People with diabetes are also more likely to check their blood glucose more often when they are low (for example, first thing in the morning and before meals), so the average of readings on their meter is likely to be lower than their eAG.

Monitoring measures your blood glucose at a moment in time, whereas eAG/A1C represent an average of your glucose levels 24 hours a day, including times when people are less likely to check their blood sugar (for example, post-meal periods of higher blood sugar). The catch is that eAG/A1C is not the same average glucose level as the average of the readings on your meter. The difference between eAG/A1C and the average on your monitor eAG may help you understand your A1C value because eAG is reported as the same unit (mg/dL) that you see through self-monitoring on your meter or continuous glucose monitor (CGM). Your health care provider may report your A1C test result as eAG, or 'average glucose,' which directly correlates to your A1C.

Showing you how healthy choices can make a difference in diabetes control.

Judging whether a treatment plan is working.

Confirming self-testing results or blood test results by the doctor.

The A1C test can help you manage your diabetes by: Neither a single day's blood test results nor a single game's batting record gives the same big picture. In some ways, the A1C test is like a baseball player's season batting average: it tells you about a person's overall success.

The results give you and your diabetes care team a good idea of how well your diabetes treatment plan is working. The A1C test gives you a picture of your average blood glucose (blood sugar) control for the past two to three months. What is the difference between eAG and the average on my monitor?
