Test-sensor cartridge

A method of modifying testing parameters of an analyte-testing instrument, the method comprising the acts of:

• providing a test-sensor cartridge including a plurality of walls forming a cavity therein, the cavity being adapted to include a plurality of test sensors, at least one of the walls forming at least one aperture, the cavity being enclosed by a lid having a locking feature adapted to lock the lid to one or more of the walls, the test sensors being adapted to assist in the determination of a concentration of an analyte in a fluid sample, at least one of the lid or the walls having a coding feature being positioned thereon;
• providing an analyte-testing instrument having at least one projection located thereon, the analyte-testing instrument including a reading device;
• disengaging the locking feature by contacting the cartridge to the analyte-testing instrument such that the at least one projection mates with the at least one aperture;
• reading the coding feature using the reading device;
• modifying at least one testing parameter of the analyte-testing instrument based on information received by reading the coding feature.
