Abstract: The test elements are provided that are adapted to detect at least one analyte in a sample. At least some of the test elements are provided with a defect marking which contains information about defectiveness of the test elements. The test elements include at least one radiation-sensitive material. The test elements are exposed to at least one radiation, the radiation being adapted to induce marking in the form of at least one optically detectable change in the radiation-sensitive material.

Abstract: A method is provided for producing a microfluidic system on a polymer surface, wherein at least one portion of the polymer surface is irradiated by laser light in a targeted fashion for the spatially-resolved modification of the wettability of the portion of the polymer surface by a liquid sample.

Abstract: Disclosed is a process for manufacturing packaged lancets. The steps of the process include providing a tape comprising a plurality of lancets comprising a lancet tip and a lancet body, enveloping at least the lancet tip with at least one foil, whereby the at least one foil forms a first and a second portion that overlap at least partly, and sealing the at least one foil with a laser beam at least at the edges of the first and second portion of the overlapping foil.

Abstract: A method is provided for producing an analytical element comprising at least one test field for analyzing a liquid sample, wherein provision is made for a carrier on which a polymer fabric is arranged. At least one portion of the polymer fabric is irradiated with UV laser light and thereby hydrophobized.

Abstract: The invention relates to a method for production of a multi-layer analysis element for liquid samples, with at least one test field for the analysis of the liquid samples, in which method an analysis element blank composed of at least two superposed material layers is made available. The multi-layer analysis element or a constituent part of the multi-layer analysis element is cut out from the analysis element blank by means of laser radiation. The laser radiation cuts through different material layers in at least two areas and has a laser power which is effective for the cutting and which is varied as a function of the thickness and the material of the different material layers to be cut in the areas.
