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 glucose sensor is configured for transcutaneous implantation; and

    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 for a first time period, to calibrate sensor data using a glucose concentration measured by a reference glucose monitor operatively linked to the electronics module so as to generate real-time glucose readings from the sensor data and the calibration;

    wherein the electronics module is further configured to detect an approaching clinical risk and to activate an alarm based at least in part on the detection, and wherein the detection comprises predicting potential glucose concentration for a second time period based at least in part on both an extrapolation of real time glucose readings and on a variation analysis.
