Documentation:
The American Diabetes Association has recommended that laboratories report the eAG result as an adjunct to the A1c.
While the A1c result represents the average glucose over time, the eAG will be reported in the same units as daily self-monitoring glucose devices and may assist the patient’s ability to interpret the A1c.
For patients that may see an average glucose on their glucose meters, the eAG value may likely not match. People with diabetes are more likely to test more often when their glucose levels are low, while the eAG represents glucose levels continuously throughout the day including after meals when people are less likely to test. The eAG may help patients more directly see the difference between their individual meter readings and how they are doing with their glucose management overall.
