After a summer of declining donations, the American Red Cross needs the public’s help to prevent a blood shortage. When a donor makes and keeps an appointment to give blood in the weeks ahead, they can help ensure trauma patients, those undergoing cancer treatment, and people with lifelong blood disorders can get the blood they count on. Right now, the Red Cross especially needs type O negative, type O positive and type B negative blood donors. Donors of all blood types can schedule an appointment to give by downloading the Red Cross Blood Donor App, visiting RedCrossBlood.org or calling 1-800-RED CROSS (1-800-733-2767).
