Patient's Query
Hello doctor,
How long the effect of anti-D and abortion last in the body?
Hello,
Welcome to icliniq.com.
The effect of anti D will last forever until there is another exposure in Rh -ve woman of an Rh +ve blood in the form of blood transfusion or Rh +ve pregnancy. Usually, first pregnancy is spared as the Rh +ve cells when entering the maternal blood at the time of feto-maternal hemorrhage like during labor, or rupture of membranes or abortion, there is sensitization of cells and no harm. But when again in second pregnancy there is a transfer of cells, there is Ag- Ab (antigen-antibody) reaction and hemolysis, means the breakdown of red cells and harm to the fetus in the form of anemia, hydrops, etc. That is why we give an injection of anti D to prevent the sensitization of these cells.
