what does a1c mean in medical terms

In medical terms, A1C (also known as HbA1c or glycated hemoglobin) is a blood test that measures your average blood sugar 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 A1C test measures the percentage of hemoglobin that is coated with sugar. Since red blood cells regenerate every 3 months, this test provides a long-term view of blood sugar control.

• Normal Range:

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

• Purpose: The A1C test helps healthcare providers assess how well diabetes is being managed and whether treatment plans need adjustment.
