Donating Blood

Blood donors make a lifesaving difference. More than 4.5 million patients need life-saving blood transfusions each year in the U.S. and Canada. And blood is a perishable resource that can be stored only for a short time. That's why blood donors are needed every day.

Donor Requirements

You may be eligible to give blood every 56 days if you are a healthy person age 17 or older (or 16 with parent's/guardian's consent), weighing 110 pounds or more. Although, females age 18 and younger must weigh 120 pounds or more.
