The A1C test, also known as the hemoglobin A1C or HbA1c test, is a simple blood test that measures your average blood sugar levels over the past 2 to 3 months. Here’s how it works:
- Procedure: A healthcare professional will draw a blood sample from your arm or finger. No fasting is required before the test.
- Measurement: The test measures the percentage of your red blood cells that have sugar-coated hemoglobin. Higher blood sugar levels result in more sugar-coated hemoglobin.
- Frequency: The test is typically done in a doctor’s office or lab and is recommended for individuals over 45, or younger if they have risk factors for diabetes.
