Even though your HbA1C seems to be a little high, HbA1C is not considered a diagnostic test for diabetes and there are different normal reference ranges in different labs.
At this time I would suggest that you have a 2-hour glucose tolerance test in a lab. If blood glucose at 2-hour is equal or more than 200 mg/dl, it will be considered indicative of diabetes while a value between 140-199 mg/dl would be considered impaired glucose tolerance (borderline diabetes). Value <140 mg/dl at 2-hour is normal.
Lifestyle modification, exercise and dietary changes should be considered the first step.
