What are Platelets? - Irish Blood Transfusion Service

What are Platelets?

Call 01 432 2833 (Dublin) or 021 480 7429 (Cork) to speak to one of our staff about giving platelets.

Blood is made in the bone marrow. It is composed of red cells, platelets, plasma and white cells, collectively referred to as blood components. Platelets are essential to enable blood to clot properly.  Patients who do not have enough platelets in their blood are at risk of spontaneous bleeding.

Platelets have a shelf-life of just 5-7 days after donation, so it is important to maintain a constant supply for all Irish hospitals.

Why we need your life saving platelets?

Ireland needs more platelet donors

Platelets are a component of blood, essential to stop bruising and bleeding. Over 22,000 platelet transfusions are needed every year in Ireland. We need every blood group every single day. Many of Irelands patients rely on platelets, so it is important supplies are constantly replenished.

We are always looking for people to become platelet donors.

Who needs your life saving platelets?

Platelets are needed every day for the treatment of patients with cancer, leukaemia, premature babies, major surgery, burns patients, accident victims who have had extensive injury and new born babies.

However, platelets have the shortest shelf life of all blood components, lasting only 5 to 7 days. This means we have a constant need for platelet donors to ensure we meet the needs of these patients. To find out if you are able to donate platelets take our eligibility quiz
