1. An analyte monitoring system, the system comprising:

  • an analyte sensor;

    a processor coupled to the sensor and configured to provide sensor data indicative of a concentration of glucose measured by the analyte sensor in a subcutaneous tissue of a host; and

    a user interface configured to provide real-time glucose information based on calibrated sensor data to a user, wherein the system is configured to calibrate the analyte sensor using reference data from a reference analyte monitor, wherein the calibration is allowed when an absolute rate of change of a calculated glucose concentration is less than about 4 mg/dL/min, and wherein the calibration is suspended when the absolute rate of change of the calculated glucose concentration is greater than about 4 mg/dL/min.
