Abstract
For the qualitative or/and quantitative detection of a substance to be determined in a test sample with the aid of an immunoassay or nucleic acid hybridization assay the following components are used: a) a capture reagent which enables a specific detection of the substance to be determined by means of two different binding sites 1) if desired together with further test components and 2) is bound or is capable of binding to an active solid phase via a specific binding pair one partner of which is linked to the capture reagent and the second partner of which is coupled to an active solid phase b) an active solid phase and c) an inactive solid phase which substantially corresponds to the active solid phase but to which the capture reagent cannot bind, wherein the test sample is either firstly brought into contact with the inactive solid phase alone and only later with the active solid phase, or is simultaneously brought into contact with the active and inactive solid phase during which the capture reagent and if desired further test components are either present from the start or are only added later and the substance to be determined is detected.
