No, you do not need to fast before taking an A1C test. The A1C test measures your average blood sugar levels over the past 2-3 months, so 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 confirm with your healthcare provider.
