Get Tested
Tests your doctor may give you include the hemoglobin A1C test, which shows your average blood glucose levels over the past 12 weeks (5.7 to 6.4 percent is a red flag), and the fasting glucose test, which measures the glucose in your blood. Normal levels are less than 100 milligrams per deciliter (mg/dL), and the prediabetes hot zone is 100 to 125 mg/dL.
