Hello, I've never been concerned about diabetes before as my fasting blood glucose levels have always been under 100. However, my last fasting glucose test as well as my husband's were both high (mine 127, his 140). The doctor had us return for A1c tests which were in the normal range (mine 5.6, his 5.5). Based on that, the doctor assumed we had eaten something before the fasting test and said, 'see you in 3 months'. But we didn't eat anything.
