1. A continuous glucose monitoring system, comprising:

  • a sensor configured to detect one or more glucose levels;

    a sensor control unit operatively coupled to the sensor, the sensor control unit configured to receive signals corresponding to the detected one or more glucose levels from the sensor, the sensor control unit including electronics to convert the received signals to a predetermined format, the sensor control unit further configured to transmit the converted signals corresponding to the detected one or more glucose levels; and

    a receiver operatively coupled to the sensor control unit configured to receive the transmitted signals corresponding to the detected one or more glucose levels;

    wherein the electronics include logic to compare consecutive signals from the sensor to determine if they differ by more than a threshold level, and if the difference is greater than the threshold level for one signal or over a period of time or for a predetermined number of signals within a period of time, the electronics is configured to generate an output notification.
