Abstract
Processes, reagents and test kits for the qualitative and/or quantitative determination of an immunochemically reactive component, in which one or more labelled components are used, that are obtained by direct or indirect coupling of such a component or components to particles of an aqueous dispersion of a hydrophobic dye or pigment, or of polymer nuclei coated with such a dye or pigment. During the reaction or after an adequate reaction time the nature and/or the quantity of the dye is determined in the test medium, or optionally after a separation of the bound and free labelled components in one of the fractions.
