Abbreviation: pRBC
A collection of red blood cells that have been prepared for blood transfusion by removing plasma from whole blood. Packed red blood cells may be further treated with leukoreduction to remove leukocytes (reducing the risk of non-hemolytic febrile transfusion reactions) and irradiation to inactivate lymphocytes for use in patients who are immunosuppressed (reducing the risk of graft-versus-host disease).
