Prediabetes is typically diagnosed using one of the following tests:
- A1C Test: Measures your average blood sugar levels over the past 2-3 months. Prediabetes is indicated by an A1C level between 5.7% and 6.4%.
- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. Prediabetes is indicated by a fasting glucose level between 100 mg/dL and 125 mg/dL.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and 2 hours after drinking a glucose-rich drink. Prediabetes is indicated by a 2-hour glucose level between 140 mg/dL and 199 mg/dL.
If your results fall into the prediabetes range, your doctor may recommend lifestyle changes to prevent progression to type 2 diabetes.
