A healthy person ‘s A1C level is between 4 percent and 6 percent.
The American Diabetes Association recommends an A1C less than 7 percent for most adults with diabetes. ADA target ranges for children are age-specific: 7.5 to 8.5 percent for kids younger than 6, less than 8 percent for 6- to 12-year-olds, and less than 7.5 percent for teens from 13 to 19.
A1C targets aren’t cut and dried. For example, a person with diabetes and heart failure has a greater risk of death if his A1C is between 6.4 and 7.1 percent than if he maintains an A1C between 7.1 and 7.8. But if his glucose goes above 7.8, his risk rises again.
