Usually a fasting reading of 127 twice or an A1c of 6.5 is considered Diabetic. If you have never had any sugar problems in the past I would ask for another test as it could have been an error. Best time to do a fasting is in the a.m. after an 8-10 hr. fasting overnight.
An A1c usually tells what your sugar levels have been running over the last 3-4 months. If this was done by the insurance company and not your own Dr. I would call your Dr. and ask what he/she thinks you should do.
Best of luck...JJ...
