Why Donate Blood?

Every two seconds, someone in the United States needs blood.  That adds up to 44,000 units of blood needed each day.  There is no substitute for human blood - it cannot be manufactured. In the populous Los Angeles region, blood is always in high demand though less than two percent of the population donates. With just one donation, you can help save multiple lives.

Quick facts about blood needs and its supply from the American Red Cross:


  • The average red blood cell transfusion is approximately three pints.
  • A single car accident victim can require as many as 100 pints of blood.
  • More than 1 million new people are diagnosed with cancer each year. Many of them will need blood, sometimes daily, during chemotherapy.
  • Sickle cell disease affects more than 80,000 people in the U.S. Sickle cell patients can require frequent blood transfusions throughout their lives.
  • A total of 30 million blood components are transfused each year in the U.S.
  • More than 38,000 blood donations are needed every day.
  • Less than 38 percent of the U.S. population is eligible to give blood.
  • Type O-negative blood (red cells) can be transfused to patients of all blood types. It is always in great demand and often in short supply.
  • Type AB plasma can be transfused to patients of all other blood types. AB plasma is also usually in short supply.
  • The blood used in an emergency is already on the shelves before the event occurs.
