    • 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 phaseb) an active solid phase andc) 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.
    • 为了通过免疫测定或核酸杂交测定法在待测样品中定性或定量检测待测物质,使用以下组分:a)使物质特异性检测的捕获试剂 通过两个不同的结合位点确定1)如果需要,连同另外的测试组分,和2)结合或能够通过特异性结合对结合活性固相,其中一个配偶体与捕获试剂连接,第二个 其配合物与活性固相偶联b)活性固相,和c)基本上对应于活性固相但不与捕获试剂结合的惰性固相,其中测试样品首先接触 单独使用无活性固相,仅在随后的活性固相中,或者同时与活性和非活性固相接触,在此期间 e捕获试剂,如果需要,进一步的测试组分从一开始就存在或者仅在后面加入,并且检测待测物质。
