WHAT IS AN A1C?
Your Hemoglobin A1C is a measurement of your average blood glucose control for the last two to three months. About 50 percent of the value comes from the last 30 days.
Your A1C should be measured every three months, if your blood glucose targets are not being met or if you are making changes to your diabetes management.
Your A1C is an important measurement of your diabetes control, as well as before meal and after meal blood glucose levels.
