The prognostic significance of in-vitro complement fixation (V.C.F.) by hepatitis-B core antigen/antibody immunocomplexes in hepatitis-B surface antigen (HBsAg) positive liver biopsy specimens was prospectively evaluated in 47 patients presenting with acute viral hepatitis type B. 34 of 37 V.C.F.-negative patients made an uneventful recovery and became HBsAg negative; in all patients with a V.C.F.-positive test chronic hepatitis and persistent antigenaemia developed. The V.C.F. test is a simple and reliable prognostic indicator of persistent infection and of progression of apparently acute hepatitis to a chronic liver disorder.
