Anti-Jk^a was identified in a previously transfused patient. Five cells that were homozygous for Jk^a yielded 2+ reactions in the AHG phase. The same cells were treated with ficin and yielded 3+ reactions in AHG. Therefore, Jk^a is by enzyme treatment.

Question 33

A woman came in for a cesarean section. The antibody screen was positive with a 3+ reaction in the AHG phase using screening cell I. Screening cells II and III were negative in all phases. An 8-cell panel was performed that paralleled the antibody screen, where three cells reacted 3+ at AHG and five cells were negative at all phases of reactivity. The antibody identified was anti-Kell.
