Glucose Tolerance Test

• I/V glucose tolerance test is carried out by giving 25 g of glucose dissolved in 100 ml distilled water as intravenous injection within 5 minutes • Completion of infusion is taken as 0 time • Blood samples are taken at 10 minutes interval for the next hour • The peak value is reached within a few minutes and the value touches to near normal in 45-60 minutes 11/05/14 Biochemistry

Glucose tolerance test

The most common glucose tolerance test is the oral glucose tolerance test (OGTT) Before the test begins a sample of blood will be taken You will then be asked to drink a liquid containing a certain amount of glucose (usually 75 grams) Your blood will be taken again every 30 to 60 minutes after you drink the solution

Glucose Tests

The fasting blood glucose test (collected after an 8 to 10 hour fast) is used to screen for and diagnose diabetes A 2-hour 75 g oral glucose tolerance test (OGTT / GTT) may also be used to diagnose diabetes To be certain of a diagnosis of diabetes two tests (either the fasting glucose or the OGTT) should be done at different times

Oral Glucose Tolerance Test

Test Overview The oral glucose tolerance test (OGTT) measures the body's ability to use a type of sugar called glucose that is the body's main source of energy An OGTT can be used to diagnose prediabetes and diabetes An OGTT is most commonly done to check for diabetes that occurs with pregnancy (gestational diabetes)

Oral Glucose Tolerance Test

The 3 hour gestational glucose tolerance test requires a fasting glucose blood draw followed by a 100 gram dose of glucola then a 1 2 and 3 hour post load glucose blood draw An abnormally high fasting glucose value with a delayed return to normal indicates decreased tolerance to glucose and supports the diagnosis gestational diabetes

Screening for Gestational Diabetes

Those labelled as Average or Moderate Risk should have a formal 75-gram glucose tolerance test performed at 24-28 weeks of gestation If seen earlier a fasting blood glucose would help exclude previously existing but undiagnosed carbohydrate intolerance Subsequent management will depend on the result of the oGTT
