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 to 3 months. It is commonly used to diagnose prediabetes and diabetes, as well as to monitor how well you are managing your condition if you have diabetes.
- How it works: The test measures the percentage of your red blood cells that have sugar-coated hemoglobin. Since red blood cells regenerate every 3 months, the A1C test reflects your average blood sugar levels over that period.
- Normal range: Below 5.7%
- Prediabetes range: 5.7% to 6.4%
- Diabetes range: 6.5% or above
For people with diabetes, the A1C goal is typically 7% or less, but this may vary based on individual health conditions.
