1. A method of making a glucose concentration measuring system comprising:

  • measuring glucose sensitivity characteristics of a sample set of transcutaneous glucose sensors;

    manufacturing at least one transcutaneous glucose sensor, wherein the at least one transcutaneous glucose sensor comprises;

    an in vivo portion configured for insertion and existence within a living body of a host during sensor use; and

    an ex vivo portion configured to remain outside the living body of the host during sensor use, wherein the ex vivo portion is configured to operably connect to sensor electronics via contacts during sensor use;

    assigning information associated with a sensor sensitivity to the at least one transcutaneous glucose sensor based at least in part on the measurements of glucose sensitivity characteristics of the sample set of transcutaneous glucose sensors;

    storing the information associated with the sensor sensitivity in the sensor electronics;

    configuring the sensor electronics to receive sensor input signals; and

    configuring a processor to use the information associated with the sensor sensitivity to calibrate received sensor input signals after implantation of the at least one sensor in the host, without use of reference glucose concentration values from the host obtained after implantation of the at least one transcutaneous glucose sensor in the host.
