During blood transfusion, agglutination could be prevented if a patient having blood group O is given blood
from group
Answer Details
During blood transfusion, agglutination can occur if the donor blood group is not compatible with the recipient's blood group. This happens because of the presence of antigens on the surface of red blood cells that can trigger an immune response. Blood group O is considered the universal donor because it lacks the antigens A and B, which means it can be given to individuals with any blood group without causing an immune response. However, a patient with blood group O can only receive blood from a donor with blood group O, as they have antibodies against both antigens A and B, and receiving blood from other groups can cause an immune reaction and agglutination. Therefore, to prevent agglutination, a patient with blood group O should only receive blood from a donor with blood group O.
