1. A method, comprising:

  • retrieving stored analyte sensor data;

    receiving analyte sensor data from an analyte sensor;

    receiving reference measurement values associated with an analyte level;

    determining sensitivity values based on the retrieved stored analyte sensor data, the received analyte sensor data and the reference measurement values;

    determining a sensitivity parameter of the analyte sensor based on the determined sensitivity values; and

    performing a probability analysis of the determined sensitivity parameter to determine a presence of a signal attenuation condition of the analyte sensor.
