See Cytapheresis, Hemapheresis, Plateletpheresis.
Leukapheresis types  
'Harvesting' leukapheresis WBCs are donated from healthy subjects to immunocompromised and leukopenic Pts, which may be effective in short-term therapy of acute infections; long-term, Pts become either immunized against the donor antigens or infected with pathogens; 1010 granulocytes are needed for adequate 'coverage' against infections; to maximize the harvest, the donor receives corticosteroids
Reduction leukapheresis WBCs that compromise normal circulation are removed to temporarily relieve Sx of hyperleukemia–> 100 x 109/L; in a typical procedure, ± 6 liters of whole blood are processed to remove 5-10 x 109 WBCs

leuk·a·phe·re·sis
