A level of 5.7 to 6.4 percent indicates prediabetes, and people with diabetes have an A1C level at 6.5 percent or above. The American Diabetes Association provides a calculator that shows how A1C levels correlate to glucose levels. To monitor overall glucose control, people with diabetes should have an A1C test at least twice a year.
