How it works

As a recipient

By age 72, about 95 percent of all Americans will have received a blood transfusion at some point. The blood that you (or a member of your family) receive comes from the Blood Center. When you are able, please consider making a donation yourself, making blood available for the next patient needing a transfusion. All types of blood are needed, all the time.

As a donor

Every healthy adult has enough blood that the donation of one pint will cause no physical harm. The human body replaces this blood quickly. A person can donate blood as often as every 8 weeks. One pint of blood can save three lives. There is no substitute for blood.

Donors must be at least 17 years old, weigh at least 110 pounds and be in good general health.

• Have tested positive for HIV/AIDS
