Study Notes
ABO Blood Group System
- This blood group system is essential for blood transfusions.
- Individuals naturally have antibodies in their serum that target antigens absent from their red blood cells (RBCs). This occurs without prior exposure to RBCs via transfusion or pregnancy.
- These antibodies are called naturally occurring due to their formation without prior contact with RBCs.
ABO Antibodies
- ABO antibodies are primarily of the IgM type.
Rh Antibodies
- Rh antibodies are typically produced after exposure to foreign RBCs, typically through transfusion or pregnancy.
- Rh antigens are highly immunogenic, with the D antigen being the most potent.
- Rh antibodies primarily belong to the IgG class, enabling them to cross the placenta.
- Because Rh antigens develop early in fetal life, Rh antibodies produced by Rh-negative pregnant women can cross the placenta and bind to fetal RBCs that express the Rh antigen.
