[Liver status in ostensibly healthy carriers of the hepatitis-Bs antigen].

One hundred eighty five ostensibly healthy candidates for blood donors, HBs positive, were examined at the clinic and laboratory as regards liver disturbances. About one fourth of the examined gave either subjective complaints or showed objective changes, deviations in the paraclinic resp. As patients with chronic hepatitis were proved to be 8,11 per cent of the subjects, 28,65 per cent--hepatitis suspected patients and 63,24 per cent were admitted to be healthy antigen-carriers. Urine urobillinogen reaction, thymol test and transaminase are sufficient for the purpose of preliminary screening. About one third of the antigen positive subjects cannot be accurately defined by the routine clinical-laboratory examination and additional immunoserological and immunohistological methods proved to be necessary.
