Is ABO blood compatibility enough for the safety of blood transfusion?
Besides ABO blood compatibility the compatibility concerning the Rh blood system must also be checked. In addition it is of fundamental importance for the safety of blood transfusion performing tests to detect agents of main blood transmitted infectious diseases, like HIV (AIDS), hepatitis B and C, syphilis, Chagas disease, etc. (Any transfusion must be studied, planned and supervised by doctors.)
