Delayed hemolytic reaction means that 7~14 days after blood transfusion, the transfused person develops unexplained hemolytic symptoms, including fever, anemia, jaundice and hemoglobinuria. Symptoms are often not serious, but it can cause systemic inflammatory response syndrome, and in severe cases, cause multi-organ failure, etc., which needs to be taken seriously.
