Abstract
A sensor, and methods of making, for determining the concentration of an analyte, such as glucose, 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 may include an insertion monitoring trace to determine correct positioning of the sensor in a connector. The sensor is calibration-adjusted, eliminating the need for a user to enter a calibration code or for the meter to read a calibration code.

23. A method of making a test sensor adapted to assist in determining the concentration of an analyte in a fluid sample, the method comprising the acts of:
-
attaching a first substrate to a second substrate to form a test sensor, the test sensor having a first end comprising a sample chamber, located between the first and second substrates, adapted to receive the fluid sample and a second opposing end adapted to be placed into a meter; and physically altering the sample chamber of the test sensor such that the shape of the test sensor corresponds to auto-calibration information, wherein physically altering the sample chamber comprises decreasing a volume of the sample chamber. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30)

31. A method of making a test sensor adapted to assist in determining the concentration of an analyte in a fluid sample, the method comprising the acts of:
-
attaching a first substrate to a second substrate to form a test sensor, the test sensor having a first end comprising a sample chamber, located between the first and second substrates, adapted to receive the fluid sample and a second opposing end adapted to be placed into a meter; and forming at least one cutout in the sample chamber such that the shape, dimensions and/or number of the at least one cutout corresponds to auto-calibration information, wherein forming at least one cutout in the sample chamber comprises decreasing a volume of the sample chamber. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
