    a plurality of test sensors stacked in the cartridge housing;

    an instrument housing to removably receive the cartridge housing and the plurality of test sensors therein;

    a mechanical mechanism including a plate coupled to a spring, the mechanical mechanism being configured to engage and urge the plurality of test sensors stacked in the cartridge housing in a first direction;

    a pair of extensions positioned to guide the mechanical mechanism, the spring of the mechanical mechanism being positioned between the pair of extensions, the pair of extensions being detached from the plate; and

    a pusher assembly including a slider and a bar coupled to the slider, the slider being movable in a second direction generally perpendicular to the first direction between a first position and a second position, wherein movement of the slider from the first position to the second position causes the bar to engage one of the plurality of test sensors stacked in the cartridge housing and to urge that test sensor towards an exterior of the cartridge housing, wherein the bar is configured to engage a top one of the test sensors stacked in the cartridge without passing through a seal.
