Abstract:
A method for producing a device that detects the presence of an analyte in a urine stream, the method comprising the steps of:providing an assay material in one portion having a capture region for binding the analyte, and in another portion a urine sample receiving region;providing a casing defining:a hollow housing for receiving the assay material, said housing including an upper section co-joined to a lower section;a urine inlet port for permitting urine applied directly from a urine stream to enter the casing and to contact the urine sample receiving region of the assay material, and to travel by sorptive transport therefrom to said capture region of the assay material; anda window in said upper section spaced apart from the urine inlet port for viewing the capture region;enclosing the assay material within the casing; andmaking said upper section of said casing of transparent material for permitting a user, immediately after applying urine into said urine inlet port, to observe movement of urine and a reconstituted direct labeled reagent along a flow path of said assay material from proximate said urine sample region toward said capture region, to thereby determine that a test is working.
