A1c is a test that shows the average level of blood sugar in the last 2 or 3 months. People who have diabetes should have this test on a regular basis to see if their blood sugar levels have remained within the ideal range or not. This test is also used to diagnose diabetes.
The results of the A1c test show the average blood sugar level over time. The result is reported as a percentage. Your goal is to keep the hemoglobin A1c level as close as possible to the desired level. You and your doctor will work together to set the optimum level safe for you.
The result of your A1c test can also be used to calculate your average blood sugar level. This is called the estimated average glucose (eAG). Your eAG and A1c show the same in two different ways. Both help you know about your average blood sugar level in the last 2 or 3 months.
The table below shows the A1c along with the estimated average glucose.
