How many blood tests to diagnose diabetes?

How many blood tests are needed to diagnose diabetes? I have recently had three fasting samples taken. The first two showed blood glucose levels in the diabetic range, 8.9 for the first and only just within the range for the second. The third was normal. My GP wrote ‘no action’ on this and so none was taken, but if only one fasting sample out of three was normal, might not this one sample be the ‘glitch’?

If you are really concerned ask him if he could do a Hb1c test which shows the average blood glucose level over the last 2-3 months and a glucose tolerance test. But it might be that knowing your full medical history and of course he might have already done the first one I mentioned that he does not think you have diabetes. In the mean time try to drink plenty watch what you eat especially ADDED sugar(Not things like the sugar present in fruit etc) and fat and exercise more if possible.
