title: [Behavior of HBs Ag and HBs Ab in chronic hepatitis].
abstract: The preliminary results of the HB, Ag and HBs Ab assay, performed with radioimmunological techniques in 31 cases of chronic hepatitis, 13 of whom carriers of chronic aggressive hepatitis (C.A.H.), 9 of chronic persistent hepatitis (C.P.H.) and 9 of cryptogenetic hepatic cirrhosis (C.H.C.) of both sexes, are reported. The highest number of HBs Ag positive cases was observed both in C.A.H. (69%) and C.H.C. (55%); very lower the HBs Ag positivity both in C.A.H. (33%) and C.H.C. (33%). No correlation between HBs Ag positive and HBs Ab positive was observed.
