULIN WITH TYPE I DIABETES MELLITUS Principal Investigator & Institution: Feinglos, Mark N.; Duke University Durham, Nc 27706 Timing: Fiscal Year 2001 Summary: PURPOSE: The purpose of this study is to compare the effects of HOE 901 and NPH on glycated hemoglobin and to compare the safety of HOE 901 with NPH in subjects with type I diabetes mellitus. A comparison between the two treatments will also be made in terms of blood glucose variability, hypoglycemia, other indicators of metabolic control, quality-of-life, and pharmacoeconomics. METHODS: This is a phase III, randomized, multicenter, open, NPH human insulin controlled, randomized (1:1), 28-week parallel-group study with two treatment groups (HOE901 and NPH human insulin). A total of 520 patients ( a total for all sites) will be evaluated in this study. The study consists of a 1 to 4-week screening phase and a 28-week treatment phase which includes an initial active dose titration phase. Subjects randomized to the NPH insulin group will continue their previous regimen of injections per day. Subjects randomized to HOE901 will receive a single injection of HOE 901 at bedtime. Both treatment groups will also receive regular insulin in addition to either HOE901 or NPH human insulin. The subjects will be stratified by whether they were being treated with a basal insulin once versus twice daily. This study will involve 5 outpatient visits and 3 inpatient visits. During the screen visit, subjects will undergo a history and physical examination, blood tests, pregnancy screen, dilated eye exam, and fundus photography. Subjects will be instructed in home blood glucose monitoring, issued a glucose meter and supplies, and will be asked to monitor their blood glucose 4x/day. At the following visit, patients who qualify will be admitted to the GCRC for approximately 36 hours, during which 24 hr blood glucose samples will be taken. Patients will also have an EKG and blood tests. Patients are randomized at this visit. Outpatient follow-up visits including blood tests will occur at Weeks 1 & 4. Patients will be readmitted for an inpatient stay, including 24 hr sampling, at Week 8. Outpatient follow-up visits including blood tests will occur at Weeks 12 & 20, with optional eye exam and fundus photos at Week 12. The final admission will occur at Week 28. In addition to 24 hr sampling, an EKG, eye exam, fundus photos, and blood tests will be performed. Patients will restart their prestudy insulin regimen at this visit. RESULTS AND CONCLUSIONS: The study was completed in June 1998. This is a pharmaceutical-sponsored, multicenter study, and results have not been provided to date. SIGNIFICANCE: Type I diabetes mellitus is characterized by

general insulin deficiency due islet beta-cell loss and requires insulin replacement therapy. Normal pancreatic beta-cells secrete approximately 50% of insulin as boluses in response to food and the rest as a continuous basal secretion. Longer-acting insulins such as NPH or Ultralente are often used to simulate endogenous basal insulin in the treatment of type I diabetes. However, neither NPH nor Ultralente provides a stable 24 hr basal insulin supply because either the duration of action is too short (NPH) or absorption from the site is erratic (Ultralente). NPH also often results in nocturnal hypoglycemia due to plasma insulin peaks during the night. Consequently, the bedtime NPH dose cannot be safely increased as appropriate, resulting in elevated blood glucose in the morning, a major obstacle to overall euglycemia. The Diabetes Control and Complications Trial has shown that tight blood glucose control greatly reduces the risk of diabetic complications such as retinopathy, neuropathy, and nephropathy. Human insulin analogue HOE901 is a long-acting insulin that, if proven safe and effective, can be given as a single daily injection to provide near normal blood glucose control and a smoother 24 hr basal insulin profile than previously possible with available medications. FUTURE PLANS:The results of this study will provide the basis for future investigation of HOE901. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: SCREENING
INTERVENTIONS
TO
INCREASE
COLORECTAL
CANCER
Principal Investigator & Institution: Menon, Usha; None; University of Utah 200 S University St Salt Lake City, Ut 84112 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 30-JUN-2003 Summary: Colorectal cancer (CRC) is the third leading cause of cancer death in the United States with the majority of CRC diagnosed in those aged 50 or older. Prospective data indicate that annual fecal occult blood tests (FOBT) can decease mortality from CRC. The American Cancer Society recommends an annual FOBT and a flexible sigmoidoscopy every 5 years. Utilization of these tests is very low, ranging from 19% to 39%, especially among those who are 50 or older and most at risk for developing the disease. Tailored interventions have demonstrated significant increases in mammography use, and may be effective in the area of CRC screening as well. The purpose of this study is to compare the effectiveness of a tailored versus a non-tailored intervention designed to increase the use of FOBT and sigmoidoscopy, and to determine its effect on cognitive stage of behavior. The theoretical framework for this study was derived from the Health Belief and Transtheoretical Models. Institutional review board approval will be obtained before data collection. All instruments proposed in this study were previously tested for reliability and validity. Trained research assistants will contact members of a Midwest-based health maintenance organization (HMO), aged 56 or older and who have not had an FOBT in the last 15 months. Once eligibility criteria is verified, those who agree to participate with be randomized to one of three groups; 1) control, 2) tailored print communication, and 3) non- tailored print communication. Baseline data will be collected by telephone from a sample of 600 HMO members. Interventions will be mailed 2 weeks from the baseline interview, and post intervention interviews conducted 2 months from the intervention. Logistic regression will be conducted modeling the odds of having an FORT or sigmoidoscopy by intervention group. Those independent variables significant in bivariate analyses at p equal to or <.20 will be entered in to a separate logistic regression model to identify predictors of FOBT and sigmoidoscopy use. Results will be useful in testing tailored interventions to increase FOBT and sigmoidoscopy in managed care settings.

Project Title: LAB-IN-A TUBE BLOOD TEST SYSTEM Principal Investigator & Institution: Chen, Shuqi; Iquum, Inc. 214 Lincoln St, Ste 300 Allston, Ma 02134 Timing: Fiscal Year 2002; Project Start 30-SEP-2000; Project End 31-JUL-2004 Summary: (provided by applicant): The objective of this project proposal is the development of a commercially viable diagnostic blood testing product that will meet the growing demand for practical near-patient testing. The product will be built on the lab-in-a-tube platform, which uses novel sample handling, microfluidic, and imaging technology to achieve system miniaturization, low cost, high flexibility, and improved safety. The successful commercialization of this product will improve public health by enabling caregivers to easily collect more information about a patient's condition. They will accomplish this by directly conducting blood tests on-site, during the patient's visit.lQuum proposes to continue the development of the lab-in-a-tube platform by designing and building prototypes of the three major components of the system: the desktop analyzer; the integrated sample collection and processing container, and the multiple-use, disposable reagent cartridge. The company will concurrently develop platelet function and coagulation assays as the first applications for the lab-in-a-tube system. The flexible detection and processing technology of the product enable the platform to conduct numerous types of tests, including blood typing, cell counting, and immunoassay. These assays will be developed separately and will showcase the full multifunction capability of the lab-in-a-tube system. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: MOLECULAR DIAGNOSIS OF SARCOMAS Principal Investigator & Institution: Baker, Laurence H.; Internal Medicine; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2003 Summary: (provided by applicant): We will elaborate serum quantitative-PCR (QPCR) and peripheral blood RT-QPCR tests to diagnose the presence of sarcomas. We aim to construct simple blood tests to screen people at increased risk for sarcoma, to evaluate the initial tumor, to assess therapy of patients with sarcoma and/or to follow people who have been treated for sarcoma. Sarcomas were chosen initially because we found appreciable amounts of lysed tumor cell DNA in the serum. This enabled us to propose a generic test based on quantitative differences of tumor suppressors and oncogenes in sarcoma. Subsequently, more specific tests have become available involving aberration of the c-kit gene in GI stromal tumors and specific translocations that characterize defined sarcoma types. We add these more specific tests to our previous application that was based on the generic tests only. 1. Test the primary sarcoma to assay the QPCR markers that show quantitative changes and the RT-QPCR markers that show specific translocations. 2. Monitor the serum simultaneously to determine the QPCR anomalies therein and/or the peripheral blood to screen for specific RT-QPCR markers of translocation. The usefulness of these determinations is supported by our preliminary results demonstrating the presence of QPCR serum anomalies in untreated sarcoma patients. 3. Monitor the serum and peripheral blood longitudinally to screen for these molecular anomalies and (if necessary) new anomalies to detect metastases and/or recurrence that might not be apparent clinically. If we detect useful serum QPCR anomalies and/or peripheral blood anomalies in particular situations in phase I, we will

expand the studies in phase II to perform longitudinal QPCR assays useful in a given situation. We will use the test to perform diagnosis of at-risk and treated populations, to monitor cancer cell lysis before and during treatment, to monitor the efficacy of cancer treatments and to detect recurrences. This is proposed as an R21 (one year)/R33 (three year) grant to determine the feasibility of these studies for sarcomas in the R21 phase. If more studies are indicated, the R33 phase would support the longer-term longitudinal studies required to demonstrate how best to use this test to follow the course of sarcomas.

Project Title: MOLECULAR GENETICS OF COLOR VISION Principal Investigator & Institution: Deeb, Samir; Research Professor; Medicine; University of Washington Seattle, Wa 98195 Timing: Fiscal Year 2001; Project Start 01-DEC-1989; Project End 30-NOV-2003 Summary: The central objective of this proposal is to define the molecular genetics of red/green color vision by relating the molecular genetics of the X- linked photopigment genes to their expression in the retina and to the color vision phenotype. The red and green pigment genes are arranged in an array on the X-chromosome consisting of a single red and one or more green pigment genes. Deletion of genes or formation of hybrid genes (red-green and green-red) due to illegitimate recombination at this locus causes color vision defects. However, not all other gens of the red/green array are expressed in the retina, creating uncertainties in predicting color vision phenotype from genotype. Understanding the mechanism by which selective expression of these genes is accomplished is fundamental to defining genotype-phenotype relationships. We have delineated critical regulatory regions of the red-green gene locus and detected proteins that bind to them. A major aim of this proposal is to clone and character the transcription factors that play major roles in regulating expression of the visual pigment genes. We will map the genes encoding these factors on human and mouse chromosomes. Map positions will be correlated with known loci associated with retinal diseases. We developed a rapid method for determining gene order in males who have up to three pigment genes in their arrays and found evidence for a role of gene order in gene expression and color vision. We propose to advance their method in order to determine gene order in the majority of individuals. Knowing the sequence and gene order will allow more precise prediction of the spectral sensitivities of clones and the color vision phenotype. The ratio of red to green cones was determined indirectly by measuring relative levels of mRNA in postmortem human retinae. We propose to determine the ratio and distribution of cones in the retina directly by in situ molecular techniques. The findings will be of fundamental importance for the visual sciences. We observed a very high frequency of green-red hybrid genes among Africans. We will investigate the sequence of these hybrids and determine their position in the array. Elucidation of the molecular mechanism of expression of this locus affecting sensory perception is a model for expression of genes in other complex loci. These studies may lead to rapid and accurate blood tests for color vision defects. The novel photoreceptorspecific genes we propose to clone may be good candidates for some of the inherited retinal diseases. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: N3 FATTY ACIDS EFFECT ON SICKLE CELL PAIN EPISODES Principal Investigator & Institution: Eckman, James R.; Professor; Medicine; Emory University 1784 North Decatur Road Atlanta, Ga 30322
22
Blood Tests
Timing: Fiscal Year 2001; Project Start 01-JUL-1999; Project End 31-MAY-2003 Summary: Our studies show that sickle cell disease (SCD) patients have platelet activation, increased thrombin formation and fibrinolysis, in vivo, and that activation of thrombosis increases significantly during pain episodes. Moreover, in a small controlled pilot trial evaluating dietary n-3 fatty acids (n-3 Fas) in SCD patients with frequent pain episodes, the frequency of pain episodes was significantly decreased in dietary n-3 FAtreated patients compared to olive oil treated controls. Moreover, markers of thrombosis decreased to near those observed in the control subjects. In addition, the Multicenter Study of Hydroxyurea in Sickle Cell Anemia reports that reduction in pain frequency with hydroxyurea was directly correlated to reduction in neutrophil and monocyte counts. We hypothesize that pain episodes in SCD patients are caused by local microcirculatory occlusion mediated by sickle cells that cause microvascular damage inducing expression of adhesion molecules and counter-receptors by monocytes and endothelial cells. This stimulates TF expression by vascular cells and blood monocytes causing TF induced thrombin production and thrombosis. TF expression provides feedback amplification via thrombin-mediated monocyte activation, accumulation, expression of TF that increases thrombosis enhancing microvascular occlusion and ischemic damage. Because preliminary findings indicate that dietary n-3 FAs are safe and down-regulate multiple membrane-activation pathways of circulating blood and vascular wall cells, we propose to test the therapeutic efficacy of dietary n-3 FAs by conducting a double-blind, olive oil- controlled clinical trial of dietary n-3 FAs in 60 SCD patients with frequent pain episodes, randomly allocated to dietary n-3 FAs or control olive oil. The primary outcome is the frequency of pain episodes. Based on the pilot study, this trial has a 90 percent probability of demonstrating a 50 percent decrease in frequency of pain episodes. Our hypothesis will be tested in secondary analysis of the effects of dietary n-3 FAs on blood markers of thrombosis and inflammation. Blood tests of thrombosis will include flow cytometric assessment of platelet activation and microparticle formation, thrombin:antithrombin complex (TAT) levels, activation fragment of prothrombin (F1.2), thrombin's fibrinogen cleavage product (FPA), plateletspecific secretion proteins platelet factor 4 (PF4) and beta-thromboglobulin (betaTG), and products of fibrinolysis including plasmin-antiplasmin complex (PAP) and Ddimer. Blood tests of inflammation to be measured include flow cytometric assessment of monocyte activation and expression of tissue factor and plasma levels of soluble vascular cell adhesion molecules (sVCAM) and monocyte chemotactic protein-1 (MCP1).

