Abstract
A host antigen-specific antibody testing system and method. The a ternary complex of the antigen, a ligand-bound anti-host IgM, and a non-host anti-antigen IgG detector conjugate selectively form a quaternary complex with host antibodies, wherein the host antibodies and IgG compete for the antigen, and the IgM binds the host antibodies. The quaternary complex is retained by an immobilized IgM ligand binding agent, and any residual ternary is retained by a later encountered immobilized anti-non-host IgG. If sufficient host antibodies have a high affinity for the antigen, the complex is detected at the quaternary complex detection region based on the presence of the detector, and if there are insufficient high affinity host antibodies, the ternary complex migrates past the quaternary complex detection region and is retained and detected at a control region.
