1. An optical detection system for detecting the presence or quantity of an analyte residing in a test sample, said system comprising:

  • an optical reader that comprises an illumination source and a detector, said illumination source being capable of providing electromagnetic radiation and said detector being capable of registering a detection signal; and

    an assay device that includes a porous membrane having a first surface and an opposing second surface, said porous membrane being in communication with detection probes that are capable of producing said detection signal when contacted with said electromagnetic radiation, wherein said first surface of said porous membrane is carried by a support, said support having a thickness of from about 100 to about 5,000 micrometers, wherein said support is provided with an optically functional material that is selectively tailored to one or more optical properties of said optical reader.
