Hi,
What was the reading that made your doc say you were diabetic?
Do you know what your HbA1c result is?
Your surgery should provide you with a print out of your results, if you ask.
Also, how long after eating did you test to get the 6.6 and 8.8 readings.
They are certainly not outside 'normal' non-d readings, but it all depends on timing.
Non diabetics can reach as high as 11mmol/l after food (depending on what that food is), but the key factor is that they don't stay that high for as long as a diabetic would.
