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.
