6. Ravi met with an accident and he needed blood transfusion. In the
blood test it was found that he had antigen A,D and Antibody b in
a) Identify Ravi's blood group.

b) Everyone cannot receive blood from all blood groups. Why?​

Answer 1

Answer:

a) A

b) Plasma compatibility

Patients should only receive plasma that does not contain an antibody which could attack the antigens present on their own red cells. Group A recipients have A antigen on their red cells, so they can't receive group O or group B plasma as the anti-A will attack their red cells.

That means people with type A blood create antibodies against B antigens. A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them
