A mismatch of blood types during a transfusion is dangerous because ________. preformed antibodies in the recipient's blood will
bind and clump (agglutinate) the donated cells antibodies in the donor's plasma will attack and kill the recipient's healthy blood cells white blood cells from the donor's blood cause inflammation clotting factors in the donor's blood will cause unwanted clots known as thrombus
The answer is Preformed
antibodies in the recipient's blood will
bind and clump the donated cells.
Every person’s blood
type is determined by the antigen on their blood cells. If a person is of blood group A, then they have antigen A in their blood cells. Additionally, the same person will have antibodies to the alternative antigen, i.e in our case the
person with blood group A will have
antibodies for antigen B. Therefore if a patient with blood group A is transfused
with blood group B blood, then the antibodies in the patient will bind to the transfused
blood cells and cause agglutination.
