1. A method for processing data from an electrochemical glucose sensor, the method comprising:

  • applying a voltage to an electrochemical glucose sensor configured to measure a glucose concentration of a biological sample of a host, wherein applying the voltage comprises at least one process selected from the group consisting of switching a voltage applied to the electrochemical glucose sensor, cycling a voltage applied to the electrochemical glucose sensor, and pulsing a voltage applied to the electrochemical glucose sensor;

    measuring a signal response of the electrochemical glucose sensor responsive to the at least one process; and

    detecting, using a processor, a signal artifact based on the signal response of the electrochemical glucose sensor to the switching, cycling, or pulsing of the applied voltage, wherein the signal artifact is associated with at least one condition selected from the group consisting of ischemia, a pH change, a temperature change, a change in available electrode surface area, and an interfering species.
