Abstract
The invention concerns a process for the immunological determination of a specific antibody in a fluid sample. The process involves incubating the fluid sample in the presence of a solid phase with two antigens directed against the antibody whose presence is to be determined; the first antigen carries at least one marker group, while the second is either (a) bonded to the solid phase or (b) present in a form in which it can bond with the solid phase, and betrays the presence of the antibody being sought by showing the presence of the marker group in the solid phase and/or in the fluid phase. The proposed process is characterised by the fact that at least one of the two antigens has several epitopic regions which react with the antibody to be determined.
