1. A method of calibrating glucose monitor data, the method comprising the steps of:

  • sampling glucose monitor data from a sensor at a predetermined sampling rate;

    deriving interval values from the sampled glucose monitor data over a predetermined interval rate;

    applying clipping limits to the derived interval values;

    deriving at least one glucose monitor data point by averaging the derived interval values at a predetermined memory storage rate;

    obtaining from another blood glucose measuring device at least one blood glucose reference reading that is temporally associated with at least one glucose monitor data point;

    calibrating the sampled glucose monitor data using the at least one blood glucose reference reading and the corresponding at least one glucose monitor data point.
