Emilia Klapp, Nutrition & Dietetics, answeredThe hemoglobin A1c test involves taking a single drop of blood, which is either analyzed at a laboratory or at a doctors’ office. You don’t need to worry about fasting; food eaten on the same day won’t affect the result. People with diabetes usually undergo this test every three months. If their blood-sugar level is under control, twice a year may be enough.
