The first example of a Raddon‐like antibody as a cause of a transfusion reaction

Abstract
A serum Raddon defining a low-frequency red blood cell antigen FR, and its association with the Miltenberger antigen complex, were reported in 1977. An antibody of the same serological specificity was the cause of a transfusion reaction. The patient''s reaction and serological response, as well as Raddon frequency and inheritance, are described.
