could the fasting blood glucose tolerance test have been wrong?

doctor said I have type 2, FGTT numbers were high, at least one of them I know was quite a bit over the line to qualify as diabetic, however, the first A1C was below 6! I had a second A1C and it was even lower than the first one, around 5.4 is there any chance the doctor was wrong? I am confused cause I keep reading how some doctors now go more by the A1C and others by the first test I had done. I don't hardly ever get high numbers. thanks!

My last Ac1 was 5.2, I have many lows to the point the Dr had to take me off diabetes meds off meds my numbers are 80 to 200 daily.

The fact that your A1c may be variable like that (if it was under 6 I would guess it would be 5.9 and 5.4 is only 0.5 difference) could be due to hypos ("lows").

My late wife would have Blood Glucose levels in the upper 200s to 300s for weeks because she needed to use corticosteroids for other diseases she had, yet she would have A1c of 6.0. When I asked her endo about that he said she must have had some mighty low hypos during those 3 months (and she most certainly did).

So A1c may not be an accurate way of deterrnining a Dx of diabetes. I would put more faith in the OGTT.

In some people, not very many , their diabetes does not show up very much in the A1c test. I would get a test done on other tests that test for diabetes. Either that, or your meter is off. ANNE
