Fya antibodies were detected in 5 Fy(a-b-) black patients during a 5-year period. The Duffy phenotype was confirmed using anti-Fya, anti-Fyb, and anti-Fy3 by an adsorption-elution technique. These 5 patients had sickle cell disease and had received multiple blood transfusions. The antibodies were all found during the investigation of a hemolytic transfusion reaction or failure to achieve the desired red cell increments after transfusion.
