Hepatitis B and Non-A, Non-B in a Swedish Blood Center during 10 Years of HBsAg Screening

Abstract
In spite of routine screening for HBsAg [hepatitis B surface antigen] by a sensitive radioimmunoassay, some cases of posttransfusion hepatitis B still occur. The frequency in the Gothenburg Blood Center is 1 clinical case/10,000 blood units transfused. About the same incidence was noted for clinically overt cases of hepatitis non-A, non-B. In contrast to findings reported by others, the latter incidence was rather stable over the last 5 yr.
