Platelet Donation

BY Nancy Janiola IN , 2 comments

Blood is a mixture of red cells, white cells, plasma, platelets and more. Plateletpheresis is  special blood donation process that allows you to give just one part of your blood - platelets - the cells that help stop bleeding. There's an excess supply of platelets in the blood and much of them can be given away with no ill effect.

Until recently, the only way to collect enough platelets for a single transfusion was to take units of blood given by five to 10 donors, separate the platelets from the other blood cells using a centrifuge and combine the platelets.

Today, sophisticated medical equipment - blood separators can collect enough platelets for transfusion from a single donor. Blood that's drawn from your arms goes into the blood cell separator instead of going into a plastic bag, as it would in a regular blood donation. When the blood is in the separator the platelets are carefully removed. The rest of your blood - the plasma, red cells and white cells - is returned to you through the other arm. It's a simple, safe process.

Who can give platelets?

The same good health requirements that govern whole blood donors apply. Requirements do vary, so check with your blood center.

How long does it take?

Plateletpheresis takes one to two hours to complete. The procedure is longer than a regular donation because it takes extra time to separate and collect the platelets from the other blood components.

How often can I give platelets?

Your body is able to replenish its supply of platelets very quickly so they are always in plentiful supply. Generally, a person may donate platelets as frequently as every 48 hours but not more than 24 times a year. Restrictions vary, however.

Are there any side effects?

Because plateletpheresis takes out only platelets and returns the other blood components to your body, many of the side effects some people have when they give whole blood are avoided. Some donors feel a slight tingling sensation around their lips and nose when they donate platelets. This is a mild reaction to the blood anticoagulant used in the procedure and can be stopped. You also might feel a slight chill during donation and may need a blanket.

Why should I be a plateletpheresis donor?

Donations of platelets help people with very special health care needs. These people may be undergoing serious health problems like leukemia, cancer and aplastic anemia. The transfusion can mean the difference between life and death. So you can be sure that your platelet donation is helping save a life.

Donating Blood is a Lifesaving Act

BY Nancy Janiola IN , No comments

A healthy Filipino has 16 - 18 glasses of blood. Donating 250 - 450 cc. (approximately 1 glass) will not cause any weakness or ill effects.

Giving blood will not take up too much of your time - the whole process just takes 30 minutes.

Advantages of Giving Blood

  • When a person donates blood, his bone marrow is stimulated to produce new red blood cells and make his blood-forming organs function more effectively. The young cells generated will mean more effective and active cells. In the same way that a car works better after a "change oil", donating blood will make a person feel better. A healthy person can donate blood every three (3) months with no ill effects.

  • A Red Cross donor is given a Blood Donor Card. With this card, the donor will be given priority based on stock availability, in case of blood needs. The blood Donor Card is transferable to family members and friends and has no expiration date.

  • Prospective donors who submit themselves to the procedure will be examine by a physician for free. Donors will also know their blood type and know whether they are anemic of not.  Donors will be informed of diseases seen in the blood as the result of the screening tests.


General and Physical Requirements of a Blood Donor

Age. Persons 18 - 60 years old can donate blood. Regular donors can give blood until they are 65 years old. Those aged 16 - 17 may also give blood, with parent's or guardian's consent.

Sex. Both men and women are accepted as donors.

Weight. Must be at least 50 kgs. (110 lbs.)

Temperature. Oral temperature must not exceed 37.5 Degree Celcius.

Pulse. Must be regular between 48 and 100 per minute.

Blood Pressure. Must be between 110 and 200 mm.Hg systolic and 110 mm.Hg diastolic.

Hemoglobin. The level must not be less than 125 gms./100ml.
