Generally, two kinds of blood tests are performed to measure the amount of sugar in the blood. A fasting plasma glucose (FPG) test may be done, in which the blood is tested after the patient hasn't eaten for eight hours beforehand. Normally, your blood glucose level (BGL) will measure less than 100 mg/dL; in a diabetic patient, this test would yield a result of over 126 mg/dL. Prediabetes is diagnosed when this measurement falls between 100 and 125 mg/dL. An oral glucose tolerance test (OGTT) may be ordered instead of an FPG test to diagnose prediabetes, as it is more sensitive. In this procedure, an FPG will be performed first; then, a second test will be conducted two hours after ingesting a sugary drink. The two tests allow for comparison and show how well the body digests the sugar. The second test should result in a measurement of 140 mg/dL or less; a diabetic patient would see a reading of 200 mg/dL or more. Prediabetes is diagnosed when the result falls between 140 and 199 mg/dL.
