do you mean that your 1 hour test was 137, or the fasting result of the 3 hour was 137? If the 1 hour was 137, that's pretty much borderline fail. depending on the doctor, it's even a pass because some use the threshold of 140 and some use 130. If you got a 137 fasting glucose on the 3 hour test, then yes, it's a bit high. I think that one needs to be below 100. Good luck with your 3 hour results!
I failed my 1 hr (my level was about 150ish) and just barely passed my 3 hour (I failed the 3 hour result and I barely passed the 2 hour result, by about 5 points). I have impaired glucose tolerance, which I knew about before hand.
