Analysis system for determining an analyte in a body fluid, comprising - a disposable integrated sample acquisition and analysis element, which comprises a piercing element (7) having a tip (15) for generating a puncture wound in a body part and a flat test strip (6) having a sample receiving zone (10), into which a body fluid sample is transferred to perform an analysis, and - a reusable analysis instrument (2), comprising a coupling unit, which is adapted to couple an integrated sample acquisition and analysis element to a drive, by which a piercing movement of the piercing element (7) is driven, the piercing movement comprising a propulsion phase in which the piercing element (7) is moved on a puncture path in the puncture direction and a retraction phase in which the piercing element (7) is moved opposite to the puncture direction after reaching a reversal point of the piercing movement and further comprising a measuring and analysis unit (36) for measuring a measurement variable characteristic for the determination of the analyte and for determining a desired analysis result on the basis of the measurement. The sample receiving zone (10) of the test strip (6) is located on one of its flat sides (9), which forms a sample contact side (11). The piercing element (7) is located parallel to the test strip (6) and is movable on the movement path relative to the test strip (6) during at least a part of the puncture movement. The piercing element (7) is located adjacent to the sample contact side (11) of the test strip (6). It has a capillary channel (17), which has a sample inlet (23), through which the body fluid may enter into the capillary channel (17) after the piercing, and a sample outlet (24), through which the body fluid may exit from the capillary channel (17). The movement path of the piercing element (7) comprises a sample transfer position, in which the sample outlet (24) is adjacent to the sample receiving zone (10) of the test strip (6) in such a manner that the body fluid may be transferred from the capillary channel (17) through the sample outlet (24) to the sample receiving zone (10). |
