Your readings sound very normal to me - random samples in a non diabetics should be between 3.2 and 7.7 (I'm not a doctor but that is the range the lab I work at uses) I have recently heard of doctors interpreting a borderline result as GD, rather than doing the extended test as they believe that that test will give the same results. In alot of borderline cases, further testing actually shows that there is no GD. If you haven't already been retested with the longer test I would suggest that you ask your doctor for it, or for them to show you the results from your last test that shows very abnormal results. Good luck!!
