1. A method, comprising:

  • subcutaneously positioning at least a portion of an in vivo glucose sensor;

    obtaining a signal from the in vivo glucose sensor;

    determining if the obtained signal is acceptable for use in determining a sensitivity factor based on a first predetermined criteria;

    obtaining a calibration measurement;

    determining if the obtained calibration measurement is acceptable for use in determining the sensitivity factor based on a second predetermined criteria;

    determining the sensitivity factor using the obtained signal and the obtained calibration measurement when it is determined that the obtained signal and the obtained calibration measurement are acceptable for use in determining the sensitivity factor; and

    determining a suitability of the sensitivity factor for calibration of the in vivo glucose sensor by evaluating whether the sensitivity factor is within a predetermined range assigned to a production lot of the in vivo glucose sensor.