Project Title: NIDDM SUSCEPTIBILITY GENES IN A BIRACIAL COHORT Principal Investigator & Institution: Brancati, Frederick L.; Associate Professor; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, Md 21218 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-JUL-2004 Summary: (Adapted from the Investigator's Abstract) Type 2 diabetes mellitus and its atherosclerotic complications impose a substantial burden on health of Americans in general and on African Americans in particular. Recent discoveries in molecular genetics have lead to the identification of functional variations in several candidate genes for susceptibility to obesity, insulin resistance, and/or diabetes. These include genes which code for beta-2and beta-3 adrenergic receptors, insulin receptor substrate 1, fatty acid binding protein 2, frataxin, and leptin receptor. If their role as novel susceptibility factors is confirmed, these variants promise to illuminate the pathophysiologic basis of diabetes and diabetes related cardiovascular diseases, accelerate the development of chemopreventive agents, and facilitate the conduct of prevention trials by marking individuals at high risk. Unfortunately many previous association studies of these mutations in human populations have been limited by small, selected study samples; by limited cross-sectional data on behavioral factors and on cardiovascular risk phenotype; and by paucity of data on African Americans. The investigators, therefore, propose to conduct an epidemiologic study of functional variants in 10 candidate genes for susceptibility to type 2 diabetes, obesity, and insulin resistance. The main objective will be to detect modest effects consistent with polygenic nature of diabetes but with better sensitivity and precision than previous association and linkage studies. The study sample will a community based cohort of 3,250 African Americans and 3,250 Whites aged 45 to 64 who are participants in the ongoing Atherosclerosis Risk in Communities (ARIC) study. Supported by NHLBI the ARIC study has assembled an extensive data base including behavioral assessment (e.g. diet and physical activity), anthropometry, laboratory blood tests (e.g. oral glucose tolerance test and serum lipids), and carotid ultrasonography as well as clinical events and mortality. Using race specific case-control, cross-sectional, and longitudinal analyses the investigators will determine if these putative diabetes alleles are associated with incident and prevalent diabetes, with obesity and weight gain, with hyperinsulinemia in non-diabetic individuals with the presence of an adverse cardiovascular risk factor profile, and with atherosclerosis progression and cardiovascular disease incidence over 12 years of follow up. The investigators will assess how behavioral and environmental factors such as obesity, diet, and physical activity, influence the expression of genetically conferred risk. Strength of this proposal include the close collaboration between clinical, epidemiologic, and laboratory researchers, a wealth of prospectively collected data from an NIH sponsored study, and a sample size large enough to detect modest gene effects and to investigate gene-gene and gene-environmental interactions. Most important, this study will provide unique information on the expression of diabetes susceptibility genes in the general population and possibly suggest genetic explanations for the excess prevalence of type 2 diabetes and obesity in African Americans.

Project Title: RAPID ON-SITE CYANIDE ASSAY FOR BLOOD AND SALIVA SAMPLES Principal Investigator & Institution: Goodridge, Carolyn F.; Cc Technology, Inc. Box 3136, 813 S 2Nd St Laramie, Wy 82071 Timing: Fiscal Year 2003; Project Start 01-APR-2003; Project End 31-MAR-2004

Blood Tests
Summary: (provided by applicant): The specific aim of this project is to develop a rapid test for the detection of cyanide in blood and saliva. Poisoning due to cyanide can occur vary rapidly in less than a few minutes, but current tests require at least 2 -3 hours for results to be reported. In rural communities, blood tests for cyanide are sent out for analysis and often several days pass before levels are reported. The current method is a head-space GC technique that uses a strong acid to liberate hydrogen cyanide from cyanomethemoglobin. This results in the administration of antidotal therapy without conformation of poisoning. The antidote, intravenous sodium nitrite, can in itself cause severe poisoning due to hypotension and complications can be exacerbated by anemia. Our technology centers on the strong affinity of cyanide for gold nanoparticles. We have demonstrated that gold nanoparticles can bind free cyanide in aqueous solutions at levels of less than 10 ppb. Most of our prior work has been with aqueous cyanide and gold nanoparticle suspensions, however, some work with HCN detection has been performed with gold nanoparticle impregnated test strips. For this project, we will examine a test for cyanide in blood or saliva using a test strip and a releasing agent to create free cyanide from a biological sample. An example of a potential releasing agent is a strong such as sulfuric acid. Gas permeable membrane technology will also be tested to prevent mixing of releasing agents with the gold nanoparticles. In addition to the chemistry of gold nanoparticles and release of cyanide from cyanomethemoglobin we will show the feasibility of a low cost spectroscopic measurement system. We will eliminate the large and costly portion of Raman spectrometers that is associated with dispersion of the spectrum and replace it with a very small inexpensive filter system. This new system will be designed for handheld use by first response personnel for onsite analysis. The long-term objective of this project will be to provide emergency personnel with small handheld device to measure concentrations of cyanide in blood or saliva. We are working with a local fire department to ensure that the design and specifications match the needs of first response personnel.

Project Title: ROLE OF ADIPOSE TISSUE IN VITAMIN D METABOLISM Principal Investigator & Institution: Blum, Miriam; None; Tufts University Boston Boston, Ma 02111 Timing: Fiscal Year 2001; Project Start 01-SEP-2001; Project End 31-AUG-2006 Summary: (provided by applicant): Vitamin D has important effects upon calcium and bone metabolism and may be involved in the functioning of many other systems. Vitamin D insufficiency contributes to bone loss in the elderly and has recently been found to be quite prevalent in the northeast US. In both rodents and humans, adipose tissue is a major repository for vitamin D, however the function of adipose tissue in vitamin D metabolism is uncertain and factors affecting the assimilation and release of vitamin D from adipose tissue need to be elucidated. The overall purpose of this research project is to begin to define the role of adipose tissue in vitamin D metabolism. In this regard, we hypothesize that: 1. Vitamin D intake influences the level of vitamin D in adipose tissue 2. The vitamin D content of adipose tissue varies with season 3. Higher fat stores of vitamin D at the end of the summer will reduce the wintertime decline in blood 25-hydroxy vitamin D levels. To test these hypotheses, detailed investigations of vitamin D content in adipose tissue, body composition measurements, blood tests and dietary intake will be conducted in adult men and women participating in a longitudinal study. The proposed study consists of a seasonal observational period followed by a randomized placebo control trial of varying doses of oral vitamin D. In preparation for this study, I will train in vitamin D assay techniques and help refine the

method for extracting and measuring vitamin D content in adipose tissue. Studying the role of adipose tissue in vitamin D metabolism will help increase our understanding of vitamin D physiology. It may also enable us to better understand the mechanisms involved in vitamin D insufficiency and give us greater insight into the management of this prevalent condition. In addition, the proposed study sets the groundwork for future studies that are essential to my development as an independent investigator. The proposed study as well as the other components of the K23 Award will enable me to broaden my skills in clinical research and increase my depth of knowledge and technical skills. The supportive environment and distinguished collaborators that are part of this proposal will provide me with the guidance that I need to pursue my research plans as I make the transition to independent clinical investigator.

Project Title: SMOKING CESSATION IN THE CHEST PAIN OBSERVATION UNIT Principal Investigator & Institution: Bock, Beth C.; Assistant Professor; Miriam Hospital Providence, Ri 02906 Timing: Fiscal Year 2001; Project Start 01-AUG-1999; Project End 31-JUL-2003 Summary: Approximately 4.5 million Americans visit the emergency department each year with symptoms of chest pain. Over 90% are eventually ruled out for myocardial infarction and other acute cardiovascular events. Three serial blood tests taken at 8 hour intervals are needed to rule out MI, requiring a 24-hour stay in the emergency department Observation Unit (OU). During most of this time patients are at bed rest. While approximately 25% of these patients are smokers, nothing is currently being done to address smoking cessation with these patients. The experience of hospitalization for chest pain is intense, but transient. The long term impact of this experience on smoking cessation and motivation to quit is unknown. The effects of this experience on the individual's perception of risk from smoking, and how personal coping style may interact with the OU experience are also unknown. We will recruit 722 smokers and randomly assign them to either (a) Usual Treatment, or (b) Enhanced Treatment for smoking cessation. Enhanced Treatment consists of a brief intervention by the attending physician, a 30 minute motivationally tailored cognitive behavioral interview with a trained health educator, nicotine replacement when appropriate, and scheduled followup phone contacts. Data will be collected on smoking attitudes, motivation and behaviors, nicotine dependence, risk perception, psychological coping style. Follow- up assessments will be conducted at l, 3, and 6 months after recruitment. An implementation index of the amount and duration of all smoking interventions delivered in both conditions will be created statistically, and analyzed for effects on smoking outcomes and interactions with coping style and risk perception, and determination of optimal cost-benefit ratios. Primary outcome analyses will examine 7day point prevalence abstinence at each follow-up and survival analysis (time to 1st relapse). We hypothesize that; (1)smokers given the Enhanced Treatment will show significantly higher abstinence rates at 6 months post-tx, and (2) greater improvement variables mediating readiness to quit (ie., decision making, self-efficacy), compared to Usual Care and, (3) coping style and risk perception will moderate the efficacy of the intervention for all subjects. Information provided by this study is needed to develop specific smoking interventions targeted to this population. Broad application of these findings should reach over l million smokers per year.

Project Title: VIRAL AND HOST FACTORS IN THE TRANSMISSION & PATHOGENESIS OF HIV Principal Investigator & Institution: Kost, Rhonda; Rockefeller University New York, Ny 100216399 Timing: Fiscal Year 2001 Summary: Subjects are recruited through local physician networks and are interviewed over the telephone to be sure they meet the appropriate disease definition (multiplyexposed, acute seroconvertor, or long-term survivor). If the history matches the disease definition to be studied, they are scheduled for a visit at which time more extensive history is obtained, informed consent is signed, and screening blood tests are drawn. The blood tests vary based upon the disease state that is being studied. For instance, in acute seroconvertors, we look for evidence of falling viral load and an increasing immune response; in long-term survivors we look for low viral load and normal CD4 cell counts in someone with documented infection for >10 years; in exposed-uninfected subjects we look for evidence of sero-negativity in someone with a documented history of multiple high risk exposures. Once a subject meets the specific disease definition, he or she is asked to return for further phlebotomy. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: WARFARIN VS ASPIRIN FOR INTRACRANIAL ARTERIAL STENOSIS Principal Investigator & Institution: Chimowitz, Marc I.; Neurology; Emory University 1784 North Decatur Road Atlanta, Ga 30322 Timing: Fiscal Year 2001; Project Start 25-SEP-1998; Project End 31-JUL-2003 Summary: Background and Relevance. Atherosclerotic stenosis of the major intracranial arteries causes 40,000 strokes per year in the USA, costing the country at least 600,000,000 dollars annually. There have been no prospective trials evaluating optimal medical therapy for this disease. The main objective of this clinical trial is to compare warfarin (INR 2-3) with aspirin (1300 mg/day) for preventing stroke (ischemic and hemorrhagic) and vascular death in patients with symptomatic stenosis of a major intracranial artery. Study Design. Prospective, randomized, double-blind, multi-center trial. The sample size required will be 403 patients per group (based on stroke and vascular death rates of 33 percent/3 years in the aspirin group vs 22 percent/3 years in the warfarin group, an alpha of 0.05, beta of 0.80, a 24 percent withdrawal of therapy rate, and a 1 percent drop out rate). Conduct of Trial. Patients with transient ischemic attack (TIA) or stroke caused by angiographically proven stenosis (greater than or equal to 50 percent) of a major intracranial artery will be randomized to warfarin or aspirin.
Studies
27
The dose of warfarin will be adjusted to maintain the INR between 2-3 based on monthly blood tests. Patients will be contacted monthly by phone and examined every four months (mean follow-up of 3 years) to determine whether any endpoints have occurred. The primary analysis will compare the rates of stroke (ischemic and hemorrhagic) and vascular death in the two treatment groups. Secondary analyses will compare the two treatment groups with respect to rates of i) all vascular deaths and disabling stroke, ii) all stroke (ischemic and hemorrhagic), iii) fatal and nonfatal ischemic stroke, iv) all ischemic stroke, myocardial infarction and vascular death, v) all major systemic and any intracranial hemorrhage, vi) all ischemic stroke in the territory of the stenotic intracranial artery. Conclusion. This study will 1) define optimal medical therapy for patients with symptomatic intracranial arterial stenosis, and 2) identify patients whose rate of ischemic stroke in the territory of the stenotic intracranial artery on best medical therapy is sufficiently high (i.e., greater than or equal to 6 percent per year) to justify a subsequent trial comparing intracranial angioplasty with best medical therapy in these patients.

