Transfusion-associated graft versus host disease primary prevention

Prevention includes gamma irradiation of the lymphocyte-containing blood products. This procedure should be performed in transfusions when:

• the recipient is immunocompromised
• the blood components are from a family donor
• HLA-matched platelets are transferred.

Another means of prevention is the use of third- or fourth-generation leukoreduction filters, although the efficacy of this procedure has not yet been documented.
