-Joa and anti-Jkb. Fortunately, the transfused RBC unit was Jk(b–). Therefore, the crossmatch incompatibility was attributed to anti-Joa, which targets a highprevalence antigen found in 100 percent of most populations. Two weeks after discharge, the patient returned in sickle vasoocclusive pain crisis. The patient was clinically stable, but her Hb was 6.7 g/dL. One unit of Fy(a–), Jk(b–), C–, E–, K–, HbS– RBCs, which was weakly crossmatch-incompatible
