What is claimed is: 1. A continuous glucose monitoring system configured for measuring glucose concentration in a host, the system comprising:a continuous glucose sensor comprising a first working electrode disposed beneath an active enzymatic portion of a membrane system and configured to generate a first signal, and a second working electrode disposed beneath an inactive-enzymatic or a non-enzymatic portion of the membrane system and configured to generate a second signal, wherein the membrane system is configured to substantially reduce interfering species from reaching the first working electrode and the second working electrode; andelectronics configured to process the first signal and the second signal to produce a glucose signal that is substantially without signal contribution from interfering species, and to monitor the second signal for a change in amplitude above a threshold.
