title: [HBAg-RIA as a parameter of functional evaluation of viral hepatitis].
abstract: The investigation of HBAg by RIA appears to be very helpful in the diagnosis and follow-up of viral hepatitis. In most cases, a prolonged antigenemia is more strongly indicative of chronic evolution of the illness than other parameters. The persistence of HBAg, therefore, is significant for the persistence of viral infection.
