Overall, they are estimated to complicate up to 3% of all transfusions. The incidence of allergic transfusion reactions is associated with the Such reactions may occur in up to 1 in 200 transfusions of RBCs and 1 in 30 transfusions of platelets. Febrile Reactions.

Other symptoms, such as facial flushing, dyspnea, or abdominal cramps may occur but usually hypotension is the sole manifestation. Transfusion Reactions. Hemolytic Reactions.
Delayed immune-mediated transfusion reactions occur within days to weeks of transfusion and include delayed haemolytic transfusion reaction, graft-versus-host disease, and post-transfusion purpura. Allergic reactions occur when patients have antibodies that react with proteins in transfused blood components. Anaphylaxis occurs where an individual has previously been sensitised to an allergen present in the blood and, on re-exposure, releases immunoglobulin E (IgE) or IgG antibodies. 2. Common causes of an acute transfusion reactions include febrile non-haemolytic transfusion reactions and allergy T/F 3.
