Abstract (en)
[origin: WO8703691A1] Determination of whether or not a test substance, such as a pregnancy antigen (AG), is present by combining (1) the test substance (AG) with a first labeled material, e.g. a first enzyme labeled antibody (ABA-E1) in a vial (30). The resulting product is added (2) to a second labeled material, e.g. a second enzyme labeled antibody (ABA-E2), bound to a membrane (22) which overlays a porous member (21) both within a housing (10) to which a substrate is applied (3) from vial (40) to react with one of the labels and produce a reagent that in turn reacts with an indicator and the other label to provide a test indication such as a color change.
