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 small 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 percentages indicate higher average blood sugar levels.
- Frequency: For people with diabetes, the A1C test is typically done at least twice a year. If you have prediabetes or are at risk, your doctor may recommend testing every 1 to 2 years.
This test is a key tool for diagnosing and managing diabetes and prediabetes.
