A puncturing system includes a carrier tape carrying multiple lancets and having position marks, a housing comprising a conveying facility for positioning the lancets and a housing opening, a puncturing drive for accelerating a lancet positioned in a usage position, a storage medium for storing distance values that depend on distances between the lancets of the carrier tape and position marks allocated to the respective lancets, a sensor for detecting position marks in a detection position through which the position marks proceed upon motion of the carrier tape, and a control unit that controls the conveying facility. To position a lancet in the usage position, the control unit stops the conveying facility upon the carrier tape moving a positioning distance. The length of the positioning distance depends on the distance between the lancet to be positioned and the detected position mark and is determined by the control unit.

The present invention provides a puncturing system for withdrawing body fluid. The puncturing system comprises a disposable puncturing unit, which includes a needle element for piercing into skin and a puncturing depth reference element with a skin contact area. The system includes a puncturing instrument which has a puncturing drive, wherein the puncturing drive is coupled by a coupling mechanism to the puncturing unit for driving the needle element to a puncturing depth, the puncturing depth being determined by the distance in the piercing direction between the skin contact area and the position of the tip of the needle at a reversal point of the puncturing movement. The puncturing depth reference element is connected to the needle element such that the puncturing depth reference element moves with the needle element during at least part of the puncturing movement. The puncturing depth reference element has a defined longitudinal position in the piercing direction relative to the needle element at least at the reversal point of the puncturing movement.
