Between now and Christmas, more than one million units of blood could be transfused in the United States. Individuals are urged to give a lifesaving gift during the holidays by making an appointment to donate and help the American Red Cross. Those with type-O blood are urged to donate.

Set aside some time and make an appointment by downloading the free Red Cross Blood Donor App, visiting RedCrossBlood.org or by calling 1-800-Red-Cross.
