1. A method for processing data from a glucose sensor, comprising:

  • receiving a signal from a glucose sensor;

    detecting signal artifacts in the signal, wherein detecting comprises evaluating the signal against one or more predetermined signal artifacts criteria;

    generating, using one or more processors, estimated glucose values based at least in part on the signal, wherein the generating is configured to be performed continually during a period of continuous glucose sensing; and

    replacing, using the one or more processors, at least some glucose sensor values associated with at least some signal artifacts using one or more of the estimated glucose values in response to detection of signal artifacts that meet the one or more predetermined signal artifacts criteria.
