The Hemoglobin A1C (HbA1c) test is a common blood test used to measure your average blood sugar levels over the past 2-3 months. Here’s how it’s done:
- Blood Sample Collection: A healthcare professional will draw a small blood sample, usually from your arm or finger.
- Lab Analysis: The blood sample is sent to a lab where it is analyzed to determine the percentage of hemoglobin that is coated with sugar (glycated hemoglobin).
- No Fasting Required: Unlike some other blood sugar tests, you do not need to fast before taking an A1C test.
A1C Results Interpretation
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
This test is crucial for diagnosing prediabetes and diabetes, as well as monitoring how well your diabetes is being managed over time.
