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
- Monitor blood sugar control in people with diabetes
How Does It Work?
- 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.
- Since red blood cells regenerate every 3 months, the test reflects your average blood sugar levels over that period.
A1C Ranges:
A1C Level Diagnosis
Below 5.7% Normal
5.7%–6.4% Prediabetes
6.5% or higher Diabetes
For most people with diabetes, the goal is to maintain an A1C level of less than 7%, but this may vary based on individual health conditions.
