Some maternal IgG alloantibodies to red blood cell antigens will cross the placenta and cause hemolysis of antigen-positive fetal red cells. The resulting fetal anemia and hyperbilirubinemia can be harmful or even fatal to the fetus or the newborn.
Monitoring antibody levels during pregnancy to help assess the risk of hemolytic disease of the newborn
The specificity of the maternal alloantibody will be stated. The titer result is the reciprocal of the highest dilution at which macroscopic agglutination (1+) is observed.
If the antibody problem identified is not relevant in hemolytic disease of the newborn or if titrations are not helpful, the titer will be canceled and will be replaced by ABID2 / Antibody Identification, Erythrocytes.
A consultation service is offered, at no charge, regarding the clinical relevance of red cell antibodies.
Not useful for evaluating the efficacy of Rh-immune globulin after it has been administered
If positive, result will be reported as the reciprocal of the highest dilution at which macroscopic agglutination (1+) is observed.
