HI S.-
For the 1-Hr glucose test, the doctor's prefer a number below 140 mg/dl; although I've heard of some offices using 130 as the cut-off number. Anything from 140 to 180 typically results in having to take the 3-hr test. Anything over 180 and the doctor will most likely skip the test and head straight to management measures for GD.
It seems that more often than not the 1-Hr comes back with false positives.
Generally the 3-hr comes back fine. You need to "fail" two of the 4 draws (baseline plus 3 after the drink) to be classified as GD.
I would ask your doctor what their protocols are for failures. Mine indicated I would get to speak to a nutritionalist if I failed one or more and that they would try to develop a diet controled program for me if I failed mroe than 2 draws. They indicated that they do not like to prescribe insulin so I was glad to hear that.
Your best bet, relax, bring a book and try not to think about it.

PS. I passed my 3-hr.
