Abstract
A process for the detection of an antigen or antibody in a specimen which process comprises: PA0 (a) contacting said specimen with a substrate having bound thereon a mixture of antigens and antibodies to said antigen or antibody in said specimen, said antibodies and said antigens bound to said substrate being separately bound to said substrate and not in the form of an immune complex, incubating the so-contacted substrate and washing the substrate; PA0 (b) contacting the washed material of step `a` with a radioactive material labeled or enzyme labeled antibody or antigen, incubating the so-contacted material and washing the same; and PA0 (c) effecting radioimmunoassay if said antibody or antigen is radioactive or enzyme labeled immunoassay is said antibody or antigen is enzyme labeled.