Project Title: YOUNG ADULT VERY LOW BIRTHWEIGHT--NEONATAL BLOOD TRANSFU Principal Investigator & Institution: Hack, Maureen; Professor of Pediatrics; Case Western Reserve University 10900 Euclid Ave Cleveland, Oh 44106 Timing: Fiscal Year 2001 Summary: Prior to 1986 risk factors for hepatitis C, or non A, non B hepatitis as it was then called, included transfusions of blood and blood products, needle sharing and intravenous drug abuse, health care employment with frequent exposure to blood, sexual contact with, or household exposure to a person who had hepatitis C, and possibly sexual contact. The overall prevalence of hepatitis C infection ranges from 0.5% for low risk blood donors to 60%-90% for drug users and hemophiliacs who have received multiple blood transfusions. Five to 15% of persons transfused prior to 1986 contracted hepatitis C. In examining these results, it is important to take into account that the majority of reports between 1990 and 1992 pertain to results obtained using first generation type radioimmunoassay tests, which, as noted above, have a poor sensitivity and predictive value. There is very little known of the natural history of HCV infections in childhood. High risk groups include children requiring multiple blood transfusions and/or pooled blood products, as well as those born to Hepatitis C positive mothers. It is postulated that the natural history and risk of progression to liver disease in children will vary depending on the underlying condition for which the blood products were received, but that it is likely that 40% of infected children will develop chronic hepatitis with progression at some time to cirrhosis, and that they will be at increased risk of developing hepatocellular carcinoma. This progression may extend over 30 to 40 years. The Specific Aims are: 1) to examine the prevalence of Hepatitis C infection in a cohort of very low birthweight young adults. 2) to estimate the risk of hepatitis C infection according to the total volume of blood received, and the number of different donors. 3) among Hepatitis C positive VLBW subjects, to identify the neonatal risk factors and childhood and adolescent health and behavioral risk factors associated with both the development of Hepatitis C liver disease and its severity. 4) to refer the Hepatitis C positive VLBW subjects for the best possible treatment currently available, to prevent the development of disease and/or deterioration of the liver associated with viral infection. 5) to inform the Hepatitis C positive VLBW subjects of the results of their tests, and to counsel them concerning health risk behaviors (such as drinking alcohol) and
28
Blood Tests
hepatotoxic medications, and precautions they might need to take to prevent transmission to close intimate partners. Hypotheses: 1) That 10-15% of the very low birthweight subjects who received neonatal blood transfusions will be Hepatitis C positive at 20 years of age. 2) That the probability of testing Hepatitis C positive will depend on the number of transfusions from different donors and the total volume of blood received during the neonatal and behavioral risk factors. We propose, initially, a pilot study to examine the prevalence of Hepatitis C infection among the 20 year-old subjects in our main study born in 1977 who received blood (n=87). If the hypothesized Hepatitis C infection rate of 10-15% is found, we plan to extend the study to examine the prevalence of Hepatitis C infection among the total cohort of 20 year-old very low birthweight subjects who received blood (n=198/156 seen at age 20). All subjects will be screened with the anti-HCV 3.0 enzyme immunoassay. We also plan to test for ALT as an indicator of ongoing hepatitis associated with HCV infection and for other transfusion-transmitted disease associated markers including HbsAg, anti-HBc and HIV. The pilot project will be implemented by initially sending a letter to the subjects who received neonatal blood transfusions informing them that they received blood as infants, that prior to 1986 blood was not screened for Hepatitis C, and that the Center for Disease Control suggests screening all persons who received blood transfusions prior to this time. Blood tests will be free of charge. Since the subjects were seen a year ago, the only additional information which will be required is an update on health and a question as to whether they ever received blood transfusions after the neonatal period. The subjects will be informed of the results, and if positive for Hepatitis C they will be referred for counseling and further testing for potential liver disease.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print.

Comparison of Two Rapid Whole-Blood Tests for Helicobacter pylori Infection in Chinese Patients. by Leung WK, Chan FK, Falk MS, Suen R, Sung JJ.; 1998 Nov; http://www.pubmedcentral.gov/articlerender.fcgi?tool=pmcentrez&artid=105355
The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with blood tests, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “blood tests” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for blood tests (hyperlinks lead to article summaries): •

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND BLOOD TESTS Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and blood tests.
Finding Nutrition Studies on Blood Tests The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “blood tests” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 4. PATENTS ON BLOOD TESTS Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “blood tests” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on blood tests, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Blood Tests By performing a patent search focusing on blood tests, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter.

Blood bank cuvette cassette and label therefor Inventor(s): Levy; Didya D. (Brooklyn, NY), Scordato; Richard E. (Scarsdale, NY) Assignee(s): Medical Laboratory Automation, Inc. (Mount Vernon, NY) Patent Number: 4,472,357 Date filed: November 18, 1981 Abstract: A plurality of cuvettes joined together by breakable links between each cuvette for use in testing blood for its ABO classification and the presence of a typical antibodies, and for crossmatching blood for compatibility, together with label means for indicating the reagents used in each cuvette and the identity of the person whose blood is being tested. The cuvettes may be adapted to accept a closure means which permits the cuvettes to be pre-packaged with reagents required to carry out blood tests. The cuvettes have a hydrophilic polymer coating thereon that is non-destructive of red blood cells. Excerpt(s): This invention relates to cuvettes used in a blood processing center for typing blood according to the ABO classification system, for screening the blood to identify atypical antibodies, and for crossmatching the blood for compatibility with that of potential donors. The invention also relates to an indicia means for positively identifying the cuvettes both as to the reagents used therein for carrying out the aforesaid procedures and the person whose blood is being classified. The importance of error free classification of a patient's blood and a donor's blood when the latter is to be transfused to the patient is so well understood by those working in the field of blood banking that it need not be reiterated here other than to say that transfusion of incompatible blood to a patient can lead to severe hemolytic reactions and even to the death of the patient. This incompatibility arises from the fact that red blood cells vary in their structure by what are called antigens so that one person's blood cells may have certain antigens that differ from those carried by the red blood cells of another person. If foreign antigens are introduced into a person's blood stream, his immunological system immediately produces antibodies that destroy the foreign material, i.e., the introduced blood cells carrying the foreign antigen. The incompatibility may also arise from the donor's serum which may contain antibodies that would destroy the patient's red blood cells because of the antigens carried thereon. Therefore, every effort must be made to facilitate the proper classification of blood and to properly and positively identify the classified blood so that incompatible blood transfusions are avoided. The principal blood cell antigens are designated A and B, with some cells having A antigens, some having B antigens, some having both A and B antigens, and some having neither A nor B antigens. Thus, blood having red cells carrying A antigens is referred to as Type A blood, that having cells carrying B antigens as Type B blood, that having cells carrying both A and B antigens as Type AB blood, and that having cells which do not carry either antigen as Type O blood. Other antigens are important, such as the D and other Rh antigens. The ABO blood group is generally determined by a forward typing protocol in which a person's red cells are mixed with antiserum reagents containing known antibodies to see if agglutination takes place. Thus, red cells are mixed with anti-A serum, anti-B serum, anti-AB serum, and anti-D serum. If the mixture of anti-A serum and the patient's red cells agglutinate and the mixture of anti-B serum and red cells does not, the patient's blood group is Type A. That is, the patient's red cells carry the A
Patents 65
antigen. If the reverse result obtains, then the patient' s blood group is Type B. In both of these instances, the anti-AB mixture would agglutinate. If agglutination occurs in both mixtures, and in the anti-AB mixture, the blood group is Type AB, and if agglutination is absent in all mixtures, the blood group is Type O. If the D antigen is present, i.e., the anti-D serum-cell mixture agglutinates, the blood group is positive, e.g., Type A+, and if the D antigen is absent (when the mixture does not agglutinate) the blood group is negative, e.g., Type B-.

Blood test for assessing hepatic function Inventor(s): Wagner; David A. (Nashua, NH), Woolf; Graham M. (Los Angeles, CA) Assignee(s): Metabolic Solutions, Inc. (Merrimack, NH) Patent Number: 5,928,167 Date filed: October 20, 1997 Abstract: Provided herein is a novel blood test for assessing hepatic function. The test involves administration of a labeled methionine or methionine metabolite to a subject and measurement of the expired label in blood. Excerpt(s): The present invention relates to a method for monitoring hepatic disease or dysfunction. More specifically, the invention relates to administering labeled methionine or methionine metabolites to an individual and assessing labeled carbon dioxide in blood. Standard serologic and biochemical serum liver tests have been used to determine the presence of liver disease. However, these tests do not provide an accurate assessment of hepatic functional capacity nor do they detect changes in hepatic disease severity (Gitnick, G. Surg. Clin. N. Am. 61:197-207 ›1981!). Increasing prothrombin time and decreasing serum albumin concentrations have been used as prognostic indicators of progressive liver disease (Rydning, A., et al. Scand. J. Gastroenterol. 25:119-126 ›1990!). Significant changes in prothrombin time and albumin may occur in patients for reasons other than liver dysfunction and, at times, only after severe liver decompensation. Further, radiological testing and histological examination of liver biopsies are poor indicators of decreasing hepatic function. The Child-Pugh (CP) classification is used to determine the degree of liver disease severity. The CP classification reflects the sum of scores derived from clinical and laboratory parameters. Disadvantages of the CP classification include subjective measures (degree of ascites and encephalopathy) and dependence on serum tests (bilirubin, albumin, and prothrombin time) that may be influenced by extrahepatic factors. As a result, the CP classification is a poor measure of patient status and is insensitive to small changes in the patient's condition. Web site: http://www.delphion.com/details?pn=US05928167__

Blood Tests
Abstract: A blood test strip includes a support member having an upper surface and lower surface. A separating member is disposed on the upper surface of the support member, and includes an upstream end and a downstream end. A recipient member is disposed on the upper surface of the support member in a side by side relation to the separating member. The recipient member includes an upstream end disposed in an adjacent, non-interwoven relation to the downstream end of the separating member to define an incision therebetween. Excerpt(s): The present invention relates to methods and devices for the testing of blood constituents, and more particularly to a blood test strip, and a method of using a blood test strip to prepare a blood sample for analysis. In recent years, there has been a marked increase in the awareness of health issues. One manifestation of this awareness is that an increased importance is being placed on the use of preventive medicine to maintain good health. The widespread adoption of preventative medicine has resulted in an increase in the frequency of the testing for certain conditions, such as abnormal glucose and cholesterol levels, which indicate the existence of a disease, or the propensity to acquire a disease or disorder. The monitoring and detection of these conditions often is performed by analyzing a patient's blood to determine whether a particular substance exists in the patient's blood, or to determine the amount of that substance in a patient's blood. As a consequence of this increased monitoring, blood tests are being performed on a more frequent basis. Formerly, these tests were usually performed in large hospital or independent laboratories, for only large laboratories performed a sufficient volume of tests to justify the large expenditures often required for sophisticated laboratory equipment.

Blood test ware and matrixes Inventor(s): Anraku; Hideo (Shinnanyou, JP), Isogawa; Hironobu (Shinnanyou, JP) Assignee(s): Sekisui Kagaku Kogyo Kabushiki Kaisha (Osaka, JP) Patent Number: 5,888,824 Date filed: July 5, 1996 Abstract: This invention has for its object to provide a blood component depositionpreventing agent and a blood coagulation accelerator, which are substantially indifferent to blood coagulation activity and serum chemistry parameters and a plastic blood test ware and a blood test matrix which do not confound measured values. The invention relates to a blood component deposition-preventing agent comprising a random copolymer of a monomer component (a) giving a water-soluble homopolymer and a monomer component (b) giving a water-insoluble homopolymer, a blood coagulation accelerator comprising a substantially blood-insoluble antimicrobial composition comprising a carrier and, as supported thereon, an antimicrobial metal, and a blood test ware or matrix carrying them on its inside wall or surface. Excerpt(s): The present invention relates to a blood component deposition-preventing agent and a blood coagulation accelerator for use in the laboratory examination of a blood sample, particularly in hematology, serum biochemistry, and immunoserology, methods using them, and blood examination ware and matrixes. With recent advances in testing techniques, the chemical, immunoserological and hematological examinations of blood have witnessed a remarkable mechanization so that it is by now certain that only if properly prepared samples were provided, such examinations could be carried
Patents 67
through in short periods of time. For example, even in the outpatient setting, the doctor would be able to make a diagnosis based on blood examination data, thus contributing much to the diagnosis and therapy of diseases. As to the pretreatment for hematological examinations using whole blood as a sample, mere admixing of the blood with an anticoagulant, which is not time-consuming, is sufficient so that the sample can be almost immediately set in an analyzer.

