Test information: Transplacental or fetomaternal haemorrhage (FMH) may occur during pregnancy or at delivery and lead to immunisation to the RhD antigen if the mother is RhD negative and the baby RhD positive. Maternal production of an antibody to the RhD antigen is the most important cause of haemolytic disease of the newborn (HDN) in subsequent pregnancies. Samples must conform to the labelling requirements as per Blood Transfusion acceptance criteria.
