Estimated A1c: Your estimated A1c level (also called HbA1c) is based on available
Sensor glucose data from the last 90 days. The more data available, the better
your estimation will be. However, the estimated level may not match your A1c
measured in a laboratory * . A1c can be used as an indicator of how well your
glucose levels have been controlled and may be used to monitor your diabetes
treatment regimen.
* The formula is based on the published reference, which compared average Sensor glucose and
laboratory-measured A1c:
A1c = (Avg SG + 2.59)/1.59
% mmol/L