Capillary tube holder for test instruments especially blood tests and particularly for platelet counters, with two coaxial chambers Inventor(s): Pierotti; Romano (Aiezzo, IT) Assignee(s): S.E.A.C.s.r.l. (IT) Patent Number: 4,738,827 Date filed: May 6, 1986 Abstract: The phial or vial holding for a capillary tube is internally subdivided into an external chamber having annular cross-section and an internal chamber having circular cross-section. The outer wall of the chamber of annular cross-section carries a capillary hole and the inner tubular wall separating the two chambers has a hole in alignment with that of the outer wall and of larger diameter. In the hollow space of annular crosssection, a slight entrained flow through the hole of the inner wall and consequently a fast removal of the sample liquid which has passed through the capillary hole takes place. This is without backward flow in the direction of the capillary hole. Excerpt(s): This invention relates, in general, to holders and, in particular, to a new and useful holder for capillary tubes and phial holders. The invention refers particularly to a phial or vial for holding capillary tubes that are intended for use with biomedical test instruments and in particular for certain blood tests requiring the counting of cells present in suitably diluted blood. This is particularly but not exclusively, for the counting of thrombocytes or platelets. The basic concept of the present capillary tube holder involves the evaluation of the difference of electrical characteristics which occur within the capillary port or hole upon the passage of a body contained in the sample that is to be counted. The main problem is that of avoiding or at least limiting the error which may occur upon a possible passage of an already counted body--and which has therefore already passed through the capillary tube--in the vicinity of the same capillary tube, which event may cause an electrical signal corresponding to that taking place upon a passage of a body and, hence, may lead to a mistaken count of a further particle. According to the invention, the phial for holding capillary tubes, or capillary tube holder, is internally subdivided into an external chamber having an annular crosssection and an internal chamber having a circular cross-section most coaxial therewith. The outer wall of the chamber, which has an annular cross-section, carries the capillary port or hole and the inner tubular wall separating the two chambers has a hole disposed in alignment with that of the external capillary hole. The inner hole has a larger diameter than the outer capillary hole. Through suction, the sample liquid is made to enter inside the test tube of the platelet counter through the capillary hole. Soon after its transit into the capillary hole, the sample liquid goes through the annular hollow space and passes through the hole of large diameter, into the tubular inner wall to reach the internal chamber. Inside the hollow space having the annular cross-section, a slight call flow is thus generated through the hole of the tubular inner wall, said flow causing a fast removal of the sample liquid that has gone through the capillary hole with no

backward flows in the direction of the outer capillary hole but with relatively very fast transit within the internal chamber defined by the tubular wall and having circular cross-section. Web site: http://www.delphion.com/details?pn=US04738827__ •
Device for testing fluids Inventor(s): Rayman; Gerard A. (10 Sternes Way, Stapleford, Cambridge, GB) Assignee(s): none reported Patent Number: 5,004,584 Date filed: June 23, 1988 Abstract: Blood tests are made using a diagnostic stick which has a testing chamber at one end of the stick. The chamber has an open end and is dimensioned so that blood can be drawn in to fill the chamber by capillary action. A testing surface is either mounted in the chamber or is on a separate probe which can be immersed in blood in the chamber. The invention can be used with fluids other than blood. Excerpt(s): This invention relates to a device for testing fluids. The device is particularly useful for testing body fluids, especially blood, and it allows blood testing to be carried out simply, quickly, and hygienically. Certain blood tests are conventionally carried out using a diagnostic stick which carries a testing surface having a culture medium or chemical reagent on it. Sticks with an electrochemical testing surface are also known. Blood to be tested is brought into contact with the testing surface and it is important that precise coverage of the testing surface is achieved, i.e. that the whole of the surface is evenly brought into contact with the blood to be tested. According to the present invention, there is provided a fluid testing device which has a chamber having an opening at one end, the chamber being adapted to be filled through capillary action when the opening is placed in a fluid, and a testing surface associated with the chamber and adapted to react to fluid in the chamber to produce an indication of properties of the fluid.

Electronic instrument for the control and treatment of infertility in women Inventor(s): Crausaz; Jacques (Fribourg, CH), Nessi; Pierre (Geneva, CH) Assignee(s): Ares N.V. Amsterdam NL, Swiss Branch (Geneva, CH) Patent Number: 4,530,366 Date filed: November 23, 1982 Abstract: A micro-computer-based instrument for characterizing a woman's menstrual cycle by measuring her temperature (BBT) each day and storing and analyzing those temperatures. The instrument defines, with user interaction, a time window each day during which it will accept a temperature measurement within a predetermined acceptable temperature range taken with the aid of a thermistor temperature probe than can be placed under the woman's tongue. The analysis carried out on the collected temperature data includes comparing, from the eighth day of a cycle, two average temperatures: M.sub.F (average of a presumed follicular phase) and M.sub.L (average of a presumed luteal phase). Comparison continues until the difference between M.sub.L
Patents 69
and M.sub.F exceeds a predetermined level thereby defining a second phase of the cycle indicating that ovulation has occured. After characterizing the cycle, the instrument indicates the most appropriate days for hormone treatment, blood tests and physician visits so that fertility treatment can be optimized. Excerpt(s): This invention relates to an electronic instrument for measuring and analyzing a woman's basal bodily temperature (BBT) in connection with the treatment of infertility. A normal menstrual cycle of a fertile woman is characterized by basal body temperature (BBT) curve that is biphasic, i.e., there is a rise in temperature a few hours after ovulation, a rise which generally occurs at about the middle of the menstrual cycle. In cases of infertility the BBT curve is frequently abnormal. For this reason a gynecologist usually begins the investigation of an infertile patient by analyzing 2 or 3 cycles of the BBT.

Fecal occult blood test Inventor(s): Lawrence; Paul J. (2082 Abbey La., Campbell, CA 95008) Assignee(s): none reported Patent Number: 4,615,982 Date filed: December 11, 1984 Abstract: Fecal occult blood tests of enhanced sensitivity and specificity are provided by employing (1) a developer composition comprising a solution of a hydroperoxide in a solvent comprising at least about 50% by volume of a solvent for iron protoporphyrins such as dimethyl sulfoxide and/or (2) a solid test matrix comprising a solid support impregnated with a leuco dye and a hemoprotein solubilizing agent. Test results may be further improved by incorporating plant peroxidase inhibitors, iron/copper chelating agents and buffers in the developer and/or test matrix. Excerpt(s): This invention is in the field of fecal occult blood tests (FOBT). More particularly it relates to improved FOBT that provide a reduced incidence of false results and/or greater sensitivity and specificity. U.S. Pat. No. 3,996,006 describes a FOBT technique that popularized the guaiac-based test for occult blood in feces. It employs a slide having a sheet of guaiac-impregnated paper between a front panel and a rear panel with openings in the panels and pivotal flaps to cover the openings. A fecal specimen is placed on the paper through the opening in the front panel and that panel is closed. The rear panel is then opened and a hydrogen peroxide developer is placed on the paper via the opening in the rear panel. If blood is present in the specimen, the paper will turn blue. A commercial embodiment of this test, called the HEMOCCULT.RTM. test, is widely used in hospitals and physicians' offices. Despite the widespread popularity of the HEMOCCULT.RTM. test recent studies have pointed out serious limitations in its sensitivity and specificity. Applicant believes that the sensitivity limitation is due partly to (1) the fact that hemoglobin in many specimens is degraded to hemoproteins that exhibit little or no peroxidative activity, (2) degradation of peroxidatively active hemoproteins by the hydroperoxide reagent used in the test and (3) relative insolubility of the degraded products (i.e., iron protoporphyrins such as heme and hemin) in the reagents used in the test. Sensitivity limitations, of course, may cause false negative results. The specificity limitation is probably due to the response of the test to plant peroxidases and/or iron or copper in the specimens or the environment in which the test is run. Specificity limitations lead to false positive results. U.S. Pat. No. 4,333,734

Blood Tests
describes a variation in the guaiac-based FOBT that is intended to reduce the incidence of false positive results due to the presence of plant peroxidases in the specimen. It includes a peroxidase denaturing agent such as urea or guanidine hydrochloride together with a metal chelating agent to sequester calcium and magnesium ions that are essential to peroxidase activity. The denaturant and the chelating agent are formulated with the guaiac. Web site: http://www.delphion.com/details?pn=US04615982__ •
Fecal occult blood test product with positive and negative controls Inventor(s): Burrows; Janine P. (Orange, TX), Guadagno; Philip A. (Vidor, TX) Assignee(s): Helena Laboratories Corporation (Beaumont, TX) Patent Number: 5,196,167 Date filed: May 9, 1991 Abstract: A test sheet for the determination of the presence of a substance having peroxidase-like activity in a throw-in-the-bowl fecal occult blood test, includes a specimen test area and a positive control area. The test area has deposited thereon a test ink having at least one oxygen donor reagent and a chromogen reagent capable of being oxidized by the oxygen donor in the presence of blood or a substance having peroxidase-like activity, to provide a visually observable change of color. The test ink also includes a water soluble polymer for immobilizing the chromogen and oxygen donor. The positive control area has deposited thereon the test ink and a substance having the peroxidase-like activity. Excerpt(s): The present invention relates generally to an occult blood test product, of the type to be physically placed into a toilet bowl containing a fecal specimen, for detecting the presence of fecal occult blood in an aqueous solution. More particularly, the present invention relates to an improved, reliable fecal occult blood test product which may be utilized with a minimum of human intervention. The principles of the present invention may be employed in the testing for occult blood, ferritin and myoglobin in various biological fluids. In general terms, the testing of a fecal specimen for occult blood is based on the well-known principle that blood (more particularly hemoglobin) will function as a catalyst and cause oxygen to be liberated from an oxygen donor, with the liberated oxygen thus causing a color change in a chromogenic substance. As such, the test for fecal occult blood is not only well-known, but numerous oxygen donors, numerous chromogens and numerous donor-chromogen pairs have been suggested in the prior literature. In considering the chromogens and oxygen donors which may be used, it should be appreciated that the fecal occult blood test is frequently referred to as a test for the presence of a substance having a peroxidase-like activity. In addition, there are several principle styles of fecal occult blood test products which have been marketed or described in the literatures. These include slides, tape, wipe and throw-inthe-bowl products. Slide products require the patient to retrieve part of the stool specimen and, using a spatula or equivalent device, place part of the specimen on a paper which paper is thereafter submitted to a laboratory where a developing solution is applied to the slide. Tape products are typically utilized by a physician after a rectal examination in which instance the physician smears a stool sample on a thin, narrow tape and then a developing solution is applied to the tape. In both of these types of products, the chromogen is guaiac, and the oxygen donor or developing solution is hydrogen peroxide.

