Questions and Answers
Transfusions transfer blood, or one of the components of blood, from one person to another. For most transfusions it is necessary to match the blood groups of the donor and the recipient, although the use of some blood products, such as clotting factors, may not require matching of blood groups. The mixing of blood types that are incompatible can cause the erythrocytes to clump together, or ______.

Study Notes
Blood Antigens and Antibodies
- A antigen is present on red blood cells of A and AB blood groups, and A antibody is present in plasma of B and O blood groups.
- B antigen is present on red blood cells of B and AB blood groups, and B antibody is present in plasma of A and O blood groups.
- AB blood group has both A and B antigens on red blood cells and neither A nor B antibody in plasma.
- O blood group has neither A nor B antigen on red blood cells and both A and B antibodies in plasma.
Blood Transfusions
- Blood transfusions transfer blood or its components from one person to another.
- Matching blood groups between donor and recipient is necessary to prevent agglutination, except for some blood products like clotting factors.
Agglutination
- Agglutination is the clumping together of erythrocytes due to incompatibility of blood types.
- It occurs when the recipient's blood contains or can produce antibodies against the antigens on the donor's red cells.
Blood Group Matching
- The ABO blood group of the donor must be matched to that of the recipient to prevent agglutination.
- Incompatible blood types can cause the recipient's immune system to react, leading to serious health consequences.
Universal Donor
- Blood group O is considered the universal donor because it has neither A nor B antigen on red blood cells, making it compatible with all ABO blood groups.
Blood Transfusion Importance
- Matching blood groups is crucial to prevent agglutination and ensure safe transfusions.
- Failure to match blood groups can lead to serious health consequences, including death.
Blood Components
- Red cell concentrate is the most commonly transfused part of blood.
- Patients with severe bleeding may receive plasma transfusions to help replace lost blood volume and clotting factors.
