Just as most cars need to be refueled constantly, so does the nation’s blood supply. The American Red Cross has faced a concerning drop in blood and platelet donations this summer. Donors are needed to make an appointment to give in August to help prevent a blood shortage. The decline in donations has caused the Red Cross blood supply to shrink by nearly 20% in recent weeks. The availability of blood products will continue to decline if donations do not increase. People should not wait until they hear there is a blood shortage to give. Type O negative blood donors and platelet donors are especially needed now. By scheduling and keeping appointments in August, donors can help provide for those in immediate need of lifesaving care. Donors can schedule an appointment to donate using the Red Cross Blood Donor App, by visiting RedCrossBlood.org, or by calling 1-800-RED CROSS (1-800-733-2767).
