The A1C level, also known as the hemoglobin A1C or HbA1c test, measures your average blood sugar levels over the past 2 to 3 months. It provides a broader picture of your blood sugar control compared to daily glucose tests, which only show a snapshot of your blood sugar at a single point in time.
Key Points:
- Normal A1C: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
How It Works:
- Glucose in your blood attaches to hemoglobin, a protein in red blood cells.
- The A1C test measures the percentage of red blood cells that have glucose-coated hemoglobin.
- Since red blood cells regenerate every 3 months, the A1C test reflects your average blood sugar over that period.
Why It Matters:
- Diagnosis: Used to diagnose prediabetes and diabetes.
- Monitoring: Helps track how well you’re managing your diabetes over time.
- Goals: For most people with diabetes, the target A1C is below 7%, but your doctor may set a different goal based on your health.
Factors Affecting A1C Accuracy:
- Conditions like anemia, kidney failure, or certain medications can affect results.
- Always discuss any unusual results with your healthcare provider.
