1. In a glucose sensing system comprising a glucose sensor configured for producing an output representative of glucose concentration in a host and processing circuitry configured to process the output, a method for processing data from the output, the method comprising:

  • generating at least one data stream from the glucose sensor output;

    detecting signal loss, wherein detecting signal loss comprises monitoring the data stream to identify a negative rate of change and determining that the negative rate of change exceeds a predetermined threshold;

    generating an estimated data stream or data stream portion to reduce or replace the signal loss; and

    outputting to an external device or displaying the at least one estimated data stream or data stream portion.
