[Use of the immunoautoradiographic method for determining HBsAg in the blood of serum hepatitis patients].

The use of immunoautoradiography for HBsAg detection increased its primary detection rate in the blood of patients with acute serum hepatitis to 70% (by 12--15% more than in the gel precipitation test). Antigenemia in patients with acute serum hepatitis has been shown to last much longer than could be determined by gel precipitation. As a result of this, over 60% of the patients with HBs-antigenemia in the acute period are discharged from the hospital still containing the antigen.
