Study Notes
Blood Types and Antigens
- Blood types are determined by antigens present on the surface of red blood cells (RBCs).
- Antigens A and B are the primary determinants of blood type.
- Blood type A has the A antigen.
- Blood type B has the B antigen.
- Blood type AB has both A and B antigens.
- Blood type O has neither A nor B antigens.
Antibodies and Blood Type Compatibility
- Antibodies, also known as agglutinins, are present in blood plasma.
- Blood type A has anti-B antibodies.
- Blood type B has anti-A antibodies.
- Blood type AB has no antibodies.
- Blood type O has both anti-A and anti-B antibodies.
- Blood transfusions are successful when the recipient's plasma does not contain antibodies against the donor's blood type.
- Hemolysis occurs when RBCs burst due to antibody-antigen reactions during incompatible transfusions.
Universal Blood Types
- Type O blood is considered the universal donor because it lacks both A and B antigens, avoiding reactions with recipient antibodies.
- Type AB blood is the universal recipient because it lacks antibodies, allowing it to receive any blood type without reactions.
Rh Factor
- Blood is also classified as Rh positive or Rh negative based on the presence or absence of the Rh antigen.
- Rh positive blood has the Rh antigen.
- Rh negative blood lacks the Rh antigen.
Rh Incompatibility
-
Rh incompatibility can occur in two scenarios:
- Blood transfusion: When an Rh-negative individual receives Rh-positive blood, antibodies against the Rh antigen develop.
- Pregnancy: An Rh-negative mother carrying an Rh-positive fetus can develop anti-Rh antibodies, potentially harming future pregnancies.
Blood Type Compatibility Summary
-
Type A blood:
- Recipient: A, AB
- Donor: A, O
-
Type B blood:
- Recipient: B, AB
- Donor: B, O
-
Type AB blood:
- Recipient: A, B, AB, O
- Donor: AB, O
-
Type O blood:
- Recipient: O
- Donor: O
