Specializes in Pathology

Immunologic: Causes for transfusion allergic reactions are immune related and depending on the severity can be mild (hives, urticaria, rash) to severe anaphylaxis and shock(hypotension, respiratory obstruction) These can be from allergens present in the transfused unit or substances like cytokines in the blood product that may activate the recipient's immunologic system.
