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 primarily used for:
- Diagnosing prediabetes and diabetes:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
- Monitoring diabetes management: It helps assess how well your blood sugar is controlled over time.
- Estimating average glucose levels: The test provides an estimated average glucose (eAG) value, which correlates with your A1C percentage.
This test is particularly useful because it reflects long-term glucose levels rather than a single moment, offering a more comprehensive view of blood sugar control.
