Diagnosing Diabetes

Doctors use several tests to check for diabetes and prediabetes in their patients. All of them require that blood be drawn and tested in a medical lab. The first one is called the fasting plasma glucose (FPG) test. This test measures a person's blood glucose after eight hours of not eating or drinking anything. The FPG is most reliable when it is done in the morning, and it is also the most convenient of the three tests for diabetes or prediabetes. If the fasting glucose level is 99 mg/dL (milligrams per deciliter) or below, the person does not have diabetes. If the level is 100-125 mg/dL, the person has a kind of predia-betes called impaired fasting glucose. This person does not have type 2 diabetes yet but is likely to develop it later.

If the fasting glucose level is 126 mg/dL or higher, the doctor will perform the test again to confirm the results. If the same results appear the second day, the person has diabetes.

The oral glucose tolerance test (OGTT) is another measure of blood glucose after fasting for eight hours as well as two more hours after the person drinks a liquid containing glucose.

After eight hours of fasting, blood is drawn and its glucose level is measured to provide a baseline number. Then the per son drinks a special beverage of glucose dissolved in water. Two hours later blood is drawn again, and the glucose level is checked once more.

A blood glucose level of 140-199 mg/dL two hours after the drink means the person has a form of prediabetes called impaired glucose tolerance and is likely to develop diabetes in the future. If the level is 200 mg/dL or higher, the test will be performed again the next day. If the results are again 200 mg/dL or higher, the person has diabetes.

A glucometer measures a glucose level of 174 mg/dL (milligrams per deciliter) in a sample of blood, indicating impaired glucose tolerance.

The OGTT is also used to diagnose gestational diabetes, except that blood glucose levels are checked four times during the test. If levels are higher than normal in at least two of the four checks, the woman has gestational diabetes.

The third test is the random plasma glucose test. The blood glucose level is checked regardless of when the person last ate. This test is only for diagnosing diabetes. A person can have diabetes if the blood glucose level is 200 mg/dL or higher and also has symptoms including increased urination and thirst, weight loss for no known reason, and also is experiencing increased hunger, sores that will not heal, blurred vision, and fatigue. If this is the case, the person should undergo either the FPG or the OGTT to verify the diagnosis.
