Immune‐mediated acute or delayed transfusion reactions occur when there is immunological incompatibility between transfused blood products and recipient's antibodies. Acute haemolytic transfusion reactions occur within 24 h and are delayed after 24 h up to 10 days following transfusion, whereas post‐transfusion purpura (PTP) typically occurs 7–10 days post‐transfusion. We present a case of a previously transfused and recently post‐partum female who developed both delayed haemolytic transfusion reaction (DHTR) and PTP.
