What is eA1c?

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 SGmmol/L + 2.59)/1.59
Reference: Nathan DM, Kuenen J, Borg R, Zheng H, Schoenfeld D, Heine RJ for the A1c-Derived Average Glucose (ADAG). Study Group: Translating the hemoglobin A1c assay into estimated average glucose values. Diabetes Care 2008, 31:1473-8.
