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

In spite of routine screening for HBsAg by a sensitive radioimmunoassay, some cases of posttransfusion hepatitis B still occur. The frequency in the Gothenburg Blood Center is 1 clinical case per 10,000 bloods units transfused. About the same incidence has been noted for clinically overt cases of hepatitis non-A, non-B. In contrast to findings reported by others, the latter incidence has been rather stable over the last 5 years.
