Red Blood Cells Red blood cells RBCs also known as packed red blood cells pRBCs are prepared from whole blood by removing plasma.Patients who benefit most from the transfusion of RBCs include those with chronic anemia resulting from kidney failure or gastrointestinal bleeding and those with acute blood loss resulting from surgery or trauma.
Aug 12 2015 Currently leukoreduction of red blood cells is routine in most developed countries except the United States where only approximately half of RBC units transfused are leukoreduced It has been estimated that the cost of leukoreduction is approximately 35 US dollars per unit of blood product Gorgas and Kaide 2013 .
