Hgt Test Glucose. A blood glucose test is a blood test that screens for diabetes by measuring the level of glucose (sugar) in a person’s blood. To test for glucose with a typical glucose meter, place a small sample of blood on a disposable test strip and place the strip in the meter.

This test is called an oral glucose tolerance test (ogtt). The glucose tolerance test is a medical test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood. The whole blood serum values are expected but the csf values is elevated.
