HbA1c, or hemoglobin A1c, is a blood test that measures your average blood sugar (glucose) levels over the past 2 to 3 months. It is commonly used to diagnose and monitor diabetes and prediabetes. Here’s what the HbA1c levels indicate:

HbA1c Level (%) Diagnosis

Below 5.7 Normal
5.7 to 6.4 Prediabetes
6.5 or above Diabetes

  • Normal: Below 5.7% indicates healthy blood sugar control.
  • Prediabetes: 5.7% to 6.4% suggests an increased risk of developing diabetes.
  • Diabetes: 6.5% or higher typically indicates diabetes.

HbA1c is a valuable tool for managing diabetes, as it provides a long-term view of blood sugar levels, unlike daily glucose tests which only show a snapshot.
