Question
Hemolytic disease of the newborn (HDN) due to RhD incompatibility depends upon the ....Question 3Select one:a.Transplacental passage of macrophages carrying RhD antigensb.Transplacental passage of anti-RhD antibodiesc.Production of cytotoxic antibodies by the babyd.Inabiity of the baby to react against the mother's red cellse.Mother possessing RhD antigens not present on the baby's red cells
Solution
The correct answer is:
b. Transplacental passage of anti-RhD antibodies
Hemolytic disease of the newborn (HDN) due to RhD incompatibility occurs when a mother who is RhD negative carries a baby who is RhD positive. The mother's immune system can produce anti-RhD antibodies which can cross the placenta and attack the red blood cells of the baby, leading to hemolysis. This is why the transplacental passage of anti-RhD antibodies is crucial for the disease to occur.
