what determines prediabetes

Prediabetes is determined by blood sugar levels that are higher than normal but not high enough to be classified as diabetes. The following tests and ranges are used to diagnose prediabetes:

• A1C Test: Measures average blood sugar levels over the past 2-3 months.

  • 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 glucose-rich drink.

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

If your results fall into the prediabetes range, it’s important to take steps to prevent or delay the onset of type 2 diabetes through lifestyle changes such as diet, exercise, and weight management.
