ABSTRACT:
The present invention relates to an immunoassay for antibodies against an infectious agent. The present invention also relates to the use of the immunoassay and a kit for performing the immunoassay of the present invention. The immunoassay for antibodies against an infectious agent relates to a method comprising: i. incubating a sample suspected of containing said antibodies with immobilized antigen of the infectious agent and free labeled antigen of the infectious agent; ii. separating immobilized components from non-immobilized components; iii. incubating the immobilized components with further free labeled antigen of the infectious agent and removing non-immobilized components; and iv. determining the amount of labeled antigen immobilized, wherein the amount of label is indicative of the amount of said antibodies present in the sample.
