To test for prediabetes, healthcare providers typically use one of the following tests:
- A1C Test: Measures your average blood sugar levels over the past 2-3 months. Prediabetes is diagnosed if your A1C is between 5.7% and 6.4%.
- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. Prediabetes is indicated if your fasting glucose is between 100-125 mg/dL.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and 2 hours after drinking a sugary drink. Prediabetes is diagnosed if your 2-hour glucose is between 140-199 mg/dL.
These tests help identify prediabetes, allowing for early intervention to prevent or delay the onset of type 2 diabetes.