Glucose monitor calibration methods Inventor(s): Gross; Todd M. (Saugus, CA), Mastrototaro; John J. (Los Angeles, CA), Shin; John J. (Glendale, CA) Assignee(s): Medtronic Minimed, Inc. (Northridge, CA) Patent Number: 6,424,847 Date filed: February 23, 2000 Abstract: A method of calibrating glucose monitor data includes collecting the glucose monitor data over a period of time at predetermined intervals. It also includes obtaining at least two reference glucose values from a reference source that temporally correspond with the glucose monitor data obtained at the predetermined intervals. Also included is calculating the calibration characteristics using the reference glucose values and the corresponding glucose monitor data to regress the obtained glucose monitor data. And calibrating the obtained glucose monitor data using the calibration characteristics is included. In preferred embodiments, the reference source is a blood glucose meter, and the at least two reference glucose values are obtained from blood tests. In additional embodiments, the calculation of the calibration characteristics is obtained using linear regression and in particular embodiments, least squares linear regression. Alternatively, the calculation of the calibration characteristics is obtained using non-linear regression. Excerpt(s): This invention relates to glucose monitor systems and, in particular embodiments, to calibration methods for glucose monitoring systems. Over the years, body characteristics have been determined by obtaining a sample of bodily fluid. For example, diabetics often test for blood glucose levels. Traditional blood glucose determinations have utilized a painful finger prick using a lancet to withdraw a small blood sample. This results in discomfort from the lancet as it contacts nerves in the subcutaneous tissue. The pain of lancing and the cumulative discomfort from multiple needle pricks is a strong reason why patients fail to comply with a medical testing regimen used to determine a change in a body characteristic over a period of time. Although non-invasive systems have been proposed, or are in development, none to date have been commercialized that are effective and provide accurate results. In addition, all of these systems are designed to provide data at discrete points and do not provide continuous data to show the variations in the characteristic between testing times. A variety of implantable electrochemical sensors have been developed for detecting and/or quantifying specific agents or compositions in a patient's blood. For instance, glucose sensors are being developed for use in obtaining an indication of blood glucose levels in a diabetic patient. Such readings are useful in monitoring and/or adjusting a treatment regimen which typically includes the regular administration of insulin to the patient. Thus, blood glucose readings improve medical therapies with semi-automated medication infusion pumps of the external type, as generally described in U.S. Pat. Nos. 4,562,751; 4,678,408; and 4,685,903; or automated implantable medication infusion pumps, as generally described in U.S. Pat. No. 4,573,994, which are herein incorporated by reference. Typical thin film sensors are described in commonly assigned U.S. Pat. Nos. 5,390,671; 5,391,250; 5,482,473; and 5,586,553 which are incorporated by reference herein. See also U.S. Pat.

Blood Tests
Method and apparatus for non-destructive screening of specimen integrity Inventor(s): Jacobs; Merrit Nyles (Fairport, NY), Samsoondar; James (Cambridge, CA) Assignee(s): CME Telemetrix Inc. (Waterloo, CA) Patent Number: 6,353,471 Date filed: June 9, 1997 Abstract: A method and apparatus for providing a non-destructive pre-test screen of specimen integrity for a blood analyzer by measurement of absorbance or reflectance is provided. The method involves measurement of polychromatic light in the near infrared and adjacent visible region, which is either transmitted or reflected from a specimen as presented for measurement, and correlation of the measurement, on the basis of predetermined algorithms, to the quantity of a known substance contained in the sample. The apparatus employs a spectrophotometer which emits radiation which is split into a beam which passes to a sample and a reference beam, the beam returning from the sample and the reference beam are variably combined and further separated into various components by means of a grating and focused onto a linear array detector. A microprocessor receives output from the array detector and performs calculations of concentration(s) of the known substance(s). The invention provides quality assurance for state-of-the art blood analyzers and automated laboratories by pre-screening serum and plasma integrity, even where labels on the sample container would normally interfere with a quality assurance assessment, identifying samples not suitable for certain blood tests, or, if tests are conducted on specimens with compromised integrity, the pre-screening results will aid in the interpretation of the test results. Excerpt(s): This invention relates to spectrophotometry and the spectrophotometric analysis of blood samples. In particular, this invention relates to a method and apparatus for providing a non-destructive pre-test screen of specimen integrity for a blood analyzer by measurement of absorbance or reflectance. Clinical laboratory tests are routinely performed on the serum or plasma of whole blood. In a routine assay, red blood cells are separated from plasma by centrifugation, or red blood cells and various plasma proteins are separated from serum by clotting prior to centrifugation. Haemoglobin (Hb), bilirubin (Bili) and light-scattering substances like lipid particles are typical substances which will interfere with, and affect spectrophotometric and other blood analytical measurements. Such substances are referred to as interferents. Elevated Bili can be due to disease states, and increased lipid particles in the blood, also known as hyperlipidemia, can be due to disease states and dietary conditions. Elevated Hb in the blood, hemoglobinemia, can be due to disease states and as a result of specimen handling. Clinical laboratories currently emphasize these three potential interferents as being of greatest concern with respect to affecting blood analysis. Biliverdin, (BV), a fourth potential interferent, is rarely mentioned. Web site: http://www.delphion.com/details?pn=US06353471__

Method for preventing blood denaturation and blood test tool to be used therein Inventor(s): Higashino; Kouji (Kyoto, JP), Nishimura; Satoshi (Kyoto, JP) Assignee(s): Arkray, Inc. (Kyoto, JP) Patent Number: 6,379,318 Date filed: May 11, 2001
Patents 73
Abstract: A blood test tool with which blood in a dried state can be held without denaturation. In the blood test tool wherein a card made of filter paper is impregnated with the blood and then the blood is held in a dried state, a carboxylic acid such as citric acid is added to the part for holding blood. Thus, the carboxylic acid exerts an effect of preventing the blood in the dried state from denaturation. It is preferable to add a nonreducing sugar (sucrose, etc.), an anticoagulant (EDTA, etc.) and an antioxidant (glutathione, etc.) together with the carboxylic acid. This blood test tool can be produced by impregnating a filter paper card with a solution containing citric acid, etc. dissolved therein and then air-drying. Excerpt(s): The present invention relates to a method for preventing the denaturation of blood, particularly hemoglobin, and a blood test tool to be used therein. Hemoglobin Alc (HbAlc) in which hemoglobin (Hb) is bonded to glucose reflects the average glucose level of the body one or two months earlier. Therefore, it is widely used in physical examinations for geriatric diseases or treatment and consultation therefor. However, since it takes a long time to measure HbAlc, for example, even if the blood is collected from outpatients when they visits to hospital, the result of the examination of HbAlc is generally evaluated when the patient visits to the hospital the next time. Therefore, although the measurement value of HbAlc is an important factor for diagnosis of diabetes, actually, it has not been used effectively for treatment. To solve this problem, a blood collection card made of filter paper has been proposed ("Diabetes" Vol. 38, No. 10 (1995), JP10-104226A, etc.). The patients collect blood onto the collection card by themselves and allow the collection card to be impregnated with the collected blood, dried, and then mail the card to the hospital. In the hospital where this card is received, the part impregnated with the blood of the card is cut out or punched out (punch-out), and then blood is eluted therefrom. The eluted blood is examined for the predetermined items including HbAlc, etc. When the patient visits to the hospital, the treatment or diagnosis is performed based on the examination results.

(Duesseldorf, DE), Thiel; Eckard (Berlin, DE) Assignee(s): Rhein Biotech Gesellschaft fur Neue Biotechnologische Prozesse und Produkte (DE) Patent Number: 6,521,460 Date filed: February 8, 1999 Abstract: The present invention relates to a method of carrying out blood tests. The invention is based on the finding that clinico-chemical blood parameters can be determined using not only blood serum but also blood plasma. Therefore, freshly taken blood samples, which are mixed with at least one thrombin inhibitor, can be used for determining both clinico-chemical parameters and hematological parameters. The clinico-chemical parameters can thus be determined using blood plasma, a separation of coagulable components being not required any more. Excerpt(s): The present invention relates to a method of carrying out blood tests. Many diverse blood tests are required for diagnosing, in particular, internal diseases and for controlling the course thereof. These blood tests can be divided into tests regarding the cellular blood components (blood count, differential blood count, blood group,

immunophenotyping of blood cells) and into serum tests and also into antibody screening tests, Coombs tests and cross-matching tests. Serum tests are concerned with the determination of enzymes, metabolic products (e.g. creatinine, urea, blood sugar) and coagulation parameters. In addition, special tests, such as hormone analyses or drug level analyses, are carried out on the basis of serum. With seriously ill and hospitalized grown-up patients, enlarged blood tests have to be carried out over a prolonged period of time every day and sometimes even twice a day to detect critical changes in the physical condition of the patient at an early stage. Blood is taken under sterile conditions normally using a closed blood taking system by puncturing a vein in the bend of the elbow (e.g. V. cubita mediana). Blood is optionally taken through already laid central indwelling catheters. Depending on the clinical requirements and the desired laboratory tests, types and numbers of the tubes to be filled with blood are defined. Specific laboratory tests can only be carried out with specific substances specifically prepared for such tests (e.g. specific anticoagulants (heparin, EDTA, citrate, etc.)) or with glucosidase inhibitor ("blood sugar tubes") or blood withdrawing tubes containing coagulation-promoting substances ("serum tubes"). Heparin and EDTA are unspecific, indirect inhibitors. They do not act directly or specifically on a specific element of the blood coagulation cascade, but their effect is of an indirect nature in that they intercept, for example, Ca.sup.2+ ions which, in turn, are essential for the activation of different proteins of the coagulation system. A uniform pretreatment of the blood to be tested ("standard tube"), on the basis of which all or at least the majority of important blood tests could then be carried out, does not exist. Furthermore, it follows from the standard logistic sequence in clinico-chemical or hematological laboratories that a plurality of blood withdrawal tubes that have been pretreated in the same way are often needed. After withdrawal from the patient, and depending on the laboratory values to be determined, the blood tubes are transferred into laboratories that are most of the time separated spatially (most of the time a clinico-chemical laboratory and a hematological laboratory and optionally laboratories for special tests, such as immunophenotyping, drug level in the serum, etc. (material dispatch by mail or courier might here be necessary). The blood tubes received in the laboratory must first be sorted, and the tubes to be centrifuged are then centrifuged at about 3,500 r.p.m. for five minutes. The blood taking tubes are then forwarded to the different work places (coagulation tubes to the coagulation place, serum tubes for electrolyte determination on the flame photometer, etc). The respective automatic analyzing devices are then loaded with the samples, with the sample volume of about 10.mu.l to 100.mu.l, which is needed for one measurement, being very small in most measuring operations. The actual measuring operation lasts from a few seconds to a few minutes (five minutes at the most, depending on the method and the device). The measured values are finally printed out and, depending on the origin, are communicated in writing to the dispatching stations. Web site: http://www.delphion.com/details?pn=US06521460__ •
Occult blood test monitor Inventor(s): Oksman; Norman H. (Mountain Lakes, NJ), Talmage; Joseph M. (Landing, NJ) Assignee(s): Warner-Lambert Company (Morris Plains, NJ) Patent Number: 4,675,160 Date filed: January 28, 1986

Abstract: An in-the-bowl occult blood test is provided with a flushable matrix having a separate testing site which will indicate the presence of residual oxidizing compounds in the toilet. Excerpt(s): This invention relates to a testing monitor useful for detection of peroxidaselike activity and, in particular, a test kit for detection of such activity in stool samples containing a testing monitor. The detection of peroxidase-like activity was found to be indicative of the presence of hemoglobin in a specimen and, reported to be correlated to the heightened fertility period in females during the estrous cycle. The detection of peroxidase-like activity has, therefore, become an invaluable aid to the medical practitioner. Over 100,000 persons in the United States are affected by cancer of the colon and rectum each year. When the number of colorectal cancers occurring each year is combined with the number of cancers occurring in other digestive organs, including the esophagus and stomach, such cancers of the digestive system account for more occurrences of cancer than any other single form of the disease.

Reminder device for blood self-testing Inventor(s): Cota; Joseph A. (Apt #1, No. Andover, MA 01845) Assignee(s): none reported Patent Number: 6,024,723 Date filed: March 4, 1999 Abstract: A device is described for reminding a patient suffering from ailments such as diabetes and high cholesterol levels, who performs daily blood tests, of the site of the last blood extraction, in the case where blood is drawn from one or more sites of each finger of the hands. The invention includes two disks, each having an inner face and an outer face, the inner face containing a representation of the opposite hand from the other. On each disk finger holes are punched in the vicinity of the fingers to represent the sites where blood is drawn. On the inner face of each disk is a red marker area which may be displayed under the finger hole on the opposite disk, corresponding to the last site where blood was drawn. When the user progresses from one hand to the other in his testing regime, the device is flipped over, and the outside face of the other disk is used to display the status of the site where blood has been drawn on a representation of the hand currently used. Excerpt(s): The present invention relates to medical reminder devices, and more specifically to reminders used in connection with the drawing of blood for self-testing by patients suffering from ailments such as diabetes and high cholesterol levels. Millions of people suffer from diabetes in the United States alone. Many of these patients are required to draw blood on a daily basis, and do test the blood themselves in order to assure the chemical balance of their systems, which is essential to their well-being. Drawing of the blood involves puncturing the skin in the region where blood will flow freely and profusely. The fingers of the hands are generally chosen as appropriate for the sites of blood extraction. Web site: http://www.delphion.com/details?pn=US06024723__

Blood Tests
Test tube for biological analyses, provided with a device for checking efficiency and position, for photometric readings Inventor(s): Pratellesi; Tiziano (Pontassieve, IT), Ricci; Antonio (Monteriggioni, IT) Assignee(s): Diesse Diagnostica Senese S.r.l. (Milan, IT) Patent Number: 5,244,637 Date filed: January 8, 1992 Abstract: Test tube for biological analyses, and in particular for blood tests such as erythrocyte sedimentation rate, provided with a device making it possible to perform a photometric inspection of the test tube with a relative movement between the optical system and the test tube (1), the latter being between the emitter (E) and the receiver (R) of said system; the test tube possesses--externally on the base--a device in the form of an optical prism (5) that induces a sudden change in the direction of the light beam emitted by the emitter so that it briefly is unable to reach the receiver. Excerpt(s): The invention relates to a test tube for biological analyses and in particular for blood tests, for example measuring the erythrocyte sedimentation rate (or E.S.R.) and other tests and analyses that can be performed with optical measuring instruments. With equipment of this kind, use is generally made of test tubes that may be of various shapes and sizes. To achieve a good level of automation and eliminate all sources of error, it is advisable to carry out a number of checks, especially checking that test tubes are present and that they have been correctly positioned in the instrument. In addition, it is always advisable to check the efficiency of the optical systems (emitter+receiver), so that errors of insertion and position of the test tubes are not inadvertently made. In the present invention, the check for the presence of the test tube can in fact be made directly by the instrument's optical reading system and suitably controlled by a computer. The device of the invention also serves to check on the exact position of the test tube inside the instrument, since a test tube that is not fully inserted in its seat can--if the fault is not reported--give rise to bad data readings which may then cause sometimes very serious problems and errors. Another useful aspect of the invention is that it can automatically carry out a continuous and repeated check on the speed and inertia of response of the optical sensor, so as to avoid errors in the readings and in the results obtained from these.

