It has been known for the same blood sample to be sent to two different labs and 2 different numbers come back. My understanding is that the really important numbers are the ones I see on my meter one and two (or more) hours after eating. It sounds as if you have not been testing at these times. IMO it would be a good idea to do so. If the numbers are higher than you like, your readings can then guide you as to how to modify your diet to improve them. Interestingly, I have recently been shocked to have the mirror image of your discrepancy between A1c and fasting bg. For the whole month of May my fasting bg was 5 or less, and my after meal readings were quite low, yet my latest A1c had gone up to 38 which I think equates to an average of 6.6!!! I almost never see a reading as high as 6. I think the difference may be partly down to the fact that my red blood cells were slightly above normal. If you had other blood tests at the same time as your A1c, you might like to check if anything similar has happened for you. Raised haemoglobin can raise the A1c and lower haemoglobin can lower it. I put no weight on the categories of pre-diabetic etc. As you say, the cutoffs vary from country to country. What does harm is too much sugar in the blood. That is where it is so helpful to test at home. Any one reading may be inaccurate, but because we can test so often, we get a much better idea of what is going on than with a one-off test like the A1c.</blockquote>
