Definitely check a new blood meter. However, are you on any new medications - especially prednisone? Have you done scans of the pancreas - where insulin is produced? If you are younger than 30 years old - it could possibly be type I diabetes. Most are diagnosed as a child - but the limit for type I is 30 years old. Many develop type II - even from a young age. Your A1C is for the past 3 months - and they do correlate that with an approx. blood glucose. Your A1C is pre-diabetic. Watch diet, but check out other causes as well. Good luck.
