Have a fasting blood
sugar level that is equal to or greater than 126 mg/dL. A fasting blood sugar
test (fasting plasma glucose) is done after not eating or drinking anything but
water for 8 hours.
Have a 2-hour oral glucose tolerance test (OGTT) result that is equal to or greater than 200 mg/dL. An OGTT is most commonly done to check for diabetes that occurs with pregnancy (gestational diabetes).
If the results of your
fasting blood sugar test are between 100 mg/dL and 125 mg/dL, your OGTT result is between 140 to 199 mg/dL (2 hours after the beginning of the test), or your hemoglobin A1c is 5.7% to 6.4%, you have
prediabetes. This means that your blood sugar is above normal but not high enough to be diabetes. Discuss with your doctor how
often you need to be tested.1
