A lancet assembly comprising an elongated lancet and a plurality of cooperative members at least some of which are movable relative thereto so as to selectively orient the lancet in a covered position, operative position or protected position. The plurality of members each comprise at least one coded structure visually indicative of the lancet being in one of the aforementioned positions dependent at least in part on which one or more of the coded structures are predominantly observable. The coded structures may comprise color codings which may be visually distinguishable or visually indistinguishable from one another. Coded structures other than color codings may be utilized.
