Method and apparatus for machine separation of blood and blood components that u tilizes improved administration of anticoagulant to the red cell suspension output. Anticoagulant (20) is added to incoming whole blood (13) in an amount sufficient to prevent clotting of the whole blood in the flow path upstream of the blood co mponent separator (46), but in an amount insufficient to prevent clotting of the red cell suspension created by the separator. Anticoa gulant (20) is added to the red cell suspension downstream (50) of the separator (46) in order to prevent clotting. By adding an additional aliquot of anticoagulant to the red cell suspension, the amount of anticoagulant added to whole blood before separation c an be reduced or eliminated, resulting in an increase in platelet yield during the blood component separation step. |
