Hi and welcome, I noticed they only done a fasting glucose test [ twice]which can be pretty useless in diagnosing prediabetes and diabetes 2, it is not unusual for prediabetics & diabetics to have normal fasting levels but once tested properly with a 3 -5 hour glucose tolerance test it can show a complete differant story, I was told I didn't have any signs of diabetes after a fasting glucose test but my neuro sent me for a glucose tolerance test and it turned out I was prediabtic, the cause of my nerve damage.

just a thought
good luck
Brian
