does hemoglobin a1c need to be fasting

No, the Hemoglobin A1C (HbA1c) test does not require fasting. This test measures your average blood sugar levels over the past 2-3 months by assessing the percentage of hemoglobin coated with sugar. Since it reflects long-term glucose levels, fasting is not necessary.

However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting. Always confirm with your healthcare provider before the test.
