Quizplus · Accepted Answer

The oral glucose tolerance test (OGTT) is a test that involves drinking a concentrated glucose solution and then having blood drawn at regular intervals to measure blood glucose levels. This test is often used to diagnose diabetes or prediabetes, as it can show how well the body is able to manage glucose after a large intake of sugar. The other tests listed are used to diagnose and monitor diabetes in different ways (fasting plasma glucose measures blood glucose levels after a period of fasting, hemoglobin A1C measures average blood glucose levels over several months, and glucose meter tests are a type of at-home test that measures blood glucose levels with a handheld device).
