Fetal erythrocytosis, also known as neonatal hemolytic disease, in which the type of anemia of fetal red blood cells (red blood cells) is destroyed by the maternal immune reaction caused by the blood type incompatibility between the fetus and its mother. This incompatibility occurs when the fetus inherits blood factors from the mother's father. The symptoms of embryonic erythroblastosis range from mild to severe, sometimes leading to the death of the fetus or newborn. The two blood group systems Rh and ABO are mainly associated with embryonic erythrocytosis. The Rh system is the cause of the most serious form of disease that can occur when Rh negative women (women with blood cells lacking Rh factor) constitute Rh positive fetuses. When fetal red blood cells with Rh factor (in this case, antigen) pass through the placental barrier and enter the mother's blood, the susceptibility of the mother to the immune system increases.

The severity of fetal erythrocytosis varies with the degree of hemolysis. Symptoms include anemia, the presence of many immature erythrocytes (erythrocytes) in the circulation, jaundice caused by accumulation of bilirubin (degradation products of erythrocyte hemoglobin), hypertrophy of the liver and spleen. In its mild form, the disease only manifests as mild anemia without other complications, in the most extreme form the fetus dies in the uterus. Fetal edema characterized by extreme edema (abnormal accumulation of serum) and congestive heart failure is the most serious form of disease in neonates. Normally, the baby's Rh-positive blood is successfully exchanged with Rh-negative blood Unless the transfusion is exchanged, the baby will die. The complication of fetal erythrocytosis is nuclear jaundice, which is caused by the deposition of bilirubin in the brain. It may cause hearing impairment, mental retardation, or death.

Newborn hemolytic disease is also known as fetal and neonatal hemolytic disease, HDN, HDFN, or embryonic hyperthyroidism. One of the major types of antibodies is produced by the mothers through the placenta. Among these antibodies, some antibodies attack antigens on erythrocytes in the fetal circulation, destroying and destroying cells (hemolysis). Fetuses may develop mesotheliosis and anemia. This fetal disease can cause fetal death (fetal edema) due to heart failure in a range from mild to very severe. If the disease is moderate or severe, many forms of red blood cells (immature erythrocytes) are present in the fetal blood, so these forms of disease may be called fetal erythrocytosis (or erythroblastosis).
