A1c is a test that measures your average blood sugar level over the past 2 to 3 months. Your doctor may refer to it by other names — including the glycated hemoglobin, glycosylated hemoglobin, hemoglobin A1c or HbA1c test.
The higher your A1c level, the greater the risk for diabetes complications. Most adults with diabetes should aim for an A1c below 7%.
Talk to your doctor about how often to get an A1c test (usually at least twice a year).know
