The invention provides an immunochemical filter device and use thereof, said filter device comprising a filter material attached to a support member. The filter material comprises a labeled binding reagent, wherein said labeled binding reagent is released from the filter material into solution by migration of a liquid sample solution through the filter material. The mixture of the sample solution and the labeled specific binding reagent is transferred to an analyzer device comprising a porous carrier, preferably by expressing the mixture through an aperture, diffusible membrane or valve in the support member. Additionally the invention provides a method for determining the presence or absence of an analyte in a sample solution and further provides a kit comprising the filter device.
