1. An analyte monitoring system, comprising:

  • an analyte sensor in operative contact with an analyte, the sensor adapted to generate a plurality of data points associated with a monitored analyte concentration;

    an alarm associated with the monitored analyte concentration;

    a processor adapted to process the plurality of data points generated by the analyte sensor; and

    logic implemented by the processor to;

    determine whether a current data point of the plurality of data points is within a predetermined threshold zone, wherein if it is determined that the current data point is within the predetermined threshold zone, the logic implemented by the processor determines a rate of change of an analyte level based on the plurality of data points;

    determine if the rate of change indicates a projected glucose value exceeding an alarm threshold within a predetermined amount of time;

    perform a line fit analysis of a slope based on the plurality of data points associated with the monitored analyte concentration;

    assert the alarm associated with the monitored analyte concentration when the determined rate of change indicates that the projected glucose value will exceed the alarm threshold within the predetermined amount of time, and when the line fit analysis of the slope is not within an acceptable level; and

    control administration of a therapy based on the assertion of the alarm associated with the monitored analyte concentration.
