Estimated Average Glucose
Estimated Average Glucose (eAG) translates your HbA1c result into the same units you see on a glucose meter (mg/dL or mmol/L). It is a calculated value derived from a formula, not a separate blood measurement.
eAG can make your HbA1c easier to relate to the day-to-day glucose numbers you may already track. Seeing your average expressed in familiar units helps connect a long-term marker to the readings you experience at home. It represents the same underlying information as HbA1c, just presented differently.
A higher eAG mirrors a higher HbA1c and suggests your average blood sugar has been elevated over recent months. Because it is calculated directly from HbA1c, the same conditions that affect HbA1c accuracy also carry into eAG. Your clinician interprets it in that broader context.
A lower eAG reflects a lower HbA1c and generally points to average blood sugar in a healthy range over recent months.
Since eAG is derived from HbA1c, aim for the eAG that corresponds to your personal HbA1c goal. Your clinician can tell you which target range fits you.
