9. A method of reducing time for stabilizing an analyte sensor having a plurality of electrodes inserted into a patient's body to provide accurate measurement of an analyte level in the patient's bodily fluid, the method comprising:
applying a first anodic current through an electrode of the plurality of electrodes for a first time period, wherein the electrode of the plurality of electrodes was inserted into the patient's subcutaneous layer through the patient's skin;
applying a first cathodic current through the electrode of the plurality of electrodes for a second time period;
measuring an electrical characteristic of the analyte sensor to obtain a first electrical characteristic measurement;
determining that the first electrical characteristic measurement does not meet a predetermined criterion which indicates sensor stabilization;
applying a second anodic current through the electrode of the plurality of electrodes for a third time period;
applying a second cathodic current through the electrode of the plurality of electrodes for a fourth time period;
measuring the electrical characteristic of the analyte sensor to obtain a second electrical characteristic measurement;
determining that the second electrical characteristic measurement does not meet the predetermined criterion;
applying a third anodic current through the electrode of the plurality of electrodes for a fifth time period;
applying a third cathodic current through the electrode of the plurality of electrodes for a sixth time period;
measuring the electrical characteristic of the analyte sensor to obtain a third electrical characteristic measurement;
determining that the third electrical characteristic measurement meets the predetermined criterion; and
measuring the analyte level in the patient's bodily fluid with the plurality of electrodes.
