I went to the doctors today as I have had a constant headache for 2 weeks along with constant dry mouth/thirst, increase in liquid intake (and therefore expulsion!) and a bit of blurred vision. I am going to have a fasting blood test tomorrow morning and I was wondering how long it would normally take from this point to having a diagnosis one way or another?
I hadn't really thought of diabetes as a possibility until this morning and must admit it has freaked me out a bit.
Depending on the result, they may decide that it plus your symptoms are enough to diagnose diabetes.
But they should really send you for a glucose tolerance test. This involves another fasting blood test, followed by a drink containing a measured amount of glucose. Another blood test is taken 2 hours later. The bg levels in each test are compared. This is the gold standard test - and you should contact your GP asap to get the result.
Thanks for your replies. Had the test on Friday, they seemed to take a hell of a lot of blood, 5 different tubes of the stuff! Have been told I can phone for the results in the middle of next week, so just the anxious few days til Wednesday now.
