[Clinical importance of the determination of specific HBsAg and IgM class antibody complexes in acute viral hepatitis B].

In a group of 10 patients with acute viral hepatitis type B in 1985-1988 repeatedly RIA and IRMA estimations of specific signs of infection were made. Concurrently the sera were examined for the presence of a new "marker"--complexes of HBsAg with a class IgM antibody. Detection of these complexes in serum is of diagnostic and prognostic value, in particular when dynamic changes in the course of time are investigated.
