1. A glucose sensor system for monitoring glucose concentration in a biological sample of a host, the system comprising:

  • a continuous glucose sensor configured to produce sensor data indicative of a host'"'"'s glucose concentration, wherein the continuous glucose sensor comprises a sensing region and a sensing membrane located over the sensing region, and wherein at least a portion of the continuous glucose sensor is configured for transcutaneous implantation;

    an electronics module configured to receive sensor data from the continuous glucose sensor, the electronics module comprising a processor configured to process sensor data received from the continuous glucose sensor and to calibrate sensor data using at least one glucose concentration measurement from a reference glucose monitor operatively linked to the electronics module; and

    a display;

    wherein the system is configured to display, on the display, glucose concentration information derived from the calibrated sensor data on a graph having a plurality of graphically distinct clinical risk zones, at least two of the clinical risk zones being incremented along a y-axis according to different glucose concentration scales.
