ABSTRACT:
The invention relates to a technology by which antibodies directed to sources of infection in body fluids can be assayed with high accuracy, expediency and specificity. More particularly, the invention provides an antibody immunoassay method in which the antigen-antibody reaction between a target antibody in a sample and an assay antigen is conducted in the presence of anE. colicomponent and an antibody assay method which comprises using a reagent having a specific affinity for the Fc region of an antibody IgG as the antibody assay reagent. The invention further provides an antibody assay device comprising a solid-phase support having at least (a) a first region to which a sample is applied and (b) a second region where the antibody in the sample is reacted as disposed in such an arrangement that the sample is wicked from the first region to the second region and a labeling means for detection of the result of the reaction in the second region, characterized in that the (b) second region is provided with (i) a test site in which a ligand for capturing the target antibody to be assayed is immobilized and (ii) a control site in which a ligand for capturing an arbitrary antibody occurring in the sample is immobilized.
