Encyclopedia article: Glucose tolerance test   (Site not responding. Last check: 2007-10-09) A Glucose Tolerance Test in medical practice is the administration of glucose (A monosaccharide sugar that has several forms; an important source of physiological energy) to determine how quickly it is cleared from the blood. The test is usually used to test for diabetes (Any of several metabolic disorders marked by excessive urination and persistent thirst), insulin resistance (additional info and facts about insulin resistance), and sometimes reactive hypoglycemia (additional info and facts about reactive hypoglycemia). Using a glucose tolerance in this context resembles use of a Rorschach test in that it is often used to support a diagnosis that the patient and doctor are already reaching agreement on based on other evidence, but it is inadequate by itself to confirm or refute the diagnosis (unlike its use for diabetes). www.absoluteastronomy.com /encyclopedia/g/gl/glucose_tolerance_test.htm   (500 words)

► Glucose tolerance test Glucose is the sugar that the body uses for energy. Patients are given a known amount of glucose by vein for three minutes, and blood insulin levels are measured before glucose and at one and three minutes. The oral glucose tolerance test is indicated to screen pregnant women for gestational diabetes mellitus between 24 and 28 weeks of pregnancy. www.umm.edu /ency/article/003466.htm   (485 words)

Blood Glucose - [Medical Test] Glucose is a type of sugar found in carbohydrate foods. Rarely, an oral glucose tolerance test may be done with a blood glucose test to confirm a diagnosis of diabetes. A blood glucose test uses a blood sample taken from a vein or a small blood sample taken from pricking your finger. www.bchealthguide.org /kbase/topic/medtest/hw8252/descrip.htm   (374 words)

Glucose Tests: The Test Blood glucose testing can be used to screen healthy, asymptomatic individuals for diabetes and pre-diabetes because diabetes is a common disease that begins with few symptoms. Increased urine glucose levels may be seen with medications, such as estrogens and chloral hydrate, and with some forms of renal disease. Hypoglycemia is characterized by a drop in blood glucose to a level where first it causes nervous system symptoms (sweating, palpitations, hunger, trembling, and anxiety), then begins to affect the brain (causing confusion, hallucinations, blurred vision, and sometimes even coma and death). www.labtestsonline.org /understanding/analytes/glucose/test.html   (1305 words)
