2.6: Other clinically important blood group systems

Alloantibodies to the Kidd (Jk) system are an important cause of delayed haemolytic transfusion reactions (see Chapter 5). Kell (anti-K) alloantibodies can cause HDFN and it is important to avoid transfusing K positive red cells to K negative girls and women of child-bearing potential. Before red cell transfusion, the plasma of recipients is screened for clinically important red cell alloantibodies so that compatible blood can be selected.
