O-negative blood is the universal blood type and can be transfused into any patient, according to We Are Blood. Platelets are a component of blood that aid in clotting and are often used to help trauma and cancer patients. They have a shelf life of five days, which makes maintaining a steady supply difficult.
Eligible donors must be healthy and at least 17 years old and 115 pounds.
We Are Blood has locations in North Austin at 4300 N. Lamar Blvd. and South Austin at 3100 W. Slaughter Lane.
