leukoreduction

(loo″kō-rē-dŭk′shŭn) [Gr. leukos, white, + L. reductio, leading back] The loss of white blood cells from a unit of packed red cells by filtration of the blood before transfusion. White blood cells in red cell transfusions have been associated with immunosuppression in recipients. Leukoreduction typically lowers the white cell content of packed red cells from about 3 × 10⁹ per unit of blood to about 2.5 × 10⁵ per unit. It has been associated with a decrease in post-transfusion fevers, and, in some studies, with decreased post-transfusion mortality.
