Abstract

A sensor-dispensing instrument is adapted to determine an analyte concentration of a fluid and comprises a body, a cap, a cartridge, a test-sensor receptacle, and a sensor-advancement mechanism. The cap is adapted to move between an open position and a closed position. The cap and body are adapted to correspond with each other to form the closed position. The cartridge contains a plurality of test sensors. The cartridge is located substantially within the cap. The sensor-advancement mechanism is adapted to advance the plurality of test sensors, one at a time, to a position that allows a user to manually remove the test sensor and place the test sensor in the test-sensor receptacle. The sensor-dispensing instrument may also include a lancing device including a lancet.
