The primary blood tests used to diagnose and monitor diabetes include:

  • A1C Test: Measures your average blood sugar levels over the past 2-3 months. It is used to diagnose prediabetes and diabetes, and to monitor how well your diabetes is being managed.

    • 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 to 125 mg/dL
    • Diabetes: 126 mg/dL or higher
  • Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary drink. It is often used to diagnose gestational diabetes.

  • Random Blood Sugar Test: Measures blood sugar at any time of the day, regardless of when you last ate.

These tests help healthcare providers determine if you have diabetes or prediabetes and how well your treatment plan is working.