Treatment of human plasma with brown recluse spider toxin to emulate a lupus anticoagulant Inventor(s): Babcock; James L. (San Antonio, TX), McGlasson; David L. (San Antonio, TX) Assignee(s): The United States of America as represented by the Secretary of the Air (Washington, DC) Patent Number: 4,877,741 Date filed: October 24, 1988 Abstract: A new method for improving the accuracy of blood tests for the presence of lupus anticoagulants and for blood factor deficiencies is disclosed. Brown recluse spiders are collected, their venon glands removed by microdissection and the active toxin extracted. The toxin is mixed with normal donor plasma in concentrations of about
Patents 77
3.5.mu.l/ml of toxin to plasma. The treated plasma successfully mimics human plasma having lupus anticoagulants. By using the treated plasma in blood tests and assays as a standardized control to which the results from tests on questioned blood plasma samples may be compared, the equipment and procedures for those tests may be calibrated and test results made more sensitive and reliable. Excerpt(s): The present invention relates generally to medical testing methods, and more specifically to the use of a brown recluse spider (Loxosceles reclusa) toxin treated human plasma as a positive control, or standardized reference, for lupus anticoagulant blood tests. Lupus anticoagulants are antibodies that interfere with blood coagulation, or clotting. Curiously, they are anticoagulants only in vitro, or outside the human body. In vivo, or inside the body, they act to increase the risk of thrombosis, or detrimental blood coagulation inside the heart, arteries, veins or capillaries. Lupus anticoagulants are found in the blood of many persons, and not merely in the blood of persons suffering from systemic lupus erythematosus, an inflammatory autoimmune disorder from which lupus anticoagulants derive their name. While persons having lupus anticoagulants present in their blood often show no adverse symptoms, a significant percentage of such persons will suffer from such complications as thrombosis, seizure disorders and, in women, spontaneous abortions. Unfortunately, testing blood for the presence of lupus anticoagulants is very inexact. Present tests or assays used for detecting lupus anticoagulants, which generally test in vitro for various impaired coagulation indicators, can give misleading results from, for example, the presence of mild blood factor deficiencies. Blood factors are contributors to beneficial blood clotting and a deficiency in any one of many such factors will reduce clotting both in vivo and in in vitro tests so that they can produce, in vitro, the same test results as lupus anticoagulants. Vice versa, a mild blood factor deficiency may be misdiagnosed as the presence of a mild lupus anticoagulant. To most accurately test blood plasma samples for lupus anticoagulants, a standardized positive control is required for calibration and comparison of both testing equipment and technique. Because blood plasma with a lupus anticoagulant is not easily stored, and because patients with a lupus anticoagulant for obtaining blood samples are not always convenient, there is a need for a commercially available control plasma that accurately mimics the effects of a lupus anticoagulant in human plasma for laboratory testing. Without such a positive control, laboratory technicians cannot be certain that their testing for the presence of lupus anticoagulants is indeed performed in a manner consistent with expected results.

member. Therefore, such a urine occult blood test enables to confirm which is bleeding, the right or left kidney or the right or left ureter. Excerpt(s): The present invention relates to a urine occult blood test apparatus for detecting bleeding from a urinary tract, especially bleeding from an upper urinary tract. Reaction paper for inspecting presence or absence of urine occult blood has been available on the market. This reaction paper is directly immersed in a urine sample to ascertain presence or absence of urine occult blood in the sample. In the conventional method of dipping the known reaction paper directly in the sampled urine, it is detectable whether or not occult blood exists in the urine discharged from a bladder. However, it is impossible to ascertain which is responsible for bleeding, the right kidney, the left kidney, the right ureter or the left ureter which supply urine into the bladder.

Cardiovascular imaging and functional analysis system Inventor(s): Bishop, Harry; (Bridgeport, WV), Majewski, Stanislaw; (Yorktown, VA), Umeno, Marc M.; (Cleveland Heights, OH) Correspondence: Supervisor, Patent Prosecution Services; Piper Marbury Rudnick & Wolfe Llp; 1200 Nineteenth Street, N.W.; Washington; DC; 20036-2412; US Patent Application Number: 20020188197 Date filed: December 1, 2000 Abstract: A Cardiovascular imaging and functional analysis system and method employing a dedicated fast, sensitive, compact and economical imaging gamma camera system that is especially suited for heart imaging and functional analysis. The system uses a dedicated nuclear cardiology small field of view imaging camera, allowing image physiology, while offering inexpensive and portable hardware. In some variations, a basic modular design suitable for cardiac imaging with one of several radionucleide tracers is used. The detector is positioned in close proximity to the chest and heart from several different projections, allowing rapid accumulation of data for first-pass analysis, positron imaging, quantitative stress perfusion, and multi-gated equilibrium pooled blood tests. In one variation, a Cardiovascular Non-Invasive Screening Probe system provides rapid, inexpensive preliminary indication of coronary occlusive disease by measuring the activity of emitted particles from an injected bolus of radioactive tracer. Excerpt(s): The present invention relates to medical diagnostic and screening apparatuses and methods. Particularly, the present invention relates to non-invasive medical diagnostic and screening systems. Still more particularly, the present invention relates to non-invasive imaging and functional analysis systems for evaluating cardiac and cardiovascular health. Cardiac imaging and functional analysis is the largest single nuclear medical imaging application and represents the area of greatest unmet need in the prior art. This need is exemplified by the fact that historically, for 30%-50% of those stricken with coronary occlusive (artery) disease, the first symptom of the disease is death. This outcome has motivated considerable interest in developing diagnostic methods and apparatuses to detect the condition of coronary occlusive disease prior to the onset of fatal symptoms, and further to assist in the development and implementation of preventive measures. First-Pass Radionucleide Angiography (RNA) provides the clinician with patient information for improved patient management that is either difficult and/or costly to obtain using other technologies. The First-Pass RNA can provide unique qualitative and quantitative information about cardiac function such as regional ventricular wall motion just at the peak of maximum exercise stress, left and right ventricular ejection fraction, regional contractivity, and left to right shunt quantitation. Concurrently, improvements in software analysis of the diagnostic tests

Blood Tests
are being developed and implemented on a regular basis. However, medical instrument improvements have not kept pace with detector hardware enhancements such as pixellated scintillation crystals, and position-sensitive photomultipliers. Presently, the nuclear medicine health care sector can perform a first-pass RNA diagnostic protocol using the commercially available dedicated cardiac imager multicrystal scanner model SIM400 from Picker International of Cleveland, Ohio, or a single crystal Anger gamma camera. The single crystal Anger camera has numerous disadvantages when used for first-pass RNA related to its low count rate capability including pulse-pileup and low count density. A low-count density image limits the ability to define changes in wall motion. Improvements in defining wall motion are attained using the multicrystal high rate camera. Other factors influencing the image quality are the intrinsic system resolution, count density, and the target-to-nontarget ratio. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Devices and methods for reading and interpreting guaiac-based occult blood tests Inventor(s): Matusewicz, Richard Sergei; (San Jose, CA), Schoengold, Ronald Joseph; (Saratoga, CA), Schrier, Wayne H.; (Half Moon Bay, CA), Silzel, John Warwick; (Yorba Linda, CA) Correspondence: Beckman Coulter Inc; 4300 North Harbor Boulevard; P O Box 3100; Fullerton; CA; 928343100 Patent Application Number: 20020136436 Date filed: February 23, 2001 Abstract: A medical analysis system for reading and interpreting an occult blood test (OBT) device is provided. The instant system comprises an image sensor for capturing an image of the entire test area of the FOBT device and for converting the image into a digital data. The system further comprises a data processor conventionally coupled to the image sensor. The data processor compares the digital data with pre-determined threshold conditions of a positive FOBT by utilizing a spectrographic and morphologic image analysis algorithm and determines a presence of the occult blood in the sample. A hue angle analysis for data processing may be used. A method of performing a FOBT on a sample is also provided. Excerpt(s): The present invention relates to determining the presence of occult blood in fecal matter, and more particularly to a system for reading and interpreting guaiacbased occult blood tests. Each year, more than 130,000 Americans are diagnosed with colorectal cancer. Of those afflicted, an estimated 56,000 die--a death toll that ranks this cancer as the second highest, for women and men, among all types of cancers. Scientific evidence suggests that the majority of colon cancers arise from the evolution of normal mucosa progressing into adenomas and finally to adenocarcinomas. Adenoma removal correlates with a reduced risk of rectal carcinomas; analogously, the removal of adenomatous polyps, reduces the likelihood of colon cancer (U.S. Pat. No. 5,790,761). Unlike other forms of cancer, early diagnosis and treatment of colorectal cancer results in a high cure rate of more than 90%. If, however, the disease is not detected until the later stages, the cure rate drops drastically to 25% or less (U.S. Pat. No. 5,264,181). Thus, early detection of the disease is critical to successful treatment of colorectal cancer. Occult (hidden) blood in feces is an early sign of colorectal cancer, adenomas and polyps. It is undetectable to the naked eye, because the blood is present in minute amounts. Tests and procedures for detecting occult blood in fecal matter are wellknown. One of the most successful tests is offered by Beckman Coulter, Inc. (Fullerton,
Patents 81
Calif.) under the trademark HEMOCCULT.RTM. and disclosed in U.S. Pat. No. 3,996,006 issued to J. F. Pagano. Briefly, a thin smear of fecal matter is applied to one side of the guaiac paper. Then, a developing solution, such as hydrogen peroxide, is applied to the opposite side of the guaiac paper. If blood is present in the fecal matter, the guaiac reaction will color the paper blue. Recently, a similar but more sensitive test has been introduced under trademark HEMOCCULT.RTM. SENSA.RTM. by Beckman Coulter, Inc. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Home doctor system, blood capsule and injection appliance Inventor(s): Kisakibaru, Toshiro; (Tokyo, JP) Correspondence: Rader Fishman & Grauer Pllc; Lion Building; 1233 20th Street N.W., Suite 501; Washington; DC; 20036; US Patent Application Number: 20010005772 Date filed: December 21, 2000 Abstract: A subscriber of a home doctor center carries a physical condition-monitoring device. Physical condition data measured by the device is transmitted to a personal computer in the subscriber's residence, and then transmitted therefrom to the center via a contact path. Blood collected to the subscriber is sent to the center. The center analyzes the physical condition data and tests the received blood with an automatic test system. Based on analytic results of the physical condition data and results of blood tests, initial diagnosis of the subscriber is performed, and the subscriber is informed of the result of the initial diagnosis together with a corresponding advise. By close tie-up with a medial institute and an insurance institute, the center can early find diseases of subscribers, and by calculating premiums imposed to subscribers with reference to results of initial diagnosis, premiums can be reduced. Excerpt(s): This invention relates to a home doctor system, blood capsule and injection appliance. People's interests in healthcare are getting larger and larger. As a result, market of dietary facilities, healthcare food and healthcare appliances has recently expanded rapidly. In regard to dietary conjunction, there are tonometers, pedometers, body fat measuring devices, and so forth, available for private use. Regarding healthcare food, a huge variety of preparations are commercially available. However, these dietary facilities, healthcare food and healthcare appliances often have only weak medical support about their efficacies, and consumers cannot get valuable effects for expenses. Additionally, most of dietary facilities, healthcare food and healthcare appliances were sold as products, individually, and were far from the concept of systematic, continuous healthcare. On the other hand, along with developments of genetic engineering, some genetic diseases are now being specified by DNA decoding, but such data is not yet used for systematic healthcare.

