An immunoassay detecting hepatitis C virus core antigen was evaluated for its ability to predict clinical outcome in a series of patients with acute hepatitis C. In subjects who cleared the virus, core antigen was no longer detectable within 16 weeks of onset, whereas considerable fluctuations were noted among patients progressing to chronic hepatitis, one of whom showed consistently negative values despite the intermittent presence of viral RNA.
