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.
