Clumping of RBC may occur when blood of one person is mixed with serum or blood of another person. This is due to

  1. Antigen-antibody reaction

  2. Antitoxin-antibody reaction

  3. Antigen-antigen reaction

  4. Antibody-antibody reaction

Show answer
Correct Option: A
Explanation:

The RBC membrane contains either antigen A or antigen B, or both Antigen A and B or no antigen at all, accordingly the blood is classified as blood group A , B , AB and O respectively. The blood plasma of blood group A will have antibodies for B, that of B will have antibodies for A,  that of AB will have non, while that of O will have both the antibodies. If blood is transfused at random this will lead to antigen-antibody reaction - like if A is the blood group of the recipient while the blood group of the donor happens to be B, this will lead to clumping of the RBCs.

So, the correct answer is 'Antigen-antibody reaction'

Anti-A and Anti-B antibodies are not found in which of the following blood group?

bio-chemistry immunity and blood groups blood group blood groups and compatibility advance blood groups and transfusion compatibility of blood groups

  1. AB

  2. A

  3. O

  4. B

Show answer
Correct Option: A
Explanation:

The cell membrane of RBCs in AB blood group contain both antigen A as well as antigen B therefore the blood plasma does not contain antibody A and Antibody B, to prevent the coagulation of blood cells due to antigen-antibody reactions.

So, the correct answer is 'AB'
