The process of blood transfusion is essentially a kind of transplantation. Since it is transplantation, it is bound to be accompanied by a series of possible immune responses. Transfusion-associated graft versus host disease is the most important one. Lymphocytes that are immunologically active in the body of the donor migrate and proliferate in the body of the patient, which in turn attacks the immune system of the patient and has an impact on the stomach, intestines, liver and hematopoietic system of the patient. If liver function is damaged seriously, disgusting, diarrhoea, serious can cause death even. The closer the blood relationship, the higher the incidence rate, especially among the first degree relatives, that is, parents and children, the incidence rate is higher, so in the clinical use of close relatives of blood transfusion has not been very much.
