How can you save a life this summer? By being a blood or platelet donor! The American Red Cross is asking donors to make a blood or platelet donation appointment to help power the blood supply through mid-summer. While all blood types are needed, donors with type O blood are most urgently needed. Type O negative blood is often reached for in emergencies when there isn’t time to match a patient’s blood type. Type O positive is the most common blood type, so it’s important to keep type O blood and all blood types on hand at hospitals for people facing both chronic illness and sudden, life-threatening conditions. Add a blood or platelet donation appointment to your summer calendar today by visiting RedCrossBlood.org, by calling 1-800-RED CROSS or by using the Red Cross Blood Donor App.
