Blood A1C of 5.8 - opinions seem to differ

[Qadgop_the_Mercotan]

The consensus at UpToDate.com (with which I agree on this matter) is as follows:

We suggest annual follow-up testing when the fasting glucose is 100 to 125 mg/dL, or A1C is 5.7 to 6.4 percent. The diagnosis of diabetes is confirmed if two consecutive A1C levels are ≥6.5 percent, two consecutive FPG levels are >126 mg/dL, or if both the A1C and fasting glucose are above their diagnostic thresholds.

So based on your A1C alone, you’re in the ‘glucose intolerance’ zone.

I don’t understand why an endocrinologist would base their diagnosis of diabetes on a Hgb A1C range from 5 to 7.
