The HbA1c test gives an indication of your blood glucose control over the previous 2–3 months and is an important part of your diabetes-care regimen. Because the red blood cells in a blood sample used for an HbA1c test are a mixture of cells of different ages, the test gives a “weighted” average of recent blood glucose levels. Even if you haven’t met your HbA1c goal yet, you might be pleased to know that just about any decrease in blood glucose levels can help. Exactly how often your HbA1c level should be checked depends on your degree of blood glucose control and your physician’s judgment. Because everyone’s health situation is unique, you need to work with your health-care team to set an HbA1c goal that will work best for you.
