Clinical Use
Estimated average glucose (eAG) is an estimated average of your blood sugar (glucose) levels over a period of 2 to 3 months. eAG is calculated directly from your A1C results. Because it uses the same units as home meters, eAG makes it easier for people to understand their A1C values relative to their home blood sugar readings.