Method and device to treat vulnerable plaque Inventor(s): Daum, Wolfgang; (Groton, MA), Doscher, Claas; (Hamburg, DE) Correspondence: Dorsey & Whitney Llp; Intellectual Property Department; 50 South Sixth Street; Minneapolis; MN; 55402-1498; US Patent Application Number: 20030139739 Date filed: January 10, 2002 Abstract: A method and device to treat cardiovascular vulnerable plaque is provided by heating an implanted structure placed adjacent to a vulnerable plaque tissue to conduct heat into the vulnerable plaque tissue for a period of time. In a preferred embodiment, the implanted structure is a stent-like structure (SLS), and the heating of the implanted structure is a non-invasive inductive heating. The detecting of the vulnerable plaque tissue can be accomplished by techniques, such as Magnetic Resonance Imaging (MRI), infrared spectroscopy, thermography, blood tests, ultrasound, and X-ray, etc. Excerpt(s): The present invention generally relates to cardiovascular medicine. More particularly, the present invention relates to a cardiovascular heat delivery device and a method to treat a vulnerable plaque tissue. Coronary artery disease (CAD) is the most important cause of morbidity and mortality in today's society. Atherosclerosis (the most common form of arteriosclerosis, marked by cholesterol-lipid-calcium deposits in arterial linings), "hardening" of the arteries caused by plaques and plaque lesions, is the cause of myocardial infarction (MI). Some plaques are "hard and solid", and the others are "soft and squishy". It's the soft variety that is to worry about. Recently, this soft plaque has been called "vulnerable plaque" because of its tendency to burst or rupture. Ischemic heart disease represents a continuum from stable angina to unstable angina to non-Q-wave MI to Q-wave MI. Patients whose angina becomes unstable are classified as having acute coronary syndrome (ACS). It was formerly believed that thrombosis leading to critical occlusion of coronary arteries at the site of atherosclerotic plaque rupture was the common cause of ischemic heart disease. It is now thought, that even plaque lesions that do not critically occlude coronary arteries can cause MI. ACS can be caused by the rupture of an unstable atherosclerotic plaque. Vulnerable plaques are usually those causing only mild to moderate stenosis and having a lipid-rich core and a thin, macrophage-dense, collagen-poor fibrous cap. Factors affecting plaque rupture include mechanical injury, circadian rhythm, inflammation, and infection. Progressive thrombosis and vasospasm may follow plaque rupture.

The objects are achieved by a blood analytical method in which surfactant added to the blood test sample is at least one selected from surfactants that do not destroy blood platelet, a dry analytical element and an analytical kit utilizing the method. Excerpt(s): This invention relates to a method for analyzing a blood test sample containing blood platelet collected from a human body, a dry analytical element and an analytical kit utilizing the method. An analytical method, in which blood collected from a human body is analyzed as a test sample to diagnose human diseases, has conventionally been performed. The method is generally classified into two types, that is, a wet analytical method in which a reagent(s) necessary for designed analysis and a test sample are added into water to prepare a solution to allow some detectable reaction to take place; and a dry analytical method in which a test sample is supplied onto a layer (gelatin layer, for example) containing reagents previously in dry state to allow some detectable reaction to take place in the layer. In the case where enzyme activity is measured by utilizing a dry analytical method, for example, such an analytical element is utilized that has one or more layers containing reagents in dry state on an undercoated transparent polyethylene terephthalate (PET) base and a spreading layer of tricot knitted cloth made of polyester spun yarn laminated on the layer.

Rapid multiple panel of biomarkers in laboratory blood tests for TIA/stroke Inventor(s): Dambinova, Svetlana A.; (Atlanta, GA) Correspondence: King & Spalding; 191 Peachtree Street, N.E.; Atlanta; GA; 30303-1763; US Patent Application Number: 20030096331 Date filed: August 2, 2001 Abstract: A methods, kits and compositions for diagnosing a central nervous system disorder, particularly transient ischemic attack or stroke, comprising measuring the level of NR2A and/or NR2B NMDA receptor or fragment thereof, in a biological sample from a human subject, and optionally measuring other biomarkers such as homocysteine and glutamate. The method is particularly useful for identifying individuals that are at risk for stroke, and for diagnosing stroke in an emergency room setting. Excerpt(s): This application claims priority under 35 U.S.C.sctn.119(e) to U.S. Provisional Application No. 60/301,297, filed Jun. 27, 2001, and under 35 U.S.C.sctn.120 to U.S. Utility application Ser. No. 09/632,749, filed Aug. 4, 2000 (currently pending), of which this application is a continuation-in-part. The present invention relates generally to the diagnosis, management and therapy of central nervous system disorders such as stroke, transient ishemic attack, and traumatic brain injury. In particular, the invention relates to methods and kits for evaluating these central nervous system disorders, in order to better respond to episodes of focal cerebral ishemia, and to best manage the risk associated with future acute incidences. Stroke or "brain attack" is clinically defined as a rapidly developing syndrome of vascular origin that manifests itself in focal loss of cerebral function. In more severe situations, the loss of cerebral function is global. A stroke occurs when the blood supply to the part of the brain is suddenly interrupted (ischemic) or when a blood vessel in the brain bursts, spilling blood into the spaces
84
Blood Tests
surrounding the brain cells (hemorrhagic). The symptoms of stroke are easy to spot: sudden numbness or weakness, especially on one side of the body; sudden confusion or trouble speaking or understanding speech; sudden trouble seeing in one or both eyes; sudden trouble walking; dizziness; or loss of balance or coordination. (National Institute of Neurological Disorders and Stroke, 2001). Stroke is the most common devastating neurologic disease in the world, and the third leading cause of death in world after heart disease and cancer. Despite recent progress understanding stroke mechanisms, stroke management is still not optimal for a number of reasons. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Real time self-adjusting calibration algorithm Inventor(s): Dangui, Nandita D.; (Los Angeles, CA), Holtzclaw, Kris R.; (Valencia, CA), Hong, Peter I.; (Santa Clarita, CA), Kanderian, Sami JR.; (Northridge, CA), Mastrototaro, John J.; (Los Angeles, CA), Shin, John J.; (Glendale, CA) Correspondence: Medtronic Minimed, INC.; 18000 Devonshire Street; Northridge; CA; 91325-1219; US Patent Application Number: 20020161288 Date filed: May 8, 2002 Abstract: A method of calibrating glucose monitor data includes collecting the glucose monitor data over a period of time at predetermined intervals. It also includes obtaining at least two reference glucose values from a reference source that temporally correspond with the glucose monitor data obtained at the predetermined intervals. Also included is calculating the calibration characteristics using the reference glucose values and the corresponding glucose monitor data to regress the obtained glucose monitor data. And calibrating the obtained glucose monitor data using the calibration characteristics is included. In preferred embodiments, the reference source is a blood glucose meter, and the at least two reference glucose values are obtained from blood tests. In additional embodiments, the calculation of the calibration characteristics is obtained using linear regression and in particular embodiments, least squares linear regression. Alternatively, the calculation of the calibration characteristics is obtained using non-linear regression. Excerpt(s): This application is a continuation-in-part of U.S. patent application Ser. No. 09/511,580, filed Feb. 23, 2000 and entitled "Glucose Monitor Calibration Methods", which is herein incorporated by reference in its entirety. This invention relates to glucose monitor systems and, in particular embodiments, to calibration methods for glucose monitoring systems. Over the years, body characteristics have been determined by obtaining a sample of bodily fluid. For example, diabetics often test for blood glucose levels. Traditional blood glucose determinations have utilized a painful finger prick using a lancet to withdraw a small blood sample. This results in discomfort from the lancet as it contacts nerves in the subcutaneous tissue. The pain of lancing and the cumulative discomfort from multiple needle pricks is a strong reason why patients fail to comply with a medical testing regimen used to determine a change in a body characteristic over a period of time. Although non-invasive systems have been proposed, or are in development, none to date have been commercialized that are effective and provide accurate results. In addition, all of these systems are designed to provide data at discrete points and do not provide continuous data to show the variations in the characteristic between testing times.

AIDS in the Workplace Source: AIDS and the Law; A Guide for the Public. Contact: Yale University Press, PO Box 209040, New Haven, CT, 06520-9040, (203) 4320940. Summary: This chapter provides a summary of legal principles potentially applicable to Acquired immunodeficiency syndrome (AIDS) in the workplace and their implications for employees and employers. Traditionally, employers had complete discretion to refuse to employ people under the "Employment at Will Rule." A relatively new body of law aimed at preventing discrimination against the disabled partially limits this

89
discretion. If AIDS and AIDS-related complex (ARC) are defined as handicaps, as seems likely, Federal, State, and local laws are in effect that limit employer discretion in hiring, firing, and setting conditions of employment. Several States and cities also have passed laws directly prohibiting either AIDS-related discrimination or the use of blood tests to screen employees for AIDS. Other laws governing unemployment, health, and pension benefits also limit discretion, and there are labor laws governing the treatment of employees afraid to work due to fear of AIDS. It is concluded that for reasons of law, public policy, compassion, and common sense, employers should educate themselves and their employees to avoid AIDS-related discrimination. •

A moderator asks an obstetrician-gynecologist and a dietitian about various aspects of gestational diabetes. Topics include what gestational diabetes is and what causes it, how it differs from other kinds of diabetes, and how it will affect a baby. Gestational diabetes, which usually develops between 24 to 26 weeks of gestation, is caused when the placenta produces chemicals that interfere with insulin and the
Multimedia 97
mother's body cannot compensate for this change. Risk factors for gestational diabetes include being over 30 years old and overweight, having a family history of diabetes, and having had a baby over 9.5 pounds or a stillborn infant. Most women have no symptoms so blood tests are usually performed between 24 and 28 weeks of gestation. Many women who have gestational diabetes can manage the disease with diet and exercise. However, some women may need insulin to manage their diabetes. If a woman needs insulin, she needs to self monitor her blood glucose levels, give herself insulin injections, have her pregnancy monitored more closely, do urine tests to monitor ketones, and have tests to make sure the baby is developing properly. Participants also answer questions about the effect of gestational diabetes on the baby, the impact of gestational diabetes on delivery, and other pregnancy complications. The videotape concludes by identifying sources of additional information. •

Keynote Speaker: 3rd National Forum on AIDS and Hepatitis B, Washington, D.C., November 21-23, 1988 Contact: Sound Solution, PO Box 566074, Dallas, TX, 75356, (214) 258-6144. Summary: In this sound recording, Dr. Ralph Reed, Deputy Assistant Secretary of the U.S. Department of Health and Human Services, delivers the keynote address at the Third National Forum on AIDS and Hepatitis B, presented by the National Foundation for Infectious Diseases, Nov. 23, 1988. He compliments the group on the topic of the conference: Protecting America's health-care system. He says that sometimes it seems that the Public Health Service worries more about the health of doctors and nurses than they do themselves. However, the epidemic of Acquired immunodeficiency syndrome (AIDS), caused by the Human immunodeficiency virus (HIV), is changing many physicians' attitudes. He says that people who were nonchalant about the dangers of Hepatitis B are becoming more cautious about AIDS, although only 12 health-care workers worldwide have ever died of AIDS; while 10,000 to 12,000 health care workers

each year are infected by Hepatitis B in the United States. Of these, 200 to 300 die. He then describes the program begun by the Indian Health Service to combat Hepatitis B in Alaska. A screening program of blood tests in the Native Alaskan villages identified the geographic hot spots where Hepatitis B was most prevalent. People in these villages were immunized first; then the remainder of the population of 75,000 Native Alaskans, including all newborn babies. Fifteen hundred chronic carriers were identified, and these are now being checked twice a year in their villages. He says that without this program, 40 per cent of male chronic carriers and 20 per cent of female chronic carriers would die of liver cancer. He adds that this is the first Hepatitis B program in the world to screen pregnant females and immunize newborn babies. Dr. Reed says that the success of the program is due to the availability of several good vaccines. This, unfortunately, is not the case with AIDS. There is no vaccine and no cure. The only thing that the PHS can do is to tell people how to avoid AIDS, and a booklet about AIDS was mailed to every family in the United States, 107 million booklets in all. Also, he says, 13 regional centers for AIDS education and training have been set up across the country. These centers provide consultation and training for the primary-care providers who will deal dire.

