APHERESIS UNIT -
Noun: An apheresis unit is a machine for removing unwanted substances from the blood. Blood is withdrawn from the person in the same way as for a blood donation, and the blood is passed through a cell separator that removes the plasma (the fluid portion, which contains the antibodies ). The formed elements (blood cells) are reconstituted with a plasma substitute or with donated plasma. The reconstituted blood is then returned to the body as in a blood transfusion . This is a rapid procedure designed to quickly control symptoms. This same procedure is used to remove platelets from platelet donors' blood.

Greek - aphaíresis = a taking away
