1. A glucose monitoring system comprising:

  • a transcutaneous glucose sensor comprising;

    an in vivo portion configured to be inserted into a body of a host; and

    an ex vivo portion configured to remain outside of the body of the host; and

    a processor programmed to calibrate sensor data based at least in part on prior calibration information generated before insertion of the transcutaneous glucose sensor in the host, wherein the sensor data is associated with a glucose concentration of the host, wherein the prior calibration information comprises prior sensitivity information associated with the transcutaneous glucose sensor, wherein the prior calibration information is associated with a sensor code, wherein the sensor code is located in or on a packaging holding the transcutaneous glucose sensor, wherein the processor is programmed to calibrate the sensor data without a need for a reference analyte concentration measurement obtained after insertion of the in vivo portion of the transcutaneous glucose sensor.
