1. Who can donate?
You can become a volunteer apheresis donor if you meet the following donor health guidelines.
Health: Good
Age: At least 17 years old
Weight: Men and women, minimum of 110 pounds.
Last whole blood donation: At least 56 days (eight weeks) from your last whole blood donation.
Last apheresis donation: At least 48 hours since your last platelet apheresis donation, however, two-week intervals are recommended between each donation.
Donors should not take aspirin or aspirin-containing products for 36 hours prior to donating and cannot have taken any anti-inflammatory medications, such as Nuprin, Advil, etc., for 24 hours prior to donating.
It is a good idea to have donated whole blood in the past before you try your first apheresis donation. That way, you will have an idea of what to expect during the donation process.
2. What happens during the apheresis donation process?
Your blood is made up of several components, including red cells, white cells, plasma and platelets. When you donate a unit of whole blood, you are giving all of these components. A special procedure call "apheresis" provides the means to donate just the platelets in your blood, and then return the remaining components back to you.
3. How does the process work?
Whole blood drawn from your arm enters an instrument called a cell separator. Inside the blood cell separator, platelets are carefully removed by a spinning process. The blood platelets are then collected into a sterile plastic bag, while the remainder of the blood is returned to you.
4. Is the procedure safe?
A platelet donation is as safe and painless as a whole blood donation. All needles and tubing are new, sterile and used only once. There is no direct contact between your blood and the cell separator.
5. How long does the donation take?
The entire process of donating platelets takes about two hours. The procedure is longer than a regular whole blood donation, because it takes more time to separate and collect the platelets from the other components in your blood.
6. Does it hurt?
You will only feel a slight pinch when the needle is placed into the arm.
There are a few side effects which may occur. Some donors feel a slight tingling around their lips and nose when they donate platelets. This is a mild reaction to the blood anticoagulant used during the procedure. The nurse can correct this by adjusting the instrument. Some donors feel a slight chill during donation because the blood is cooler when it is returned. However, because the apheresis procedure removes only the platelets from your blood, possible side effects experienced during whole blood donations (such as lightheadedness) are avoided.
7. How often can you donate platelets?
Your body is able to replenish its supply of platelets very quickly -- usually within 24 hours. Thus, you can donate platelets as frequently as twice a week. However, you cannot donate platelets more than 24 times a year, and you must wait eight weeks following a whole blood donation to give platelets.
