should a1c be fasting

No, the A1C test does not require fasting. Unlike other blood sugar tests (such as fasting plasma glucose), the A1C test measures your average blood sugar levels over the past 2-3 months. It reflects the percentage of hemoglobin in your red blood cells that has glucose attached to it.

• No fasting needed: You can eat and drink normally before the test.
• Other tests: If your doctor orders additional tests (e.g., cholesterol or fasting glucose), you may need to fast for those.

Always follow your healthcare provider's instructions for any tests.
