(T-lymphocytes can cause a reaction when transfused, but can also cause what is called “graft-versus-host” problems with repeated exposure to foreign cells.) • “Leukocyte reduced blood” has been filtered to remove the white blood cells which contain antibodies that can cause fevers in the recipient of the transfusion. (These antibodies, with repeated transfusions, may also increa
