The invention relates to a method for production of a multi-layer analysis element (10) for liquid samples, with at least one test field (6) for the analysis of the liquid samples, in which method an analysis element blank (1) composed of at least two superposed material layers (14) is made available. The multi-layer analysis element (10) or a constituent part of the multi-layer analysis element (10) is cut out from the analysis element blank (1) by means of laser radiation. The laser radiation cuts through different material layers (14) in at least two areas (20, 21, 22) and has a laser power which is effective for said cutting and which is varied as a function of the thickness and the material of the different material layers (14) to be cut in the areas (20, 21, 22).
