What Is the Target Range for Hemoglobin A1C?
The target is to keep your A1C level under 7 percent. The risk of complications increases considerably when A1C levels rise above 8 percent. The optimal range for hemoglobin A1C is 4-6 percent. To watch your overall glucose control, an A1C test should be done at least twice a year at a minimum, or as often as your health care provider advises.
