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

• 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 glucose-rich drink.

  • Normal: Less than 140 mg/dL
  • Prediabetes: 140 to 199 mg/dL
  • Diabetes: 200 mg/dL or higher

If you suspect diabetes, consult your healthcare provider for appropriate testing and interpretation of results.
