Yes, blood tests are commonly used to diagnose diabetes. The following tests are typically used:

  • A1C Test: Measures your average blood sugar levels over the past 2-3 months. Results are given as a percentage:

    • Normal: Below 5.7%
    • Prediabetes: 5.7% to 6.4%
    • Diabetes: 6.5% or above

  • Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast.

    • Normal: Less than 100 mg/dL
    • Prediabetes: 100-125 mg/dL
    • Diabetes: 126 mg/dL or higher

  • Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a glucose-rich drink.

    • Diabetes: 200 mg/dL or higher after 2 hours

These tests help healthcare providers determine if you have diabetes or prediabetes. Always consult your doctor for accurate diagnosis and management.
