A 'one step' device for the detection of analytein clinical assays is disclosed. A visible label comprising a visible moiety and a ligand that binds to or competes with analyte is contained in a fluid conducting membrane or prefilter; and the analyte and associated ligand are conducted by the flow of sample into a detection zone. The detection zone contains a capture reagent that binds to label or to analyte bound to label.
