ABSTRACT:
This invention relates to a lateral flow immunochromatographic assay device without a plastic housing. The assay includes a sample receiving region, analyte detection region and end region all made of porous material and capable of lateral flow. The analyte detection region includes labeling reagents, a capture reagent and a control reagent. The back of the porous material is laminated with a semi-rigid material with adequate mechanical strength. The top is partially covered with a thin plastic material so as to leave a portion of the sample receiving region exposed for sample application.
