title: [Incidence of the Australia antigen in the blood donors of Siena (transfusion centre) (author's transl)].
abstract: 10363 sera from healthy adults, volunteer blood donors (18-65 year aged) have been tested for detection of HBsAg. The frequency of Australia antigen was found to be 0,88% in all sera; 1,01% in male and 0,24% in female donors. The frequency in volunteer blood donors of both sexes has been in the first half of the life (18-40) of 1,07% and in the second half (41-65) of 0,58%.
