8 doctors agree

In brief: Below 5.7

Current guidelines suggest a hba1c of 6.
5 or higher can be used to diagnose diabetes, and that levels of 5.7 to 6.4 can indicate "pre-diabetes". There is still some debate about whether using an A1c is the best way to look for diabetes. In general we identify and diagnose diabetes too late in our country and many times damage already exists when the diagnosis is first given.
