The Red Cross of Washington and Blood Works NW need a lot of blood to save lives. Supplies are dangerously low for O-Negative and B-Negative.
From the Seattle Times:
The American Red Cross needs at least 11,500 more type-O blood donations than it currently has to sustain a sufficient blood supply, according to the organization. Six units of the blood type are currently available for every 100,000 people each day, but at least 14 units are needed.
Type O-negative blood can be transfused to any patient, so it’s often used when hospital staff don’t know a patient’s blood type. Type O-positive blood is the type used most often in transfusions, according to the Red Cross.
