Someone who is not diabetic will have about five percent of their hemoglobin glycated. This means that if your A1C is below 5.7, you don’t have to worry. A normal A1C level is below 5.7 percent; 6.5 percent or above indicates diabetes; 5.7 to 6.4 percent is prediabetes.To monitor your overall glucose control, diabetics should have an A1C at least twice a year.ome people may have a blood glucose test that indicates diabetes, while their A1C is normal, or vice versa. Before making a diagnosis of diabetes, your doctor should repeat the tests. Some people may even get false results if they’re severely anemic, are in kidney failure, or have liver disease.
