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.

1-22. (canceled)
A method of making a calibration-adjusted 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 sensor, the sensor having a first end comprising a sample chamber, the sample chamber comprising at least one electrode and 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 sensor and an area of the at least one electrode, which corresponds to auto-calibration information, wherein physically altering comprises decreasing the area of the at least one electrode and produces a calibration-adjusted sensor,
- wherein the auto-calibration information is obtained from a test sensor.
