DONATING PLATELETS
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. Platelets
then activate substances in plasma, which form a clot and
allow the wound to heal.
What is Apheresis?
Apheresis 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 components are 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's 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 platelet donations is vast and continuous.
Platelet transfusions are needed each year by thousands of
patients like these
Heart Surgery Patient, 6 units
Burn Patient, 20 units
Organ Transplant Patient, 30 units
Bone Marrow Transplant Patient, 120 units
Who Can be an Apheresis Donor?
If you meet the requirements for donating blood, you
probably can give platelets. Apheresis donor must:
be at least 17 years of age
Be in good health
Weigh at least 110 pounds
Not have taken aspirin or products containing aspirin
36
hours prior to donation
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. Your body will replace the donated platelets
within 72 hours. The donation equipment (needle, tubing,
collection bags) are sterile and discarded after every
donation, making it virtually impossible to contract a
disease from the process.
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, which vary in weight and density. These
platelets are drawn up into a collection bag, while the
remaining blood components (red cells and
plasma) are
returned to you through your arm.
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 sleep, listen to music, or simply sit back
and relax while helping to save life.
