Glucose Tolerance Test - More Information
The glucose tolerance test, sometimes known as the oral glucose tolerance test or OGTT, is a useful blood test in testing for diabetes risk and resistance to insulin in the body.
The glucose tolerance test starts by having the blood glucose test level drawn. Then, person will need to drink a glucose solution and, after two hours, another glucose test level is drawn to assess how quickly the body removes the glucose from the blood. In some cases, an insulin test level will also be measured during the test.
Normally, the glucose levels will return to normal when the blood is drawn after two hours. Most clinicians feel that a normal glucose tolerance test means that the person does not have diabetes. The glucose tolerance test is a slightly more intensive diabetes testing process when compared to the Diabetes Screening Panel that checks the blood glucose and hemoglobin A1c levels.
