Incidence of anti-D at delivery in previously non-immunized Rh-negative mothers with Eritrpblastosis babies. The blood incompatibility is uncovered through blood tests such as the direct Coombs test, which measures the level of maternal antibodies attached to the baby’s red blood cells.

Although the risk of Rh immunization after abortion at 6 to 8 weeks’ gestation is small, it becomes significant by 10 to 12 weeks.

The placenta should not be removed manually to avoid squeezing fetal cells into the maternal circulation.

Antibodies are produced when the body is exposed to eeritroblastosis antigen foreign to the make-up of the body. Red blood cells RBCs from the fetus leak across the placenta and enter the woman’s circulation throughout pregnancy with the greatest transfer occurring at delivery. The epoch-making experiments of Landsteiner and Wiener in revealed the true state of affairs.

The newborn may need urgent medical treatment. Suggestions have been made that women of child-bearing age or young eritrpblastosis should not be given a transfusion with Rhc-positive blood or Kell 1 -positive blood to avoid possible sensitization, but this would strain the resources of blood transfusion services, and it is currently considered uneconomical to screen for these blood groups.

It is rare for a mother to become sensitized during the course of her first Rh-positive pregnancy because the amount of fetal Rh antigen that enters maternal circulation is insufficient to cause sensitization; usually only during labour will exposure be significant. Blood group Rh-D factor in human trophoblast determined by immunofluorescent method. If fetal cells clear quickly after a dose of two vials and if passive anti-D is present, neither Rh immunization of the mother nor getalis of the fetus is likely.

Erythroblastosis Fetalis

ABO incompatibility confers substantial erihroblastosis against the primary Rh immune response; it confers no protection against the secondary Rh immune response. Such infants are better delivered 2 to 3 weeks before term.
