Due to several advances in modern medicine, HDFN due to anti-D is preventable by treating the mother during pregnancy and soon after delivery with an injection of anti-Rh o (D) immune ...
A Rhc negative mother can become sensitised by red blood cell (RBC) Rhc antigens by her first pregnancy with a Rhc positive fetus. The mother can make IgG anti-Rhc antibodies, which are able to pass through the placenta and enter the fetal circulation. If the fetus is Rhc positive alloimmune hemolysis can occur leading to HDN.
In those with positive tests, follow up testing at a postpartum check should be done to rule out the possibility of a false positive. This could be caused by a hemoglobinopathy in the mother which causes persistent elevation of fetal hemoglobin, e.g. sickle cell trait .

Mothers who are negative for the Kell 1 antigen develop antibodies after being exposed to red blood cells that are positive for Kell 1.Over half of the cases of hemolytic disease of the newborn owing the anti-Kell antibodies are caused by multiple blood transfusions, with the remainder due to a previous pregnancy with a Kell 1 positive baby.

The gene encoding this protein is found on chromosome 18. [3] Three Jk alleles are Jk (a), Jk (b)and Jk3. Jk (a) was discovered by Allen et al. in 1951 and is named after a patient (Mrs Kidd delivered a baby with a haemolytic disease of the newborn associated with an antibody directed against a new antigen Jk (a).
