It is not known if any of these cases were caused by NAIT.
Three women gave birth before the antibody result was available. Four women had spontaneous delivery before elective Caesarean section. Four women chose vaginal delivery because anti–HPA 1a had only been found in 1 sample early in pregnancy. One woman moved to another health region that had not adopted the screening program.
