About Blood Donations

  • One donation can help multiple patients. Following collection, red blood cells, plasma and platelets are separated, stored and distributed separately.

  • Blood cannot be manufactured – it can only come from generous donors.

  • Blood is composed of 3 main components: red cells, plasma and platelets.

  • Most donated red blood cells must be used within 42 days of collection.

  • Apheresis is a mode of collection that allows a donor to give only the specific blood component that is in need by patients, such as platelets.

  • Platelets are especially in need by cancer patients and must be used within 5 days of collection. New donations are continuously in need.
