A1C Levels Chart & Ranges
Standard clinical ranges for diagnosing prediabetes and diabetes using the Hemoglobin A1C test.
Normal
Standard healthy range for adults without diabetes.
Prediabetes
Indicates a higher risk for developing Type 2 diabetes.
Diabetes
Standard threshold for a medical diagnosis of diabetes.
Understanding Your A1C Result
The A1C test measures the percentage of your hemoglobin (a protein in red blood cells that carries oxygen) that is coated with sugar (glycated). The higher your A1C level, the poorer your blood sugar control and the higher your risk of diabetes complications.
A1C Targets for People with Diabetes
Once you are diagnosed with diabetes, the goal shifts from diagnosis to management. The American Diabetes Association (ADA) generally recommends:
- Most Adults: Less than 7.0%
- Healthier Seniors: Less than 7.5%
- Children/Teens: Less than 7.0%
- Frail Seniors: Less than 8.0% or 8.5%
"Your individual A1C goal should be personalized by your doctor based on your age, other health conditions, and risk of hypoglycemia."
