The invention relates to a method for calibrating an analyte-measurement device that is used to evaluate a concentration of analyte in bodily fluid at or from a measurement site in a body. The method involves measuring a concentration, or calibration concentration, of an analyte in blood from an “off-finger” calibration site, and calibrating the analyte-measurement device based on that calibration concentration. The invention also relates to a device, system, or kit for measuring a concentration of an analyte in a body, which employs a calibration device for adjusting analyte concentration measured in bodily fluid based on an analyte concentration measured in blood from an “off-finger” calibration site.

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; anddetermining 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. 2. The method of claim 1, further comprising calibrating the in vivo glucose sensor only if the sensitivity factor is determined to be within the predetermined range. 3. The method of claim 1, further comprising disabling a calibration routine to calibrate the in vivo glucose sensor if the sensitivity factor is determined to not be within the predetermined range. 4. The method of claim 1, further comprising: determining an average sensitivity factor by averaging a plurality of data pairs, each data pair including a corresponding obtained signal and calibration measurement; andcalibrating the in vivo glucose sensor based on the average sensitivity factor. 5. The method of claim 4, wherein the average sensitivity factor is derived from a weighted average of the plurality of data pairs. 6. The method of claim 5, wherein the weighted average is a weighted average of all previously obtained data pairs. 7. The method of claim 1, wherein a sample for the calibration measurement is less than about 1 microliter. 8. The method of claim 1, wherein a sample for the calibration measurement is less than about 0.5 microliters. 9. The method of claim 1, wherein a sample for the calibration measurement is less than about 0.2 microliters. 10. The method of claim 1, further comprising evaluating the obtained calibration measurement for calibration acceptability. 11. The method of claim 10, wherein the evaluating the calibration measurement for calibration acceptability comprises evaluating whether the calibration measurement is within a predetermined range of analyte concentrations. 12. The method of claim 11, wherein the predetermined range comprises about 60 mg/dL to about 350 mg/dL. 13. The method of claim 1, wherein the in vivo glucose sensor includes at least one working electrode comprising an analyte-responsive enzyme and a mediator. 14. The method of claim 13, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode. 15. The method of claim 14, wherein at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.
