Testing Blood vs Serum in DUI Cases Blood samples obtained in drunk driving cases are generally — but not always — analyzed as whole blood (sometimes called "legal blood"). Serum is the clear yellowish fluid obtained from separating whole blood into its solid and liquid components (usually by centrifuging the sample); the liquid portion of the blood is called plasma, which is similar to serum. A simple technique for visually demonstrating the concept of testing blood that has aged and been subject to possible fermentation is to bring in a fresh vial of blood and compare it to the evidentiary sample withdrawn months earlier from the defendant. www.california-drunkdriving.org /blood_vs_serum.html   (547 words)

Blood plasma - Wikipedia, the free encyclopedia Blood plasma is the liquid component of blood, in which the blood cells are suspended. Serum is the same as blood plasma except that clotting factors (such as fibrin) have been removed. It is mainly composed of water, blood proteins, and inorganic electrolytes. en.wikipedia.org /wiki/Blood_serum   (748 words)

MedlinePlus Medical Encyclopedia: HCG in blood serum - qualitative This is a blood test to detect beta-HCG (human chorionic gonadotropin), a hormone normally produced during pregnancy. Blood is drawn from a vein, usually on the inside of the elbow or the back of the hand. The serum HCG level may also be high in women with certain types of ovarian tumors or men with testicular tumors. www.nlm.nih.gov /medlineplus/ency/article/003509.htm   (544 words)

Blood Serum Ions Plasma is prepared by withdrawing a blood sample and placing it in a test tube containing a chemical that prevents blood from clotting (an anti-coagulant). Serum is prepared by withdrawing a blood sample, placing it in a test tube, and allowing it to clot. Serum chloride levels sometimes increase to abnormal levels as an undesirable side effect of medical treatment with sodium chloride or ammonium chloride. www.life-enthusiast.com /twilight/research_blood_serum.htm   (1982 words)

► Serum globulin electrophoresis Serum globulin electrophoresis is a form of protein electrophoresis that, in particular, examines the globulin proteins (see protein electrophoresis - serum; immunoelectrophoresis - serum). Serum proteins are grossly separated into albumin and globulins, that is, total protein = albumin + globulin. Albumin is the protein of highest concentration in the serum (plasma, the fluid portion of blood, is serum plus clotting proteins). www.umm.edu /ency/article/003544.htm   (647 words)

► Protein electrophoresis - serum Protein electrophoresis - serum is a test that roughly quantitates the various protein fractions in serum (see also immunoelectrophoresis - serum; immunofixation - serum; serum globulin electrophoresis). Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. www.umm.edu /ency/article/003540.htm   (734 words)

Blood alcohol test   (Site not responding.

I think that virtually everyone measures serum alcohol levels and that that was probably what the law intended to specify, using a less precise, non-scientific term. The practical difference in court would be approximately 0.01% which may keep someone with a "blood" (serum) alcohol level of.10 -.11% from conviction as this would precisely reflect a whole blood alcohol of approximately 0.09%, a result less than the legal limit. www.palpath.com /alcohol.htm   (281 words)

Total Serum Protein A total serum protein test measures the total amount of protein in blood serum as well as the amounts of albumin and globulin. An increase in serum globulin can indicate a rare type of blood cancer called multiple myeloma, leukemia, an autoimmune disease (such as rheumatoid arthritis, systemic lupus erythematosus, or autoimmune hepatitis), kidney disease, liver disease, a chronic infection (such as tuberculosis), hemolytic anemia, sarcoidosis, or severe dehydration. If the results of the total serum protein test are abnormal (especially the globulin levels), another test called serum protein electrophoresis is often done. www.webmd.com /hw/health_guide_atoz/hw43614.asp   (1189 words)

Soluble IL-2 receptor levels in serum from blood donors seropositive for HIV. Soluble IL-2 receptor levels in serum from blood donors seropositive for HIV.

Using a combination of powerful mass spectrometry technologies with improvements in sample preparation, we have performed a proteomic analysis with sub-mL quantities of serum, and increased the measurable concentration range for proteins in blood serum beyond previous reports. With this study, we have performed the most extensive analysis of serum proteins to date and laid the foundation for future refinements in the identification of novel protein biomarkers of disease. www.osti.gov /energycitations/product.biblio.jsp?osti_id=15004728   (350 words)

The test, which detects the amounts of two proteins in a woman’s blood serum, accurately identified more cases of cancer than did tests for either of the two proteins alone.

Understanding Osteoporosis, Calcium, and Estrogen Activity As long as there is adequate calcium in the blood stream from dietary sources, bone calcium can remain fairly consistent with calcium being reabsorbed from the bone and deposited at similar rates. However when blood serum calcium levels are constantly low, the body reabsorbs calcium into the blood from the bone faster than it can be deposited back, resulting in a loss of bone mass. The blood, the heart, the muscular system, the nervous system, the hormonal system, as well as the kidneys, and the gastrointestinal system are all affected by calcium and demand a specific calcium balance. www.healingwithnutrition.com /odisease/osteoporosis/calcium_estrogen.html   (2552 words)
