STANFORD, Calif. — Bay Area residents are being asked to donate type O blood at Stanford Blood Center (SBC) to meet the immediate and ongoing need for life-saving O blood products.

Stanford Blood Center has been supporting a number of patients who have required large amounts of blood products, and now has a critically low supply of both O positive (O+) and O negative (O-) blood.

“Last week alone, patients at our local partner hospitals required more than 1,000 units of red blood cells, including over 170 units of O- red blood cells (RBCs),” said Dr. Tho Pham, Chief Medical Officer at Stanford Blood Center. “In addition, we supported multiple heart and liver transplant patients who required approximately 125 units of O+ RBCs, as well as emergent and trauma patients who used more than 50 units of RBCs.”

Donors with all blood types are always welcomed and appreciated, but type O+ and type O- are needed most now.

“When we’re sending out more blood products than we are taking in due to high need at our partner hospitals, we reach out to our current, dedicated group of donors as well as the larger community to help replenish the blood supply to sustainable levels,” says SBC spokesperson Ross Coyle. “We urgently need O+ and O- blood to be able to meet the needs of local patients, so we’re calling on donors to make their earliest available appointment. All it takes is about an hour of your time, and you can help save the lives of up to three patients with a single donation.”

Donors are encouraged to walk in to one of three donation center locations in Campbell, Menlo Park, or Mountain View. Appointments can be scheduled online at or by calling 888-723-7831 for same-day appointments.
