1. An continuous glucose monitoring system configured for measuring glucose in a host, the system comprising:

  • a continuous glucose sensor comprising;

    a first working electrode configured to generate a first signal indicative of glucose and non-glucose related electroactive compounds having a first oxidation potential; and

    a second working electrode configured to generate a second signal indicative of non-glucose related electroactive compounds having the first oxidation potential; and

    electronics configured to process the first signal and the second signal;

    wherein the sensor further comprises at least two mechanisms configured to substantially block or substantially eliminate noise in the sensor signal, the mechanisms comprising a first mechanism disposed on the sensor and configured to reduce or substantially block interferants from reaching the first working electrode and the second working electrode, and a second mechanism in the electronics comprising programming configured to process the first signal to substantially eliminate a signal associated with the non-glucose related electroactive compounds therefrom.
