Do you fast for hemoglobin A1C?

No, fasting is not required for a hemoglobin A1C test. The A1C test measures your average blood sugar levels over the past 2-3 months, so it does not depend on whether you have eaten recently. However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting, so always confirm with your healthcare provider before the test.
