As glucose enters the bloodstream, it binds to hemoglobin, or glycates.The more glucose that enters the bloodstream, the higher the amount of glycated hemoglobin,â Dr. Dodell says. An A1C level below 5.7 percent is considered normal.An A1C between 5.7 and 6.4 percent signals pre-diabetes. Type 2 diabetes is diagnosed when the A1C is over 6.5 percent.
