At Canadian Blood Services plasma can be collected by apheresis (Plasmapheresis) or prepared from a whole blood collection (recovered plasma).
Apheresis is the process whereby blood is separated into components during the collection procedure (using a machine specialized for this purpose), allowing only a specific part to be removed. The components not used are returned to the donor.
When the component collected is plasma, the process is referred to as Plasmapheresis.
Each plasmapheresis collection allows Canadian Blood Services to collect 2-3x the amount of plasma that we can collect with a whole blood donation.
Plasma prepared from whole blood donation is separated from the other parts of the blood in the laboratory after the donation.
