An A1C at or above what level is used to diagnose diabetes?

6.5% or higher is in the diabetes range.

  1. 5.0%
  2. 5.7%
  3. 6.5% ✔

Why: An A1C of 6.5% or higher is in the diabetes range, while 5.7% is where prediabetes starts. Doctors usually confirm a diagnosis with a repeat test.

Huh, didn't know that: You don't have to fast or drink anything special before an A1C test.

The dad joke
Why was the equal sign so humble? It knew it wasn't less than or greater than anyone else.
