Diabetics—and pre-diabetics—need to know how their blood sugar levels are doing over time. The A1C test measures a person’s amount of glucose in hemoglobin in the blood over the past three months, giving doctors a good idea of how effectively the person has been controlling their blood sugar over time and how their treatment plan is working.
The A1C test shows if a person’s blood glucose levels are normal or elevated. The higher the result, the more likely a person will experience health problems, so the goal is to get the A1C result down to “7%” or less. You can check an A1C chart to see the different numbers, and what’s normal versus what’s high and requires a patient to make changes or face problems.
People who are pre-diabetic or diabetic should take an A1C test twice a year or more. Ask your doctor or health care provider for details about Medicare’s coverage of the A1C test.
