a test that evaluates the body's response to glucose after a period of fasting; used to check for diabetes mellitus
Test that measures blood sugar levels over a certain amount Test of time in a patient after he drinks a beverage that contains a measured amount of sugar
A test to determine if a person has diabetes. The test is done in a lab or doctor's office in the morning before the person has eaten. A period of at least 8 hours without any food is recommended prior to doing the test. First, a sample of blood is taken. Then the person drinks a liquid that has glucose (sugar) in it. Two hours later, a second blood test is done. If the results of the fasting or first blood test are abnormal yet still not high enough to be considered in the diabetes range, then the person is said to have glucose intolerance. A fasting blood sugar greater than 126 mg/dl is considered diabetes. If the 2 hour blood test is abnormal but still not high enough to be considered in the diabetic range, this too, is considered an abnormal glucose tolerance. If the two hour test result shows a blood sugar greater than 200 mg/dl, the person is consider to have diabetes.
A screening done between 24-28 weeks of pregnancy to check for gestational diabetes
test of the body's ability to metabolize carbohydrates; used in the diagnosis of hypoglycemia and diabetes mellitus
A test that measures carbohydrate (glucose) tolerance (the ability to utilize serum glucose appropriately). In the GTT, the patient's ability to tolerate a standard oral glucose load is evaluated by assessing serum and urine specimens for glucose levels. Blood samples are taken before the glucose is ingested, glucose is given by mouth, and blood (and often, urine) glucose levels are repeated 30 min., 1 hour, 2 hours , and 3 hours after ingestion.
A test given to measure a person's glucose and/or insulin levels over a given period of time. The test begins in a lab or doctor's office in the morning before the person has eaten (fasting). A first sample of blood is taken from the person. Then the person drinks a liquid that has glucose (sugar) in it called glucola. After one hour, a second blood sample is drawn, and, after another hour, a third sample is taken. GTT's can be extended for longer periods of time if ordered by a physician. The object is to see how the person's glucose and/or insulin levels are affected by the ingested glucola over time.
test: Test for detecting diabetes.
A blood test used to make the diagnosis of diabetes, including gestational diabetes. The test is given in a lab or doctor's office in the morning before the person has eaten. A first sample of blood is taken from the person. Then the person drinks a liquid containing 100 grams of glucose (sugar) in it. After one hour, a second blood sample is drawn, and, after another hour, a third sample is taken. The object is to see how well the body deals with the glucose in the blood over time.
A screening test for insulin resistance, diabetes, and gestational diabetes. Usually blood is drawn at fasting, and then the patient drinks or eats a certain amount of glucose. Blood is drawn at one hour, two hours and three hours to check glucose levels. Some may have an additional blood draw at a half hour.
This test is performed in a doctor's office or lab to diagnose diabetes. After an overnight fast, patients drink a very concentrated sugar solution and have their blood sugar levels measured hourly for three hours. Women who may be at risk for developing diabetes during their pregnancy may take this test.
a diagnostic test for diabetes involving a drink of glucose (after an overnight fast) followed by a series of blood glucose estimations over 2 hours
A test which measures the body's ability to metabolize carbohydrates. The patient is administered a standard dose of glucose. Blood and urine and collected and tested periodically to determine the effectiveness of the metabolism.
A test commonly done in physicians' offices as a part of a complete examination or specifically be cause diabetes is suspected. The test enables your physician to chart your blood's glucose level over a several hour period. It involves taking a small specimen of blood from your arm. You usually drink a beverage containing glucose at the start of the testing period.
a test to determine if a person has diabetes. The test is done in a lab or doctor's office in the morning before the person has eaten. First a sample of blood is taken. Then the person drinks a liquid that has glucose (sugar) in it. Periodically, another sample of blood is taken to see how the body processes the glucose in the blood.
A blood test done to make the diagnosis of diabetes mellitus . The test may also be done for other purposes such as to diagnose hypoglycemia (low blood sugar) or a malabsorption syndrome in which sugar is not absorbed properly through the intestines into the bloodstream. See the entire definition of Glucose tolerance test
A blood test used to make the diagnosis of diabetes, including gestational diabetes. After drinking a liquid containing 100 grams of glucose, blood is drawn every hour for 3 hours. Two or more abnormally elevated blood sugar levels indicate gestational diabetes.
This is the next step if a glucose screening test comes back elevated. A fast is required prior to this three-hour study, which consists of consuming a highly concentrated sweet glucose drink before having blood drawn at specific intervals. If the blood work of a pregnant woman comes back again with elevated numbers, there's a high probability that she has gestational diabetes.
see oral glucose tolerance test.
A glucose tolerance test in medical practice is the administration of glucose to determine how quickly it is cleared from the blood. The test is usually used to test for diabetes, insulin resistance, and sometimes reactive hypoglycemia. The glucose is most often given orally so the common test is technically an oral glucose tolerance test (OGTT).
