does a hemoglobin a1c have 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, so it is not affected by recent meals. However, your doctor may order additional tests (like cholesterol) that require fasting, so always follow your healthcare provider's instructions.

Key Points:

• No fasting required for the A1C test.
• It reflects long-term blood sugar control, not immediate levels.
• Other tests done at the same time may require fasting.
