For the simultaneous determination of an antigen of a pathogen and at least one antibody against the same pathogen according to the principle of a heterogeneous immunoassay, the sample with the receptors R1 to R4, where R1 and R3 are specifically bindable with the antigen to be determined, R2 and R4 with the determining antibodies are specifically bindable, R1 and R2 mediate the binding to the solid phase and R3 and R4 carry the same label, incubated and after separation of the solid from the liquid phase the label in one of the two phases is determined. |
