35,000 pints of blood are needed every day.

The national blood supply must cover every day needs and unexpected disasters. Frequent volunteer blood donors ensure that blood is ready (collected and tested) and available year-round whenever and wherever it is needed.

A common misunderstanding about blood usage is that accident victims are the patients who use the most blood. Actually, people who receive the most blood include those:

  • being treated for cancer
  • undergoing orthopedic surgeries
  • undergoing organ and marrow transplants
  • undergoing cardiovascular surgeries
  • being treated for inherited blood disorders

Every 2 seconds someone in the United States needs blood.


Major disasters do not usually require large amounts of blood, and in most cases hospitals rely on the blood that is already on their shelves to save lives.

But that's when blood centers see the greatest outpouring of support from donors.
Blood is needed everyday. You can help blood centers fill every request for blood by making sure it is available before it's needed.

Included below are charts that breakdown the usage of both red blood cells and platelets with U.S. hospitals.
