Abstract
A sensor, and methods of making, for determining the concentration of an analyte, such as glucose or lactate, in a biological fluid such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. The sensor includes a working electrode and a counter electrode, and can include an insertion monitoring trace to determine correct positioning of the sensor in a connector.

-19. (canceled)
An electrochemical test sensor being adapted to determine an analyte concentration of a fluid sample, the electrochemical test sensor comprising:
- a base including a first base end and an opposing second base end;
- a plurality of electrodes being formed on the base at or near the first end, the plurality of electrodes including a working electrode and a counter electrode;
- and
- at least one reagent being positioned at or near the first end so as to contact the fluid sample,
- wherein the electrochemical test sensor includes a first end and an opposing second end, the test sensor having an auto-calibration area, the auto-calibration area having markings in a form of a pattern corresponding to auto-calibration information.
A test sensor being adapted to determine an analyte concentration of a fluid sample, the optical test sensor comprising:
- a base including a first base end and an opposing second base end;
- a fluid-receiving area being adapted to receive a fluid sample, the fluid-receiving area being located near or at the first base end;
- at least one reagent being positioned to contact the fluid sample in the fluid-receiving area, the at least one reagent assisting in optically determining the analyte concentration of the fluid sample;
- wherein the test sensor includes a first end and an opposing second end, the test sensor having an auto-calibration area, the auto-calibration area having markings in a form of a pattern corresponding to auto-calibration information.
