Every six minutes, a patient at Mayo Clinic needs a transfusion of blood or blood products. A simple blood donation can save the life of a child with leukemia, restore the strength of a cancer patient or provide a critical transfusion to an accident victim. There is no substitute for this life-saving gift, so our patients rely upon the caring spirit of blood donors like you. Volunteer donors are especially needed during the summer months, when an increase in elective and emergency surgeries means the demand for blood and blood products is also higher. Please consider making an appointment to donate blood today, and encourage friends, co-workers and family members to do so as well. For more information about who can donate, donor center hours, directions and parking, or to find mobile blood drives in your area, please check out our website.
