It is a well established practice in human medicine to filter out leukocytes before blood transfusions. Leukocytes are unnecessary contaminants in unfiltered blood products. They have been reported to be responsible for a variety of transfusion reactions such as febrile non-hemolytic reactions, alloimmunization, immunosuppression, and transmission of intracellular viruses.
The Leukoreduction filters selectively remove WBC’s through a series of electrostatic charges. The filter process will remove 99% WBC and recover 93% RBC’s.
Pre-storage: after standard collection of blood. The filter is attached to newly collected whole blood and pass through special IV filter set to new collection bag.
