In an apheresis (ay-fur-ee-sis) donation, from the Greek "to take away," donors give only select blood components — platelets, plasma, red cells, infection-fighting white cells called granulocytes, or a combination of these, depending on the donors' blood type and the needs of the community. Apheresis is most commonly used to collect platelets and plasma.

Patient Benefits
A single apheresis donation of platelets can provide as many platelets as 5 whole blood donations. In addition, a platelet transfusion from a single donor greatly reduces the chances of an immune system reaction to the transfusion. Bone marrow transplant, cancer and leukemia patients whose immune systems are already compromised, benefit particularly from single donor platelet transfusions.

Apheresis donors' donations go through additional typing called Human Leukocyte Antigen (HLA) typing to ensure that the match between donor and recipient is as close as possible. Donors are then matched with specific patients in hospitals. Apheresis donors may receive emergency requests to donate for a patient to whom they are matched. Many apheresis donors find the knowledge that they are helping a specific individual in need particularly rewarding.

People who donate just platelets can donate every 3 days for a maximum of 24 times a year.

Who Can Be an Apheresis Donor?
The same good health requirements that govern whole blood donors apply to apheresis donors. You must be at least 17 years old, weigh at least 110 pounds and be in good health.

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.
