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 Los Angeles region, blood is always in high demand though less than 2 percent of the population donates. With just one donation, you can help save multiple lives.
