hospitalDid you know thousands of people in the United States receive blood every day and their lives are either saved, prolonged or quality of life is improved. These people receive blood from unselfish strangers that they never meet. Won't you please consider becoming one of these strangers who help so many people?

The need for blood and platelets is a constant one both locally and nationally. When a disaster or emergency occurs, blood units that are readily available are desperately needed. New donations require days to be tested before becoming available for transfusion.  When you donate blood, your precious gift is given directly to a patient in need.

Stony Brook University Medical Center, along with other Suffolk County hospitals, uses tens of thousands of units of blood each year. According to Dennis K. Galanakis, MD, chief of Blood Services at Stony Brook University Medical Center, "Less than five percent of the people in the US who are able to donate actually do donate."

We welcome the members of the community to become donors and are extremely grateful to all of our employees, friends from the community and students who assist our Blood Bank.
