Immuno-chromatographic diagnosis means for respectively, simultaneously and specifically detecting and/or quantifying a plurality of analytes present in an essentially liquid sample comprising: - at least one reaction mixture containing recognition biological molecules and/or competitive ligands labelled with at least one visualisation molecule; and - at least one recovery system in the form of a solid support to which are bonded competitive ligands and/or recognition biological molecules at distinct and known recovery locations (4 and 5) which are arranged according to a two-dimensional matrix arrangement, so as to identify, by the localisation of said recovery locations (4 and 5) on said support, said analytes present in said sample, said diagnosis means being characterised in that, a) said two-dimensional matrix arrangement is defined according to a system of coordinates having a first coordinate and a second coordinate, such that each recovery location bonded on said solid support makes it possible to identify a distinct analyte and with, for one same coordinate X, several recovery locations each comprising different recognition biological molecules or competitive ligands, arranged along different coordinates Y and, with, for one same coordinate Y, several recovery locations each comprising different recognition biological molecules or competitive ligands, arranged along different coordinates X; b) for the detection and/or the quantification of a given analyte, a diagnosis couple consisting of a competitive ligand and a recognition biological molecule is present, such that said recognition biological molecule is found in said reaction mixture and said competitive ligand is bonded at at least one recovery location or conversely; c) said at least one visualisation molecule is a molecule which is detectable in fluorescence; and d) said reaction mixture is present in a container, said container being separate from said recovery system; the interaction of the reaction mixture with the sample to be analysed being focalised in said container separate from said recovery system in such a way that the sample interacts completely with the reaction mixture before the liquid thus obtained, formed from the reaction mixture and from the sample, is in contact with the solid support and therefore with the recovery locations, and e) said recovery system comprises at least 5 distinct recovery locations intended for respectively, simultaneously and specifically detect and/or quantify at least 5 distinct analytes present in a sample, and at least one recovery location intended for a control and/or a calibrator location. - at least one reaction mixture containing recognition biological molecules and/or competitive ligands labelled with at least one visualisation molecule;
