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.

Lab normal ranges can slightly vary, but medically, A1C of 6 is considered prediabetic. Even if your lab marks it as normal, aim to bring it below 5.7 with lifestyle changes. Repeat every 3 to 6 months and consult if it trends higher.

My reading for a non fasting glucose test is 145. The normal range is 70 to 140. Is this okay, or do I need to change my lifestyle and diet for a healthy, diabetes free life?
