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, wherein the measured sensitivity change is not based on a reference glucose measurement from a reference glucose monitor; and

    determining, using electronic circuitry, a stability of the continuous glucose sensor based on the measured sensitivity change; and

    calibrating the glucose signal using the measured sensitivity change.
