A Woman Came in for a Cesarean Section

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. What procedure might be helpful in predicting the infant's susceptibility to HDN?

A) Determination of the mother's phenotype
B) Determination of the father's phenotype
