Abstract
UNDOUBTEDLY the most unsatisfactory situation in blood banking today is the inability to exercise any real control over the hazard of transmitting homologous serum jaundice by whole-blood transfusions. The risk is inherent in every bottle of blood issued. The problems of control are multiple: no donor's history is really reliable; any donor may be an innocent carrier; no laboratory test, or group of tests, is specific for the virus of hepatitis; there is no way of treating the blood to kill the virus without violating essential storage or safety requirements for whole blood; there is no susceptible laboratory test animal . . .
