Do you need to fast for a hemoglobin A1C?

No, you do not need to fast before taking a hemoglobin A1C test. The A1C test measures your average blood sugar levels over the past 2-3 months, and it is not affected by recent meals. However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting, so always follow your healthcare provider's instructions.
