What are Platelets?Platelets are blood cells that help control bleeding. When a blood vessel is damaged, platelets collect at the site of the injury and temporarily repair the tear. Platelest then activate substances in plasma which form a clot and allow the wound to heal. What is Apheresis?Apheresis (ay-fur-ee-sis) is a special kind of blood donation that allows a donor to give specific blood components, such as platelets. During the apheresis procedure, all but the needed blood component is returned to the donor. Why is Blood Separated?Different patients need different types of blood components, depending on their illness or injury. After you donate whole blood, the unit is separated into platelets, red cells, and plasma in our laboratory. Only two tablespoons of platelets are collected from a whole blood donation. Six whole blood donations must be separated and pooled to provide a single platelet transfusion. However, one apheresis donation provides enough platelets for one complete transfusion --- that is six times the amount collected from a whole blood donation. Who Needs Platelets?Many lifesaving medical treatments require platelet transfusions. Cancer patients, those receiving organ or bone marrow transplants, victims of traumatic injuries, and patients undergoing open heart surgery require platelet transfusions to survive. Because platelets can be stored for only 5 days, the need for platlet donations is vast and continuous. Platelet transfusions are needed each year by thousands of patients like these:
Who Can be an Apheresis Donor?If you meet the requirements for donating blood, you probably can give platelets. Apheresis donors must:
Are Apheresis Donations Safe?Yes. Each donation is closely supervised throughout the procedure by trained staff. A small percentage of your platelets are collected, so there is no risk of bleeding problems. You body will replace the donated platelets within 72 hours. The donation equipment (needle, tubing and collection bags) are sterile and discarded after every donation. How Does the Procedure Work?Blood is drawn from your arm through sterile tubing into a centrifuge. The centrifuge spins the blood to separate the components. A valve is opened along the spinning tube at the level containing platelets. These platelets are drawn up into a collection bag, while the remaining blood components (red cells and plasma) are returned to you. How Long Does it Take?Depending on your weight and height, the apheresis donation process will take approximately 70 minutes to two hours. You may watch television, listen to music, or simply sit back and relax while helping to save a life.
