A dispensing mechanism is adapted to eject a test sensor from a cartridge opening formed in a cartridge containing test sensors. The dispensing mechanism comprises a gear rack, a gear, and a wheel. The gear rack includes a first portion and a second portion located generally parallel to one another. The second portion of the gear rack includes a first plurality of teeth. The gear includes a second plurality of teeth that are adapted to be engaged by the first plurality of teeth upon movement of the gear rack. The wheel is operatively engaged by the gear and is adapted to dispense the test sensor from the cartridge opening and to seal the cartridge opening. The movement of the gear rack in a first direction causes the gear to rotate causing the wheel to rotate. The rotation of the wheel dispenses the test sensor through the cartridge opening.

According to one embodiment of the present invention, an optical-based test sensor for use in the determination of an analyte in a liquid sample is disclosed. The test sensor includes a base, a polymer carrier, and a test membrane. The base has a capillary channel formed in a surface of the base that is adapted to move a liquid sample from an inlet to a reaction area formed in the base. The polymer carrier has a lower surface adhered to the surface of the base and is disposed over at least a portion of the capillary channel. The test membrane, which contains a reagent, is adhered to the lower surface of the polymer carrier and extends from the polymer carrier into the reaction area.
