Abstract
A review is given on post-transfusion hepatitis—the most widespread and clinically important type of iatrogenic hepatitis. The diagnostic criteria, the epidemiology and the prognosis of post-transfusion hepatitis are discussed. Prophylactic measures are reviewed in details. Biochemical and serological tests on donor blood, including tests for Australia antigen, seem of limited prophylactic value. Strict adherence to transfusion blood derived from a stable and persistently donating group of voluntary donors is probably the most important prophylactic measure at present.
