An analytical system for detecting an analyte in a body fluid comprises a disposable integrated puncturing and analyzing element and a reusable analytical system. The integrated element includes a puncturing element having a tip for generating a puncture wound in a body part and an elongated flat test strip having a top side and a bottom side. The integrated element is held in a holder such that, in a sample application position of the test strip, the top side of the test strip is facing upward. A sample application area for manual application of a drop exiting from the puncture wound of the body part is provided on the top side of the test strip such that, in the sample application position, the drop is applied to the sample application area from directly above.
