1. A method for continuous glucose sensing, the method comprising:
- generating a glucose signal associated with a glucose concentration in a host using a continuous glucose sensor;
measuring a sensitivity change of the continuous glucose sensor over a time period; and
determining using electronic circuitry, a stability of the continuous glucose sensor based on the measured sensitivity change, wherein the continuous glucose sensor comprises an electrode, and wherein measuring the sensitivity change comprises switching, cycling or pulsing a voltage applied to the electrode and evaluating a response to the applied voltage.

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.
