Test of Antigen Fyb
Both Duffy antigens are fully developed at birth. Fya frequently causes immunization while Fyb is rarely the cause of immunization. Anti-Fya and anti-Fyb are practically always of immune origin. They both cause hemolytic transfusion reactions and can, although not frequently, cause hemolytic disease of the new-born (HDN).
