The A1C test, also known as the hemoglobin A1C or HbA1c test, 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 prediabetes and diabetes, as well as to monitor how well you are managing your condition if you already have diabetes.
- How it works: Glucose in your blood attaches to hemoglobin, a protein in red blood cells. The A1C test measures the percentage of your red blood cells that have glucose-coated hemoglobin.
- Normal range: Below 5.7%
- Prediabetes range: 5.7% to 6.4%
- Diabetes range: 6.5% or above
The A1C test is a key tool in diabetes management and prevention, but it does not replace regular blood sugar monitoring at home.
