Abstract: PURPOSE: To form a novel assay by employing an application pad containing a diffusive indicator which can migrate from the application pad to a chromatograph substance thereby combining several elements. CONSTITUTION: The equipment for assay employs a chromatograph substance 2 which can cause migration of a liquid, and an application pad 1. The application pad 1 controls the test sample flow to chromatograph substance 2, filter the test sample and mixes an assay reagent. The assay reagent is taken into the application pad 1 and chromatograph substance 2 and produces a detectable signal when an analyte is present. Results of assay can be indicated qualitatively and quantitatively by changing the position on chromatograph substance 2 containing the reagent.
