1. A method of making a test strip, said method comprising:

  • providing a sample chamber;

    providing an electrically insulating base layer; and

    providing a conductive pattern formed on the base layer including a plurality of electrodes, a plurality of electrical strip contacts, conductive traces electrically connecting the electrodes to at least some of the electrical strip contacts, and a distinct distal conductive region provided distal to the electrical strip contacts;

    providing an electrically insulating material including a pattern of apertures; and

    disposing the electrically insulating material over at least a portion of the distal conductive region such that the apertures expose a pattern of the underlying distal conductive region to at least partially form a distinct machine-readable code representative of data particular to the test strip.
