Method for performing a rapid chemical test on liquid samples by micro-titration, micro-chromatography or other methods of dry chemistry and methods for production is effected in that the relevant chemical analysis processes become more accurate by having partial sampling take place according to the principal of vectorial capillary flow addition, which is achieved by at least two opposed flow directions in a capillary-active device with at least two inlet openings for the sample, where the whole test device is bathed in the sample and accurate quantitative evaluation is performed by means of an analyte-concentration-proportional area or distance measurement and where several analytes can be determined simultaneously with a test device having several differently prepared capillary zones. An Independent claim is also included for production of the test device by dissolving the relevant analytical reagents in a vaporizable solvent, impregnating a porous support with the solution, drying the support, laminating the support between two liquid-impermeable adhesive films, and punching out disks from the laminate.
