Here is how the the ADAG [American Diabetes Association Guideline] formula to convert ones
A1c to eAG [estimated Average
Glucose], or what your daily average
glucose has been for the past 3 months.
28.7 X A1c – 46.7 = eAG
An example of this is an A1c of 6%. The calculation for this would be:
28.7 X 6 – 46.7 = 126 mg/dl
for an estimated average glucose of 126 mg/dl.
As you will see, 126 mg/dl is the beginning point of t2 diabetes.
