A special kind of blood donation
Apheresis is a special kind of blood donation when specific components — platelets, plasma, or white blood cells — can be collected.
During an apheresis donation, we collect whole blood from the donor and put it into a machine called a "cell separator." We spin the blood in the machine to separate the components and collect a measured amount of the desired component in a special bag. We then return the red cells and other components to the donor.
An apheresis platelet donation can provide as many platelets as six whole blood donations. Also, 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.

Blood is a mixture of red cells, white cells, plasma, and platelets. Platelets are cells that help control bleeding.
Many lifesaving medical treatments require platelet transfusions. Cancer patients, those receiving organ or marrow transplants, victims of traumatic injuries, and patients undergoing open-heart surgery require platelet transfusion to survive.
Depending on your weight and height, the actual apheresis donations process will take approximately 70 minutes to two hours. This includes the donor registration, health interview, and time for refreshments. You may watch television, watch DVDs, listen to music, or just sit and relax while helping save lives.
Platelet apheresis donors need to meet the requirements for donating blood. You must weigh at least 115 pounds, be at least 16 years old with a signed parental consent form and be in good health.
If you meet the requirements to donate blood, your platelet count will be determined during the mini-physical before donation. To be eligible to donate platelets, you cannot have ingested aspirin 36 hours before donation.
Yes, apheresis donations are very safe. Each donation is closely supervised by trained staff who observe the donors throughout the process. Only a small percentage of your platelets are collected, so there are no risks of bleeding. Your body will replace the donated platelets within 48 hours. The donation equipment—needle, tubing, and collection bags—is sterile and discarded after each donation, making it virtually impossible to contract a disease from the process.
The vast majority of apheresis donors experience no discomfort during the collection process. Some feel a slight tingling sensation around the lips and nose during donation. This reaction is caused by the anticoagulant used in the procedure. This can be easily controlled if the donor tells the staff about his or her discomfort. Donors may feel a slight chill during the donation. We'll be happy to provide a blanket to keep you warm.