Liver Tests: Simple Blood Tests Can Reveal a Lot Source: Mayo Clinic Health Letter. 18(5): 1-3. May 2000. Contact: Available from Mayo Clinic Health Letter. Subscription Services, P.O. Box 53889, Boulder, CO 80322-3889. (800) 333-9037 or (303) 604-1465. Summary: This article, from a health newsletter, reviews the liver function tests that are used to monitor liver health and disease. The author begins by reviewing the healthy functions of the liver, including regulating the composition of the blood, manufacturing vital nutrients (such as cholesterol, vitamin A, certain proteins, bile), and neutralizing toxic substances. Sometimes there is an obvious sign of a problem, such as jaundice, which is a buildup of bilirubin in the blood, resulting in a yellow appearance of the skin and eyes. The various liver tests basically screen for three types of abnormalities: liver cell damage, reduced protein levels in the blood, and failure to eliminate certain substances from the blood. Information from the blood tests, combined with a thorough physical exam and sometimes diagnostic imaging, may be enough to reach a specific diagnosis; sometimes a liver biopsy is added to the list of diagnostic tests. Some of the more common liver disorders that are detected with these tests are viral hepatitis, alcohol or drug related liver disease, liver cancer, nonalcoholic steatohepatitis (a form of fatty liver), and hemochromatosis (high amounts of iron stored in the body). One sidebar reviews the drugs that can lead to liver toxicity. The author concludes that mild liver test abnormalities are normal; however, significantly abnormal test results should never be ignored. 1 figure.

What Blood Tests Tell Us Source: Harvard Women's Health Watch. 7(3): 6. November 1999. Contact: Available from Harvard Women's Health Watch. P.O. Box 420068, Palm Coast, FL 32142-0068. (800) 829-5921 or (904) 445-4662. Summary: This brief newsletter article describes the standard blood tests that may be done to diagnose disease or monitor risk factors. The author uses the metaphor of the bloodstream as a river that brings oxygen and other vital nutrients to the body's cells and carries waste away from them. This 'river' also transports the cellular and molecular forces that fight disease, and ferries hormones from the glands to the tissues. By sampling this stream, doctors can identify elevated risk in people who are healthy and pick up clues to the sources of symptoms in those who are sick. The few cubic centimeters of blood contain millions of cells and molecules, each of which can vary in number according to the person's state of health. The lab report resulting from a blood test usually consists of two sections: hematology, which provides information about blood cells, and chemistry, which furnishes data about plasma. The bulk of the article consists of a chart that explains the results of a typical blood test. The chart lists the lab values typically studied, the range of results considered normal, and the significance of values outside the normal range. Lab values included are WBC (white blood cells), HCT (hematocrit), PLT (platelets), CHOL (total cholesterol), HDL ('good' cholesterol), LDL

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for blood tests. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with blood tests. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Diagnosis and Treatment of Chronic Intestinal Pseudo-Obstruction in Children: Report of Consensus Workshop Source: Atlanta, GA: Children's Motility Disorder Foundation. 1997. 37 p. Contact: Available from Children's Motility Disorder Foundation. 225 Peachtree Street, NE, Suite 1430, Atlanta, GA 30303. (800) 809-9492 or (404) 529-9200. Fax (404) 529-9202. E-mail:
[email protected]. PRICE: Single copy free. Summary: The diagnostic term 'chronic intestinal pseudo-obstruction' (CIP) is often used without real regard of its meaning. The resultant inconsistency in the use of the term has hampered the clinical investigation and management of children with disorders of gastrointestinal motility. To address these problems, a Consensus Working Group was convened to arrive at a clear definition of CIP and to suggest an approach for the diagnosis and treatment of CIP; this document is the report of that Working Group. The term pseudo-obstruction denotes signs and symptoms resembling a physical obstruction to luminal flow, but without a true mechanical obstruction. CIP is a rare, severe, disabling disorder characterized by repetitive episodes or continuous symptoms and signs of bowel obstruction, including radiographic documentation of dilated bowel with air-fluid levels, in the absence of a fixed, lumen-occluding lesion. Disorders associated with primary CIP are classified as either myopathy or neuropathy depending on histopathology. Disorders causing secondary CIP are classified according to the presumed underlying pathophysiology, which facilitates an organized approach to evaluation. The document describes diagnostic approaches, including motility testing, screening blood tests, measurement of transit, antroduodenal manometry, electrogastrography, and histology. The document concludes with a brief description of treatment options, including optimal nutrition, treatment of bacterial overgrowth, cisapride, bowel decompression, and small intestine transplant. 2 figures. 2 tables. 174 references.

[email protected]. Website: www.eparent.com. PRICE: $5.95. Summary: This brief article on the role of diet is from a monograph written to soften the blow of receiving the diagnosis of kidney failure by providing patients, caregivers, and their families some practical, easy to read information. The articles are written to be practical enough for patients to use, yet informative enough that professionals can refer to them as well. This article recommends that any individual with kidney disease (either chronic kidney failure or end stage renal disease, ESRD) be referred to a renal dietitian for nutrition consultation. The renal dietitian will perform a complete nutrition assessment that includes a review of the individual's medical, surgical, and diet histories, blood tests, and medications. After the information is collected and reviewed, the dietitian develops a nutritional care plan with objectives and goals. The care plan includes nutrient requirements, such as the amount of protein and calories that the person needs to maintain a good nutritional status. The author notes that the ability to incorporate cultural foods, practices, and preferences in the dietary plan is important for dietary compliance. Whatever the belief and practice, every diet plan needs to be individualized for the person who must follow it. The article includes the toll free number of the National Kidney Foundation (800 622 9010) through which readers can locate a renal dietitian. •

Client Satisfaction With Inpatient and Outpatient HIV/AIDS Services in New South Wales Contact: New South Wales Department of Health, AIDS Bureau, 150 Albion St, Surry Hills. Summary: This report of a survey of client satisfaction with inpatient and outpatient HIV/AIDS services in New South Wales (NSW) presents findings from six outpatient and six inpatient clinics. The total number of respondents were 272 patients in an outpatient clinic and 72 patients in an inpatient facility. Both the outpatient and inpatient questionnaires contained 24 assessment questions. Results indicate that the outpatient respondents registered much more satisfaction with services than dissatisfaction, yet there was considerable variation of item scores within, and between, clinics. The inpatient respondents were more satisfied than dissatisfied; however, there was much variation within and among inpatient services. The results suggest that inpatients and outpatients want more information and explanations. Outpatients also want reduced waiting times for seeing the doctor, getting blood tests done, and getting prescriptions.

AIDS - Related Knowledge, Attitudes, and Behavior of Virginia College Students: The Virginia Statewide AIDS Needs Assessment Contact: Virginia Commonwealth University, Center for Public Policy, Survey Research Lab, PO Box 843065, Richmond, VA, 23284-3065, (804) 828-8813, http://www.vcu.edu/srl. Summary: This report presents the findings of a survey of Virginia college and university students regarding their Knowledge, Attitudes, and Behaviors (KAB) related to Acquired immunodeficiency syndrome (AIDS), caused by Human immunodeficiency virus (HIV). Although public awareness of AIDS among this population was high, there were substantial gaps in knowledge, probably reflecting media emphases and discussions of the disease. The report concludes that there is a need for improved information dissemination about AIDS on college campuses. Virginia undergraduates strongly support compulsory blood tests for health professionals but only a minority believe that employers have a right to test their employees. Other situations produce moderate levels of support for testing. A small minority of respondents have extremely negative attitudes toward Persons with AIDS (PWA's), supporting quarantines and expulsion of children with AIDS from schools. Larger proportions agree they would not like to live near, work with, or go to school with PWA's. The students feel that AIDS and drug abuse pose very serious national problems and, while they agree that the government should set up AIDS clinics, they are more ambiguous about governmental responsibility to pay for treatment costs. There is some evidence that public awareness about AIDS has modified the respondents' sexual behavior, causing them to adopt some aspects of safer sexual conduct, although only 25 percent reported using a condom during each sexual encounter. Nearly all respondents would take the HIV-antibody test if a sex partner were found to be HIV positive.

Special Report: Arthritis Source: Boston, MA: Harvard Medical School. 1999. 46 p. Contact: Available from Harvard Medical School. Health Publications Group, Department SR, P.O. Box 380, Boston, MA 02117-0380. PRICE: $16.00 plus shipping and handling. Summary: This report provides people who have arthritis with information on the features, diagnosis, and treatment of osteoarthritis (OA), rheumatoid arthritis (RA), and ankylosing spondylitis (AS). The report begins by explaining the difference between arthritis and rheumatism. This is followed by an overview of the joints and the immune system in rheumatic diseases. Topics include types of joints, joint design, the functioning of the immune system, the occurrence of inflammation in arthritis, and the role of genetics. The report then discusses OA, RA, and AS in terms of their evolution, symptoms, possible causes, diagnosis, and treatment. Other seronegative spondyloarthropathies, including Reiter's syndrome, psoriatic arthritis, and enteropathic arthritis, are described. A section of the report is devoted to the diagnosis of rheumatic diseases, focusing on obtaining a medical history; assessing pain and stiffness; conducting a physical examination by observing how the patient moves, examining the joints for abnormalities, and moving the joints through their range of motion to detect pain, resistance, unusual sounds, and instability; and performing studies such as blood tests, radiography, other imaging techniques, and arthrocentesis. Another section focuses on using physical therapy to treat people who have arthritis. Modalities discussed are heat and cold therapy, exercise, diathermy, and transcutaneous electrical nerve stimulation. In addition, the report provides suggestions on living with arthritis.

Human Immunodeficiency Virus (HIV) Infection Contact: American Academy of Physician Assistants, 950 N Washington St, Alexandria, VA, 22314, (703) 836-2272, http://www.aapa.org/. Summary: This statement presents the policies of the American Academy of Physician Assistants regarding Acquired immunodeficiency syndrome (AIDS) and Human immunodeficiency virus (HIV). Following an introductory section which outlines the risk factors involved in HIV transmission, the epidemiology of AIDS, and the symptoms of the disease, the statement declares that the code of ethics of this profession demands health-service accessibility to all persons, including those with AIDS or HIV infection. Physician assistants are urged to participate in education and HIV-specific training programs in order to maintain updated information about HIV infection including diagnosis, management, treatment, and counseling of HIV-positive persons. The Academy calls on Federal, State, and local governments to enact or strengthen laws prohibiting discrimination against HIV-positive persons in the areas of employment, housing, education, insurance, health service accessibility, and other civil rights. The policy statement maintains that, while the HIV-antibody test is appropriate when needed for early diagnosis, compulsory blood tests for entire populations are unjustifiable ethically or practically. Furthermore, the Academy does not recommend routine testing of hospitalized or pre-operative patients without their informed consent. Finally, the statement supports anonymous reporting and anonymous population-based studies and suggests that HIV-positive persons should be encouraged to notify their sexual or needle-sharing partners of their infection. Legislation should prohibit any disclosure of identifying information pertaining to an individual's HIV status without express consent, except when clearly required for medical or legal reasons.

Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.

The HSTAT URL is http://hstat.nlm.nih.gov/.
17
Other important documents in HSTAT include: the National Institutes of Health (NIH) Consensus Conference Reports and Technology Assessment Reports; the HIV/AIDS Treatment Information Service (ATIS) resource documents; the Substance Abuse and Mental Health Services Administration's Center for Substance Abuse Treatment (SAMHSA/CSAT) Treatment Improvement Protocols (TIP) and Center for Substance Abuse Prevention (SAMHSA/CSAP) Prevention Enhancement Protocols System (PEPS); the Public Health Service (PHS) Preventive Services Task Force's Guide to Clinical Preventive Services; the independent, nonfederal Task Force on Community Services’ Guide to Community Preventive Services; and the Health Technology Advisory Committee (HTAC) of the Minnesota Health Care Commission (MHCC) health technology evaluations. 18 Adapted from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html. 19
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on blood tests can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to blood tests. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to blood tests. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “blood tests”:

The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on blood tests. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits.

Common Blood Tests: What They Mean, What You Can Do Contact: Project Inform, HIV Treatment Hotline, 205 13th St Ste 2001, San Francisco, CA, 94103, (415) 558-8669, http://www.projectinform.org. Summary: This brochure provides basic information about interpreting laboratory blood tests used to monitor the progress of Human immunodeficiency virus (HIV) infection and to implement drug therapy, if appropriate. It particularly focuses on the T4 - helper cell tests but also covers the P24 - antibody test, the P24 - antigen test, the Beta22 microglobulin test, and the complete blood count. Results of the T4 - helper test are categorized into three ranges, depicting the severity of immediate danger of contracting an AIDS - related infection or initiation of antiviral treatment. It notes that wide variations in results can be minimized by observing long - range trends, testing at the same time each day, using the same laboratory for testing, and not testing when sick or during periods of stress, drug use, or lack of sleep. It also notes that to date, physicians do not agree on when to start drug therapy. Some prefer to wait until the patient becomes ill to initiate drug treatment, even through the virus has been identified.

Source: National Institute of Diabetes and Digestive and Kidney Diseases, National Institutes of Health http://www.healthfinder.gov/scripts/recordpass.asp?RecordType=0&RecordID=6520 The NIH Search Utility
The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to blood tests. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments
