The A1C test is a simple blood test. You don't need to fast for the A1C test, so you can eat and drink normally before the test.

Fasting is not needed for A1C assessment and no acute perturbations (e.g., stress, diet, exercise) affect A1C. Plasma glucose levels are not stable but rather vary throughout the day, mainly in postprandial periods.
Are you supposed to fast for ac1 hemoglobin blood test?
Health care professionals can use the A1C test alone or in combination with other diabetes tests to diagnose type 2 diabetes and prediabetes. You don't have to fast before having your blood drawn for an A1C test, which means that blood can be drawn for the test at any time of the day.
