The A1C test measures your average blood sugar levels over the past 2-3 months. The results are reported as a percentage, and the ranges are as follows:

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

These ranges help diagnose prediabetes and diabetes and monitor how well your blood sugar is being managed over time.
