How can a body reject a blood transfusion?
A doctor has provided 1 answer
Antibodies: Antibodies are produced by the body to defend against "foreign" substances, such as bacteria, viruses or cells from another person and generally circulate in the blood. If transfused red blood cells have structures on their surface that are different than those on your own red cells, the body may unleash this army of antibodies to attack and kill transfused cells.
