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

  • receiving sensor data from a glucose sensor for a time period;

    evaluating, using one or more processors, the sensor data to detect signal artifacts, the evaluating comprising performing a first derivative analysis of the sensor data and performing a second derivative analysis of the sensor data;

    determining, using the one or more processors, a level of confidence based on the evaluation;

    generating insulin administration instructions based on the sensor data;

    outputting an indication of the level of confidence; and

    administering, using the insulin administration device, insulin to a host based on the insulin administration instructions.
