The cartridge further comprises a plurality of walls forming a cavity therein. The cavity is adapted to include the plurality of test sensors. At least one of the plurality of walls forms at least one aperture. The cartridge further comprises a lid adapted to enclose the cavity. The cartridge further comprises a locking feature adapted to lock the lid to one or more of the walls. The locking feature is adapted to be disengaged by the at least one aperture receiving a projection of an analyte-testing instrument. ## Claims ### Claim 1 A test-sensor cartridge comprising: a plurality of test sensors adapted to assist in determining an analyte concentration of a fluid sample; a plurality of walls forming a cavity therein, the cavity being adapted to include the plurality of test sensors, at least one of the plurality of walls forming at least one aperture; a lid adapted to enclose the cavity; and a locking feature adapted to lock the lid to one or more of the walls, the locking feature being adapted to be disengaged by the at least one aperture receiving a projection of an analyte-testing instrument. ### Claim 2 (depends on 1) The cartridge of claim 1, wherein the locking feature includes a latch coupled to the cartridge and a corresponding notch coupled to the lid. ### Claim 3 (depends on 1) The cartridge of claim 1, wherein the locking feature includes a tab portion extending into the aperture. ### Claim 4 (depends on 1) The cartridge of claim 1, wherein the aperture extends completely through the cartridge. ### Claim 5 (depends on 1) The cartridge of claim 1, wherein the aperture is adapted to receive a first projection of a first analyte-testing instrument with which the cartridge is compatible and wherein the aperture may not receive a second projection of a second analyte-testing instrument with which the cartridge is incompatible. ### Claim 6 (depends on 1) The cartridge of claim 1, wherein the cartridge further includes a coding feature positioned such that the coding feature may be read by the analyte-testing instrument when the at least one opening receives the projection. ### Claim 7 (depends on 6) The cartridge of claim 6, wherein the coding feature is located on a surface of the lid adjacent to the cavity and the projection includes a feature for reading the coding feature. ### Claim 8 (depends on 6) The cartridge of claim 6, wherein the coding feature is located on a surface of the lid adjacent to the cavity and the projection includes reading device. ### Claim 9 (depends on 6) The cartridge of claim 6, wherein the aperture is adapted to receive a first projection of a first analyte-testing instrument with which the cartridge is compatible and wherein the aperture may not receive a second projection of a second analyte-testing instrument with which the cartridge is incompatible. ### Claim 10 A test-sensor cartridge comprising: a plurality of test sensors adapted to assist in determining an analyte concentration of a fluid sample; a plurality of walls forming a cavity therein, the cavity including the plurality of test sensors, at least one of the walls forming at least one aperture; and a lid adapted to enclose the cavity, the lid including a side portion having a locking extending from the side portion, the locking feature having a tab portion positioned within the at least one aperture, the locking feature being adapted to be disengaged by the at least one aperture receiving a projection of an analyte-testing instrument. ### Claim 11 (depends on 10) The cartridge of claim 10, further comprising a coding feature positioned on at least one of the plurality of walls or the lid. ### Claim 12 (depends on 11) The cartridge of claim 11, wherein the coding feature is configured to be read by a reading device positioned on the analyte-testing instrument. ### Claim 13 (depends on 10) The cartridge of claim 10, wherein the lid is a screw-on type lid. ### Claim 14 (depends on 13) The cartridge of claim 13, wherein movement of the lid is obstructed by the portion of the locking feature positioned within the at least one aperture. ### Claim 15 (depends on 10) The cartridge of claim 10, wherein at least a portion of the locking feature is detachable. ### Claim 16 (depends on 10) The cartridge of claim 10, wherein the aperture is adapted to receive a first projection of a first analyte-testing instrument with which the cartridge is compatible and wherein the aperture is unable to receive a second projection of a second analyte-testing instrument with which the cartridge is incompatible. ### Claim 17 An analyte-testing system for determining an amount of an analyte in a fluid test sample, the analyte-testing system comprising: a test-sensor cartridge including a plurality of test sensors, a plurality of walls forming a cavity therein, the cavity being adapted to include the plurality of test sensors, at least one of the walls forming at least one aperture, a lid adapted to enclose the cavity, and a locking feature adapted to lock the lid to one or more of the walls, the locking feature including a side portion extending from the lid and a tab portion positioned within the at least one aperture, at least a portion of the locking feature being positioned within the at least one aperture; and an analyte-testing instrument including a body portion, at least one opening formed in the body portion, the at least one opening being configured to receive one of the plurality of test sensors, and at least one projection extending from the body portion, the locking feature being adapted to be disengaged by the at least one aperture receiving the at least one projection of the analyte-testing instrument. ### Claim 18 (depends on 17) The analyte-testing system of claim 17, wherein at least a portion of the locking feature is detachable. ### Claim 19 (depends on 17) The analyte-testing system of claim 17, the test-sensor cartridge further including a coding feature positioned on at least one of the walls or the lid, the coding feature being adapted to be read by a reading device positioned on the analyte-testing instrument. ### Claim 20 (depends on 17) The analyte-testing system of claim 17, wherein the aperture is unable to receive a second projection of a second analyte-testing instrument with which the cartridge is incompatible.
