    • A fluid flow test device comprising: a chromatography path of aqueous wicking material on which is deposited at an upstream site at a selected delivery time an aqueous biological sample to be tested for the presence or absence of a target material; a capture material bound to the wicking material at a test site downstream of the upstream site, the capture material having a functionality that binds to a first locus on the target material upon wicking of the target material downstream to the test site; a visual label material having a functionality that binds to a second locus on the target material, the chromatography path having a site upstream of the test site at which the visual label material is begun to wick at a predetermined point in time after the first delivery time such that the visual label material does not intermix with the aqueous biological sample within the chromatography path.
    • 一种流体流动测试装置,包括:水性芯吸材料的色谱路径,其上在选定的递送时间在上游位置沉积待测试的水性生物样品以存在或不存在目标材料; 所述捕获材料在所述上游部位的下游的测试部位与所述芯吸材料结合,所述捕获材料具有在所述靶材料下游向所述测试部位芯吸的目标材料上与所述靶材料上的第一位点结合的功能; 具有与目标材料上的第二位点结合的功能的视觉标签材料,色谱路径具有在第一次传送时间之后的预定时间点,视觉标签材料开始吸收的测试部位上游的位置 使得视觉标签材料不与色谱路径内的水性生物样品混合。
