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 diabetes over time.
Key Points:
- Normal A1C: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
The A1C test works by measuring the percentage of your red blood cells that have sugar-coated hemoglobin. Since red blood cells regenerate every 3 months, the test provides a long-term view of your blood sugar levels.
Why is A1C Important?
- It helps in diagnosing diabetes and prediabetes.
- It provides a broader picture of blood sugar control compared to daily glucose tests.
- It is used to adjust treatment plans for people with diabetes.
