Question

Blood agglutination tests are used in

• A. Antigen antibody reaction
• B. Animal relations
  
• C. Immunity
  
• D. None of the above

Answer 1

The correct option is A Antigen antibody reaction

Blood agglutination tests are used in Antigen-antibody reactions. The clumping of particles is called as agglutination. Clumping occurs when an antigen is mixed with its corresponding antibody. When people are given blood transfusions of the wrong blood group, the antibodies react with the incorrectly transfused blood group and as a result, the erythrocytes clump up and stick together causing them to agglutinate

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