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 your diabetes is being managed.
Key Points:
- What It Measures: The A1C test measures the percentage of your red blood cells that have sugar-coated hemoglobin.
- Normal Range: Below 5.7%
- Prediabetes Range: 5.7% to 6.4%
- Diabetes Range: 6.5% or above
Why It’s Important:
- It provides a long-term view of blood sugar control, unlike daily glucose tests which only show a snapshot.
- It helps healthcare providers adjust treatment plans for diabetes management.
