No, the 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 that has glucose attached to it. Unlike fasting blood glucose tests, you can take the A1C test at any time of the day without special preparation.
However, your doctor may order additional tests (e.g., cholesterol) alongside the A1C test that might require fasting. Always confirm with your healthcare provider before the test.
