do i need to fast before a hba1c blood test

No, you do not need to fast before taking an HbA1c (hemoglobin A1c) blood test. The HbA1c test measures your average blood sugar levels over the past 2-3 months, and it is not affected by recent meals. However, your doctor may order additional tests (e.g., cholesterol or fasting glucose) that require fasting, so always confirm with your healthcare provider.
