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.

Abstract
An auto-calibration system for diagnostic test strips is described for presenting data individually carried on each test strip readable by a diagnostic meter. The carried data may include an embedded code relating to data particular to that individual strip. The data is presented so as to be read by a meter associated with the diagnostic test strip in order to avoid manually inputting the information.

6. A method of making a plurality of test strips, said method comprising:
-
forming a plurality of test strip structures on one sheet, each of said test strip structures including; a sample chamber; an electrically insulating base layer; and a conductive pattern formed on said sheet 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; disposing the electrically insulating material at least over a portion of the distal conductive region of each strip such that the apertures expose a pattern of the underlying distal conductive region on each strip to at least partially form a distinct machine-readable code representative of data particular to the test strip; and separating said test strip structures into said plurality of test strips. - View Dependent Claims (7, 8, 9, 10, 11)
