Claim 35:
36. A method of making a glucose monitoring system comprising:
providing a transcutaneous electrochemical 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 the body of the host, wherein the in vivo portion of the transcutaneous electrochemical glucose sensor comprises an electrode and a membrane comprising glucose oxidase, and wherein the transcutaneous electrochemical glucose sensor is associated with an in vitro sensitivity to glucose;

applying a predictive relationship to the in vitro sensitivity to glucose to generate an in vivo sensitivity to glucose that is different from the in vitro sensitivity to glucose; and
providing a processor configured to calibrate data derived at least in part from in vivo measurements generated by the transcutaneous electrochemical glucose sensor after insertion of the in vivo portion of the transcutaneous electrochemical glucose sensor in the host, wherein the processor is configured to perform the calibrating based at least in part on the in vivo sensitivity to glucose generated by applying the predictive relationship, and wherein the processor is configured to perform the calibrating without requiring calibration information obtained from a reference glucose measurement after insertion of the transcutaneous electrochemical glucose sensor.
