Patent Images
1. A method for processing data from a glucose sensor in a host, the method comprising:
- measuring a first signal associated with glucose and non-glucose related electroactive compounds, wherein the first signal is measured at a first electrode disposed beneath an active enzymatic portion of a membrane system;
measuring a second signal associated with at least one non-glucose related electroactive compound, wherein the second signal is measured at a second electrode disposed beneath a non-enzymatic portion of the membrane system; and
calculating, in an electronic device, a change in the second signal over a time period.

Abstract
Disclosed herein are systems and methods for calibrating a continuous analyte sensor, such as a continuous glucose sensor. One such system utilizes one or more electrodes to measure an additional analyte. Such measurements may provide a baseline or sensitivity measurement for use in calibrating the sensor. Furthermore, baseline and/or sensitivity measurements may be used to trigger events such as digital filtering of data or suspending display of data.
