Isoimmunization Is Unlikely to Be the Cause of Hemolysis in ABO-Incompatible but Direct Antiglobulin Test-Negative Neonates. • Provide client and family teaching. Aim: Neonatal blood group B seems to be more predisposing to acute hemolysis and severe hyperbilirubinemia. However, studies supporting IVIg had methodological issues. C. ABO Incompatibility (1) Genetics: With maternal blood types A and B, isoimmunization does not occur because the naturally occurring antibodies (anti-A and -B) are IgM, not IgG. Hemolytic disease develops in approximately 10% of such newborns and may be associated with clinically significant neonatal hyperbilirubinemia2. Here, a case of ABOi HDN clearly met criteria for exchange transfusion. Haemolytic disease of fetus and new-born occurs most commonly in ABO and Rh incompatibility. ABO incompatibility: present in ∼ 20% of all pregnancies; however, only 5–10% of newborns from these pregnancies are symptomatic.

Intensity is generally lower than in RhD allo-immunization. • In addition, initiation of early feeding and exchange blood transfusions may be immediate measures required to reduce indirect bilirubin levels. Hence, ABO incompatibility has now become the single largest cause of HDFN in the western world. BACKGROUND: ABO incompatibility is now the most common cause of isoimmune hemolytic disease of the newborn here. We estimated the risk of ABO HDN with view to determining need for routine screening for ABO incompatibility between mother and fetus. However, at serum bilirubins above 301 μmol/l, ABO incompatibility was a major cause of jaundice in almost 58 per cent of infants. Rh incompatibility can cause very serious HDN, while ABO incompatibility is usually much less severe. Background .
