1. A method for determining a stability of substantially continuous glucose sensor, the method comprising:

  • receiving reference data from a reference glucose monitor, including a reference data point;

    receiving a data stream from a continuous glucose sensor, including one or more sensor data points;

    pairing the reference data point with a substantially time-corresponding sensor data point of said one or more sensor data points, whereby a matched data pair is formed;

    determining a sensitivity of the continuous glucose sensor based on the matched data pair;

    determining, using electronic circuitry, a level of stability of the continuous glucose sensor, wherein the level of stability is based on a variability of the sensitivity over time; and

    prohibiting display of real-time glucose information in response to the level of stability not meeting one or more predetermined criteria.
