Platelets are yellow in color and the clotting agents in our blood. When we are cut, platelets are essential to help minimize bleeding. Patients being treated for blood diseases, including cancer, often need frequent platelet transfusions as treatment for the disease can reduce platelet count.

A Platelet Donation

Depending on the donor, platelets can be given in a single, double or triple unit. Platelets also are rich with plasma which works closely with platelets to stop bleeding.

A Platelet Donation Is The Ideal Donation For:
  • A Positive
  • A Negative
  • B Positive
  • B Negative

How Often Can I Donate Platelets?

You can donate platelets every 7 days, up to 24 times per year.

Why Donate Platelets?

Platelets must be transfused within 5-7 days of collection. Since they must be used so quickly, and because many patients regularly require this blood component, the need is constant.
