No, the HbA1c (Hemoglobin A1c) test does not require fasting. It measures your average blood sugar levels over the past 2-3 months by assessing the percentage of hemoglobin coated with sugar. Unlike fasting blood glucose tests, you can take the HbA1c test at any time of the day, regardless of when you last ate.
However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting, so always confirm with your healthcare provider.
