A lancing device comprises a main housing, a movable housing and a pushbutton. The main housing encloses a portion of a lancing mechanism. The lancing mechanism includes a lancet holder attached to a shaft. The lancet holder receives a lancet and has a slot formed therein. The lancing mechanism moves between a rest position, a cocked position, and a puncture position. The movable housing is adjacent to the main housing. The movable housing moves from a rest position to a cocking position and a lancet-release position. The pushbutton allows the lancing mechanism to move from the cocked position to the puncture position upon depression of the pushbutton. The pushbutton includes a lancet-release tab that extends into the slot formed in the lancet holder and engages the lancet. The lancet is released from the lancet holder in response to the continued depression of the pushbutton and the movable housing is moved from the rest position to the lancet-release position.
