ABSTRACT:
A test strip for a rapid immunoassay containing specific immunochemical reagent zones (7, 8, 9) is described. The test strip (10) has a backing sheet (1) and attached thereto a receiving end pad (3) and at a distance therefrom a finishing end pad (5). A test membrane (2) is provided between said pads (3, 5). Said membrane (2) is positioned in parallel relationship to said backing (1) at a distance therefrom so that said backing (1) and said membrane (2) limit between themselves an air gap (4) which is open at its edges. Said gap (4) functions as a sheltered reaction chamber for the immunolgical reaction taking place as a liquid is made to flow through said membrane (2). The test strip is simple to manufacture by lamination and easy to use and it is suitable for both diagnostic and environmental immunoassays.
