[Detection of hepatitis B antigens by use of the immunoenzymatic method (ELISA)].

The Authors investigated HBs antigen with an immunoenzymatic method (E.L.I.S.A.) in the sera of RIA and I.H. HBsAg positive hepatitis patients, in the sera of RIA and I.H. HBsAg-negative hepatitis patients and in those of normal subjects. E.L.I.S.A. test supplied results almost superposable to those obtained by RIA and therefore it seems worthy to be included among the most reliable techniques to detect hepatitis B surface antigen.
