Hemolytic disease of the newborn, also known as hemolytic disease of the fetus and newborn, HDN, HDFN, or erythroblastosis fetalis, is an alloimmune condition that develops in a fetus, when the IgG molecules (one of the five main types of antibodies) produced by the mother pass through the placenta.
The disease process that occurs in the fetus or baby is known as hemolytic disease of the fetus/newborn. It is a direct result of the red cell alloimmunization in the mother. In severe cases the baby develops generalized edema (swelling all over his/her body), also known as hydrops fetalis.
