should you fast before an a1c test

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, and fasting is not required because it is not affected by short-term changes in blood sugar. However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting, so always follow your healthcare provider's instructions.
