Hi, I don't have diabetes but I went to the docs for a blood test on everything. Well, they called me back to do a fasting blood glucose test because the last blood test (non fasting) came back with high sugar in my blood. Well, I fasted for 13 hours, had a blood test and my results came back that I was not diabetic. The high sugar level must have been from my breakfast. I was relieved at this however I do have lots of symptoms of diabetes and I was wondering, is it possible that I still could be diabetic. I'm just worried because I have a lot of symptoms but surely the GPs know what they're doing?
