A1C range. An A1C between 5.7 and 6.4 percent signals prediabetes. And type 2 diabetes is diagnosed when the A1C is over 6.5 percent. For many people with type 2 diabetes, the goal is to lower A1C levels to a healthier percentage. By the way, after-meal numbers below 180 can be “normal”. This number can vary wildly. A normal A1C value range for a non-diabetic patient is between 4.5 and 6 percent, according to Mayo Clinic. If A1C levels measure above 6.5 percent on two separate occasions, a doctor may diagnose diabetes. A1C levels correspond to average blood sugar levels, explains Mayo Clinic.
