The HbA1c blood test, also known as the hemoglobin A1c test, 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.

How It Works:

  • Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
  • The test measures the percentage of hemoglobin that is coated with sugar (glycated hemoglobin).
  • Since red blood cells regenerate every 3 months, the test reflects your long-term blood sugar control.

Key Ranges:

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

Why It’s Important:

  • It helps diagnose diabetes and prediabetes.
  • It monitors how well your diabetes treatment plan is working.
  • It provides a more comprehensive picture than daily blood sugar checks.

Preparation:

  • No fasting is required for the HbA1c test.
  • It can be done at a doctor’s office or lab with a simple blood draw.
