At a Glance

As a unique provider of health care services for the community, Bloodworks Northwest collects, tests and distributes lifesaving blood to more than 90 hospitals in the Northwest. We’re transfusion experts who consult with physicians. We are lab experts who support patients receiving organ transplants and cancer treatment. We’re medical professionals who deliver clinical care to patients with bleeding disorders and blood disease. We’re a Research Institute of scientists, with a legacy of medical breakthroughs. We are a respected center of excellence for everything related to blood.

Here are some of the ways we’re saving lives every day:

Your Community Resource For Lifesaving Blood

With the help of 230,000 registered donors and volunteers in the region, Bloodworks collects about 800 units of blood each day. All blood receives immediate, comprehensive testing so that it can be available to more than 90 regional hospitals – usually in less than 24 hours after donation. We operate 12 donor centers and our mobile units travel to hundreds of blood drives every month at work sites, schools, places of worship, and other community locations throughout Western Washington.


Bloodworks benefits from the dedicated work of 3,000 active volunteers. Volunteers welcome donors, assist with donor registration and monitoring, phone scheduling, transportation and administrative tasks. Our volunteers make a real difference to the community. Their vital contribution helps save lives, while they give back to the community, gain work experience, build skills, earn community service hours and feel justifiably proud about helping people in need.

Investing in our Mission

As a local, independent, community-based nonprofit organization, we rely on public support. Financial contributions help guarantee the delivery of essential blood services and transfusion expertise, as well as advancing our blood research and services for patients. Your contribution can be designated for a specific program, for activities or special projects. We’re deeply grateful to all who support our work.

Transfusion Medicine Experts

Bloodworks operations are an essential component of the region’s healthcare system – providing a safe, stable and community-based blood supply for Northwest communities. Our physicians are transfusion experts, available to hospitals 24/7 for consultation on challenging cases. Our transfusion safety officers work in hospitals to ensure that blood transfusions are performed according to current best medical practices.

Patient Services

Our team of physicians and nurses is recognized as premier specialists in the therapeutic application of apheresis—procedures that separate blood into its components. The team is available 24/7 to perform therapeutic plasma exchanges, cell depletions, outpatient transfusion services, peripheral blood stem cell collections, and red cell exchanges.

Washington Center for Bleeding Disorders

Established in 1974, our treatment center for hemophilia and bleeding disorders offers comprehensive services to hemophilia patients including physician and nursing care — as well as statewide clinics, educational outreach, counseling, physical therapy and home infusion training.

Laboratories and Immunogenetics

Our multiple labs offer diverse services to healthcare providers. We genotype and phenotype donor blood and platelets from thousands of donors annually to provide blood that is a “perfect match” for transplant patients and for patients with complex blood types. We perform diagnostic testing of patients with bleeding disorders, undertake clinical trial work, partner with hospital transplant programs, and support innovative studies with the Bloodworks Research Institute.
