what does a1c mean diabetes

The A1C test, also known as the hemoglobin A1C or HbA1c test, is a blood test that measures your average blood sugar levels over the past 2-3 months. It is commonly used to diagnose and monitor diabetes and prediabetes.

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

The A1C test works by measuring the percentage of your red blood cells that have sugar-coated hemoglobin. Since red blood cells regenerate every 3 months, this test provides a long-term view of your blood sugar control.

For people with diabetes, the A1C test helps assess how well their condition is managed. The goal for most adults with diabetes is to keep their A1C level below 7% to reduce the risk of complications.
