Doesn't sound like this man had a full work up for diabetes, but I don't really know him. He needs to look up type 2 diabetes on the net, and become an informed consumer.

Glucose tolerance testing is a bit different from fasting blood glucose, but the glycated hemoglobin test is the best one...but certainly a fasting blood glucose should be done, on more than one occassion before diabetes is suggested or treated. I agree with glenntaj....

I gotta go skywatch and see if I can catch a glimpse of a twister!!!
(Don't worry if it gets really bad, I have my little hole in the basement, where me and my family and my beloved pets go hide...)
