    • Test carrier for analysis of a sample liquid with the help of a specific binding reaction of two bioaffine binding partners, one of which is contained in the sample and one in the reagent system of the test carrier, with several capillary-active test zones (11-16; 21-25) arranged substantially next to one another on a base layer (2). The test zones are in liquid contact with one another so that they form a liquid transport path (20, 30) along which a liquid flows, driven by capillary forces, from a start zone (11, 21), a reaction thereby taking place between the first binding partner and the reagent system containing the second reaction partner, which reaction leads to a labelled species characteristic for the desired analysis. A third binding partner specific for the first binding partner sets as capturing reagent which is so arranged in a zone of the liquid transport path (20, 30) and is so measured with regard to the amount used that it binds a part of the first binding partner and thereby removes it from the reaction leading to the characteristic labelled species. A process for the analysis of a liquid sample with the above test carrier is also provided.
    • 借助于两个生物亚硫酸结合配偶体的特异性结合反应(其中一个包含在样品中,一个在测试载体的试剂系统中)与样品液体分离的测试载体,具有几个毛细管活性测试区(11 -16; 21-25),其基本上彼此相邻布置在基底层(2)上。 测试区彼此液体接触,使得它们形成液体输送路径(20,30),液体沿着该液体输送路径(20,30)从毛细作用力从起始区域(11,21)流动,由此发生反应 第一结合配偶体和含有第二反应伴侣的试剂系统,该反应导致所需分析的标记物质特征。 特定于第一结合伴侣的第三结合配偶体设置为捕获试剂,其被布置在液体输送路径(20,30)的区域中,并且相对于所使用的量如此测量,其结合了第一结合物的一部分 从而将其从导致特征标记物种的反应中除去。 还提供了使用上述测试载体分析液体样品的方法。
