Clinical Information
- A condition 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.
- Hemolytic anemia of the fetus or newborn caused by transplacental transmission of maternally formed antibody, usually secondary to an incompatibility between the blood groups of mother and offspring.
