Question

Quizplus · Accepted Answer

When a person is transfused with the wrong blood type, the immune system recognizes the foreign antigens on the erythrocytes (red blood cells) of the transfused blood as non-self and mounts an immune response against them. This leads to the agglutination (clumping) of erythrocytes, which can cause serious complications.
