The HbA1c test, also known as the hemoglobin A1c test or A1c 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 diabetes over time.
How does it work?
- Glucose in your bloodstream 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 Results and What They Mean:
A1c Level (%) Diagnosis
Below 5.7 Normal
5.7 - 6.4 Prediabetes
6.5 or higher Diabetes
Why is it important?
- It provides a long-term view of blood sugar control.
- It helps healthcare providers adjust treatment plans for diabetes.
