how to determine if you are prediabetic
Testing should be carried out in a health care setting (such as your doctorâs office or a lab). If your doctor determines that your blood glucose level is very high, or if you have classic symptoms of high blood glucose in addition to one positive test, your doctor may not require a second test to diagnose diabetes.f you have prediabetes, you should be checked for type 2 diabetes every one to two years. Results indicating prediabetes are: 1  An A1C of 5.7% â 6.4%. 2  Fasting blood glucose of 100 â 125 mg/dl. 3  An OGTT 2 hour blood glucose of 140 mg/dl â 199 mg/dl.
