. Filtration leukapheresis‐procured leukocytes (FL‐leukocytes), which were collected by the elution of filtration columns with vigorous tapping, released a certain amount of H 2 O 2 , even in the absence of any phagocytic stimuli. Furthermore, FL‐leukocytes, eluted with either gentle or vigorous tapping, exhibited a marked release of H 2 O 2 during phagocytosis. The myeloperoxidase (MPO) activity of FL‐leukocytes was lower than that of leukocytes collected by the dextran sedimentation method (DS‐leukocytes). The data suggest that the release of both H 2 O 2 and MPO from FL‐leukocytes may be related to adverse transfusion reactions and abnormal post‐transfusion kinetics of FL‐leukocytes due to their toxic effects on living cells.
