ABSTRACT OF THE DISCLOSURE A diagnostic device for immuno-chemical quantification includes a capillary-containing, porous carrier, e.g., a strip of cellulose fibre, starch polyvinyl chloride or polyvinyl chloride-silica, with antibodies bound thereto by adsorption or covalent bonding. Immuno-chemical quantification is effected by a method involving adding a sample containing an antigen to be quantified to the device, initiating a capillary migration, and effecting an assay of antigen-containing areas of the device by the addition of antibodies bound to a color indicator, e.g. a fluorescent compound such as fluoresceine isocyanate or an enzyme capable of catalyzing a color-developing reaction.
