Antibody Titer, Erythrocytes
Clinical Information: 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.
Useful For: Monitoring antibody levels during pregnancy to help assess the risk of hemolytic disease
of the newborn
Interpretation: 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 ABID2/8988 Antibody Identification, Erythrocytes. A
consultation service is offered, at no charge, regarding the clinical relevance of red cell antibodies.
Reference Values:
Negative
If positive, result will be reported as the reciprocal of the highest dilution at which macroscopic
agglutination (1+) is observed.
