Anti-Rh factor antibodies

Definition

Anti-Rh factor antibodies are immune proteins produced in response to the Rh antigen on red blood cells. They play a crucial role in Rh incompatibility, particularly in pregnancy.

5 Must Know Facts For Your Next Test

1. The presence of anti-Rh antibodies can lead to hemolytic disease of the newborn (HDN).
2. Rh-negative individuals can develop these antibodies after exposure to Rh-positive blood.
3. In subsequent pregnancies, these antibodies can cross the placenta and attack the fetal red blood cells if the fetus is Rh-positive.
4. Rho(D) immune globulin (RhoGAM) is used to prevent the formation of anti-Rh antibodies in Rh-negative mothers.
5. The production of anti-Rh antibodies is an example of alloimmunity.
