1. An electrochemical analyte sensor for measuring an analyte in a host, the sensor comprising:

  • at least one electroactive surface; and

    a membrane system disposed on the electroactive surface, wherein the membrane system comprises an interference domain comprising at least one cellulosic derivative, wherein the interference domain is configured to resist passage therethrough of at least one interferent, and wherein an equivalent glucose signal response of the at least one interferent is less than about 30 mg/dL.
