An estimated average blood glucose derived from HbA1c.
Estimated average glucose (eAG) is a calculated value, not a separate blood test. It converts your HbA1c result into the average blood sugar level it reflects over the past two to three months, expressed in the same units as a glucose reading.
The formula is: eAG (mg/dL) = 28.7 × HbA1c (%) − 46.7. To express it in SI units, that result is divided by 18.0182 to give mmol/L.
HbA1c is reported as a percentage, which can be hard to relate to the day-to-day glucose numbers people see on a meter. eAG translates that percentage into a familiar average glucose value, making it easier to understand what your long-term control looks like.
A higher eAG means your average blood sugar has been running high, which over time raises the risk of diabetes complications. A lower eAG reflects tighter average control.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
These are interpretive translations of HbA1c, not separate targets:
Values are guidance based on the ADAG study and vary with the HbA1c assay. Your doctor sets individual targets.
eAG inherits the limits of HbA1c. Conditions that shorten red blood cell life, such as anaemia, recent blood loss, or certain haemoglobin variants, can make HbA1c and therefore eAG unreliable. It reflects an average and hides daily highs and lows.
Read alongside HbA1c itself and fasting glucose. eAG is most useful when interpreted with a clinician who knows your treatment targets.
