Abstract: In the method, either no anticoagulant solution, or an aliquot of anticoagulant solution is added to whole blood upstream of a separator. Anticoagulant solution is added to a separated component downstream of the separator.

Abstract: Method and apparatus are provided for machine separation of blood into blood components, wherein a preselected fluid such as anticoagulant is added to at least two different locations (16, 112) through the fluid flow path of the sec (10), in order to promote the different functional characteristics in different blood components. The method results in reduced incidence of citrate reaction in the blood donor and increased platelet yield in platelet rich plasma (60) collected during the procedure.

Abstract: A method of wetting a plasmapheresis filter with anticoagulant in a plasmapheresis system having a venepuncture needle, a plasma separation device connected in series by a fluid conduit, including operating the system such that an initial limited volume charge of anticoagulant is introduced into the conduit (for wetting the filter of the separation device) in advance of whole blood flowing from the donor towards to the separation device (and pushing the anticoagulant charge ahead of the whole blood into the separation device).
