How soon can you donate platelets after donating blood

Is platelet donation a safe procedure?

Yes, it is very safe. A full blood count is taken before each donation to ensure that you have enough platelets to donate. Your body replaces all of the platelets that you have given within a few days. It is impossible to catch any viral infection by donating platelets or blood. We use a new sterile disposable set for each donation.

How will I feel after my donation?

After the donation is completed you are asked to take a short rest and have something to eat or drink.  You are then fit to resume normal activities.

How often can I give platelets?

As you keep your red cells during the donation process, it is possible to give platelets every 28 days.  As the demand for platelets is constant we normally ask that you try to donate every four to six weeks.

Where can I donate platelets?

Platelet donations take place at the National Blood Centre, James’s Street, Dublin 8 and the Munster Regional Transfusion Centre, St. Finbarr’s Hospital, Cork. 

Can I continue to give blood?

Not everyone is suitable to be a platelet donor.  So if you have attended for your assessment and you are suitable, we would ask that you just give platelets, for as long as this is possible for you.  If you find that giving platelets is no longer possible for you, you may return to giving blood at any point. 

Why can women who have had pregnancies not donate platelets?

During pregnancy small amounts of blood from the baby can cross over into the mother's blood stream. This is especially likely to happen during the delivery. When this happens the mother's immune system sometimes reacts to the baby's blood cells. As part of this, the mother may develop antibodies to some of those cells. If the mother is a platelet donor, on very rare occasions these antibodies can react with the blood cells of patients who receive her platelet donations. Those reactions can be life threatening so to avoid this risk, the IBTS no longer recruits women who have had a pregnancy of any gestation.

Why can people who have had a blood transfusion not donate platelets?

People who have received a blood transfusion in the past sometimes develop antibodies to the blood cells in the donor's blood. If the person who has received a blood transfusion is a platelet donor, the antibodies in their own blood can, in very rare circumstances, cause serious reactions in the person who receives their platelet transfusion. To avoid the risk of this rare event, the IBTS does not recruit as platelet donors people who have had a blood transfusion in the past.

How do I become a platelet donor?

In order to become a platelet donor you must first attend for an assessment interview.  This simple process includes a blood sample to ensure your own platelet count is suitable for this type of donation.  If you would like to schedule an assessment appointment just fill in our Online Application Form or call 01 432 2833 (Dublin) or 021 480 7429 (Cork) for more information.

How soon can you donate platelets after donating blood

During a platelet donation, blood is drawn into a centrifuge to separate the components. Once separated, the platelets are removed from the centrifuge while the remaining blood components are returned to the donor. The preferred blood types for this procedure are A+, B+, O+, AB+ and AB-, but you can also donate if you are one of the remaining types.

Platelet need

We need platelets EVERY day, but because platelets only have a 7 day shelf life, FRIDAY-MONDAY are higher need days. Collecting more on those days ensures platelets will be ready Monday-Thursday, days when transfusion and surgeries are more likely to be scheduled by a hospital.

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 or videotapes, listen to music, or simply sit back and relax while helping to save a life.

Donor Informed Consent  Donor Informed Consent (Spanish)

preferred blood types

  • A positive
  • B positive
  • O positive
  • AB positive and negative

In addition to the standard donor eligibility requirements, platelet donors have additional medication considerations:

  • No aspirin or aspirin products can be taken 48 hours before donating, because aspirin affects platelets' ability to function properly.
     
  • Some other medications affect platelets and may result in a temporary inability to donate. Piroxicam (Feldene) use requires a 2-day deferral after stopping. The anti-platelet drugs clopidogrel (Plavix), ticlopidine (Ticlid), cilostazol (Pletal), and Aggrenox (dipyridamole) require a 14-day deferral after stopping.  Brilinta (ticagrelor) requires a 7-day deferral after stopping.  Effient (Prasugrel) requires a 3-day deferral after stopping.  
     
  • Ibuprofen Motrin, Advil and many other non-aspirin drugs ARE acceptable.

To be certain a medication is acceptable, call 800-747-5401 and ask to speak to someone in Donor Services Auditing. Donors must never stop prescribed drugs in order to donate, unless they have cleared this with their doctor.
 

Platelet Donation Frequency

Our bodies are constantly replacing platelets so you are eligible to donate once a week, up to 24 times a year. Healthy individuals have a surplus of platelets, so removal of this quantity has no adverse affects.

While donors are eligible to donate more frequently with platelet donations, you don’t necessarily need to commit to giving this often. Our recruitment department is happy to work with you to find a donation frequency pattern that works best for you and fits what time you have to donate. 

  • Wait 7 days after a platelet donation to give whole blood.
  • Wait 7 days after a whole blood or plasma product donation to donate platelets.
  • Wait 28 days after a plasma product donation to donate whole blood.
  • Wait 112 days after a double red cell donation.
