The lancet unit (10) includes a lancet having a rod shaped body (12) disposed at one end in a lancet retaining member (18) and a sterile sharp tip (14) at the other end. The lancet unit (10) includes a movable sleeve (24) with an axial passageway (28) therethrough sized to receive the lancet body segment (20) which extends beyond the retaining member (18) coaxially therein. The sleeve (24) is movable longitudinally from an initial position for use of the lancet unit (10) where the sharp tip (14) of the lancet projects beyond the sleeve (24) to a protective position wherein the sleeve (24) surroundingly encloses and shields the contaminated tip (14) of the used lancet unit (10). The lancet unit (10) further includes a coupling member (32, 36) and a receiving opening (34) which matingly engage to fixedly secure the sleeve (24) in its protective position.
