My question is about whether labs have different reference values because of the reagents used in processing. My lab report shows an A1C value of 6, and the lab normal range shows up to 6.2. I understand that normal values are usually less than 5.7, but in this case, can 6 be considered normal since the lab range shows up to 6.2? I understand fasting is high, but please restrict your answer to differences in lab normal ranges.
