Hi Ruth, the lab our doctor's office uses is Quest Diagnostics. On their lab report the only information is by parameters for what's "normal". So, Fasting Glucose is "65 - 99 mg/dL", and the A1C is "non-diabetic: <6.0%". So you see, my point is to know just what 6.0 is to them? If there's no "industry" standard as to what is considered, then we're in the dark. Two sources I found says 6.0 = 120; another one says 6.0 = 136. Big difference. Why should there be a completely different measure? Why not simply use the blood glucose number?
