The results of the A1C-Derived Average Glucose study (ADAG), published in Diabetes Care, have affirmed the existence of a linear relationship between A1C and average blood glucose levels.
In light of the study results, ADA is recommending the use of a new term in diabetes management, estimated average glucose, 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 relationship between A1C and eAG is described by the formula 28.7 X A1C – 46.7 = eAG.
