Abstract:
1. A method of making an electrochemical test sensor adapted to assist in determining information relating to an analyte in a fluid sample, the method comprising the acts of: providing a base; providing a second layer to assist in forming a channel; providing a plurality of electrodes on the base, the plurality of electrodes including a working electrode and a counter electrode; providing a working conductive lead that is electrically connected to the working electrode; providing a counter conductive lead that is electrically connected to the counter electrode; providing a reagent formed in the channel; and providing auto-calibration information of the test sensor by forming a plurality of auto-calibration segments to be connected to one of the following: the working conductive lead, the counter conductive lead, or neither of the conductive leads, and wherein at least one of the plurality of auto-calibration segments is connected to the working conductive lead and at least one of the plurality of auto-calibration segments is connected to the counter conductive lead; wherein each of a first plurality of auto-calibration areas is located between a first portion of the working conductive lead and a portion of the counter conductive lead and each of a second plurality of auto-calibration areas is located between a second portion of the working conductive lead and a portion of the counter conductive lead, the location of the first plurality of auto-calibration areas being different from the second plurality of auto-calibration areas; wherein each of the first plurality of auto-calibration areas is located on an opposing side of the counter conductive lead as compared to each of the second plurality of auto-calibration areas; wherein the working conductive lead extends along at least a portion of two peripheries of the electrochemical test sensor.
