Anyway, this one doctor has said that he sees it in his practice all the time, i.e., patients whose fasting glucose
and who also test normal
with the glucose
tolerance test, however, their A1c is over 5.7. Also, I read that people whose blood is low in iron can also test falsely high on their A1c. I checked out my blood results and my iron level is barely above the low cutoff for normal. So, I wonder if that has anything to do with my higher A1c.
