Abstract
A method of high sensitivity immunoassay characterized by inclusion of processes (A), (B), (C) and (D) described below. PA0 Process (A): A process of binding of a solid carrier and a complex comprising the specific antibody or antigenic substance to be assayed in the test solution and one or more active components. PA0 Process (B): A process of dissociating said complex from the solid carrier. PA0 Process (C): A process of binding this complex to another solid carrier. PA0 Process (D): A process of assay for the complex on the solid carrier mentioned in the description of process (C) above. Permitting rapid, high sensitive immunoassay irrespective of whether the subject of assay is an antibody or an antigen, the method of the present invention is very useful for quick diagnosis of various diseases.
