HDN is characterized by the abnormal presence of ERYTHROBLASTS in the circulation of the FETUS or NEWBORNS. It is a disorder due to BLOOD GROUP INCOMPATIBILITY, such as the maternal alloimmunization by fetal antigen RH FACTORS leading to HEMOLYSIS of ERYTHROCYTES, hemolytic anemia (ANEMIA, HEMOLYTIC), general edema (HYDROPS FETALIS), and SEVERE JAUNDICE IN NEWBORN." Whereas,an immune complex disease is caused by the deposition of antigen-antibody or antigen-antibody-complement complexes on the surface of cells.
So I don't think it's an immune complex disease.

No, Haemolytic Disease of the Newborn(HDN) is not an Immune Complex Disease.It is linked to the presence of Rheshus (Rh) fatcor in the blood of the parents.A Rh negative mother and a Rh positive father will have high chances of giving birth to a child with HDN.This condition only occurs where there is incompatibility between the maternal and foetal blood.
