A sensor dispensing instrument adapted to handle a sensor pack containing a plurality of sensors and to perform a test using one of the sensors. The sensor dispensing instrument includes an outer housing and a mechanical mechanism contained therein for rotating the sensor pack and ejecting one of the sensors from the sensor pack and through a sensor slot on the housing. The mechanical mechanism of the sensor dispensing instrument is operated by first moving a disk drive pusher in a first direction to rotate the sensor pack, and then moving the disk drive pusher in a second direction to eject a sensor from the sensor cavity and through the sensor slot.
