    • The invention concerns a portable device for reading a fluorescent-labelled, membrane based assay, to detect the presence of an analyte in a sample. The portable device comprises a light sealed housing which includes a receiving member to receive a membrane based assay. The light sealed housing comprises a first light source for illuminating a first portion of the membrane with light, a first photodetector, a light guide and a microprocessor. The first photodetector is operable to detect fluoresced light emitted by an excited fluorescent label captured by a reagent laid down in the first portion of the membrane and to measure an intensity of the fluoresced light. The light guide guides illuminated light from the first light source to the first portion of the membrane and guides fluoresced light emitted by the excited fluorescent label to the first photodetector. The microprocessor is operable to process the measured intensity of the fluoresced light to determine whether the analyte is present.
    • 本发明涉及用于读取荧光标记的基于膜的测定法以检测样品中分析物的存在的便携式设备。 便携式装置包括一个光密封的外壳,它包括一个用于接收基于膜的测定的接收构件。 光密封壳体包括用于用光照亮膜的第一部分的第一光源,第一光电检测器,光导和微处理器。 第一光电检测器可操作以检测由放置在膜的第一部分中的试剂捕获的激发的荧光标记发射的荧光,并测量荧光的强度。 光引导件将来自第一光源的光照射到膜的第一部分,并将由激发的荧光标记发射的荧光的光引导到第一光电检测器。 微处理器可操作地处理所测量的荧光的强度以确定分析物是否存在。
