Further A1C data clarification

 There are two institutional pathways for obtaining A1C: 100 mg/dl and the 126 mg/dl 1-That based on the 100-level reading for glucose at anyone time in the blood being the 6.0 equivalent , as exemplified by the following:

2. The 126-level reading for glucose at anyone time in the blood being the 6.0 equivalent eAG/A1C Conversion Calculator.

As from this an April 2021 result taken at 1215pm, that I expect came-by the time of day-to be a non-fasting lab-with me having eaten something earlier that morning. By the readings, an A1C of 5.4 would be within the normal range. By calculation I'd have to have a Glu=108: something my every third day readings have been under.
 I suggest my latest labs of November and December at langley 633rd Hospital be checked for the Glucose number.
ADA is recommending the use of a new term in diabetes management, estimated average glucose, or eAG. Health care providers can now report A1C results to patients using the same units (mg/dl or mmol/l) that patients see routinely in blood glucose measurements. The calculator and information below describe the ADAG Study that defined the relationship between A1C and eAG and how eAG can be used to help improve the discussion of glucose control with patients.

The relationship between A1C and eAG is described by the formula 28.7 X A1C – 46.7 = eAG or A1C=eAG+46.7/28.7.
-Plus an extrapolated formula that can be used for either 100 mg/dl or 126 mg/dl: Alt.A1C=(Pres.Glu/100)*5.6 [5.6 equaling what one would weigh-155lbs].
A1C  eAG %    mg/dl mmol/
 6.0      126           7.0
6.5       140           7.8
7         154            8.6
7.5      169            9.4
