1. A method for processing sensor data, comprising:

  • receiving sensor data from a continuous glucose sensor, wherein the sensor data is indicative of a glucose concentration in a host;

    receiving reference data from a reference glucose monitor, wherein the reference data is indicative of a glucose concentration in the host;

    determining, using a processor module, a conversion function based on the sensor data and the reference data, wherein the conversion function comprises a sensitivity value and a baseline value;

    validating the conversion function based on predetermined calibration information, wherein the predetermined calibration information comprises sensitivity information and baseline information derived from in vivo testing of at least one other continuous glucose sensor or in vitro testing; and

    adjusting the conversion function in response to the validation failing a criterion, wherein the adjusting is without reference data obtained from an in vitro self-monitoring blood glucose test after implantation in vivo.
