Is an A1C of 5.9 good or bad?

[hlthe2b]

1. Normal is below 5.7

5.7 to 6.1 is considered compatible findings for "Pre-Diabetic" and 6.5 is considered "Diabetic."

Within that 5.7-6.1 range, the higher it is the higher your risk for developing Type 2 Diabetes.

That said, the fact that yours has come down from 6.4 is meaningful (good). Talk to your physician for any more on this as your concomitant conditions, medications, and risk history are relevant.
