Final answer:
Agglutination is a reaction where antibodies interact with antigens on red blood cells, causing them to clump together. It is crucial in blood typing and transfusions, ensuring compatibility between donor and recipient blood types.
Explanation:
Agglutination occurs when antibodies in the blood interact with antigens on red blood cells, causing them to clump together. This reaction is crucial in blood typing and transfusions. In the context of the given scenarios:
- A patient with type O blood receiving type A blood would result in agglutination because the anti-A antibodies in the recipient's blood would react with the A antigens on the donor's blood, causing clumping.
- Similarly, a patient with type AB blood receiving type B blood would lead to agglutination due to the anti-B antibodies in the recipient's blood reacting with the B antigens on the donor's blood.
- On the other hand, a patient with Rh-positive blood receiving Rh-negative blood would not result in agglutination since the Rh-negative blood lacks the Rh antigen that would trigger a reaction in the recipient's Rh-positive blood.
