The Hemoglobin A1C (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 above
- Monitoring Diabetes Management: It helps assess how well your diabetes treatment plan is working.
- Estimating Average Blood Sugar: The test provides an estimated average glucose (eAG) level, which correlates with your A1C percentage.
How It Works:
- Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
- The A1C test measures the percentage of hemoglobin coated with glucose.
- Since red blood cells regenerate every 3 months, the test reflects your average blood sugar over that period.
Key Notes:
- The A1C test does not require fasting.
- It is not used to diagnose type 1 diabetes or gestational diabetes.
- Certain conditions (e.g., anemia, kidney disease) can affect A1C accuracy.
