Detailed explanation-1: -Hemolytic disease of the fetus and newborn (HDFN) is also known as alloimmune HDFN or erythroblastosis fetalis. It is caused by the destruction of neonatal red blood cells by maternal immunoglobulin G (IgG) antibodies. The formation of maternal antibodies in response to a fetal antigen is called isoimmunization.

Detailed explanation-2: -Erythroblastosis fetalis destroys red blood cells As a result, the fetus will not receive enough oxygen, which may lead to anemia, other illnesses, or even death. As hemolysis continues, the fetus will rapidly attempt to produce more red blood cells.

Detailed explanation-3: -Erythroblastosis fetalis is hemolytic anemia in the fetus caused by transplacental transmission of maternal antibodies to fetal red blood cells, usually due to incompatibility between maternal and fetal blood groups, often Rho(D) antigens.

Detailed explanation-4: -erythroblastosis fetalis, also called hemolytic disease of the newborn, type of anemia in which the red blood cells (erythrocytes) of a fetus are destroyed in a maternal immune reaction resulting from a blood group incompatibility between the fetus and its mother.

Detailed explanation-5: -This occurs when the mother’s blood type of A, B, or O isn’t compatible with the baby’s. This condition is almost always less harmful or threatening to the baby than Rh incompatibility. However, babies can carry rare antigens that can put them at risk for erythroblastosis fetalis.
