Special equipment is used that can seperate red blood cells, plasma or platelets. The amount of blood taken is replaced. There are no side effects.
The Apheresis Donation Process: Safe and Easy Similar to a whole blood donation, an aphersis donation consists of four steps: registration, health history and mini-physical, donation, and refreshments. From registration to refreshments, the process lasts 1½ -2½ hours. During the actual donation, you will sit in a comfortable recliner, and a carefully monitored machine will draw blood from one arm through sterile tubing into a cell separator centrifuge. The blood stays inside the self-contained sterile tubing and never comes in contact with the machine. After the blood component(s) have been collected, the rest of the blood is returned to the donor through the same arm or the other arm. It’s a safe process — the collection sets and needles are sterile, used once for each donor and then discarded. Donors usually relax, read, or enjoy a movie during the donation.
