As holiday celebrations continue, concern is rising for the nation’s blood supply, which has now dipped to concerning levels and could force hospitals to hold off on essential blood transfusions for patients.

Historically low blood supply levels not seen in more than a decade persist for the American Red Cross, which supplies about 40% of the nation’s blood. The ongoing decline comes at a time of year when donations typically fall. Holiday get-togethers, school breaks and winter weather often lead to lower donor turnout, potentially further compounding the situation.

Potential donors are urged to schedule an appointment now by using the Red Cross Blood Donor App, visiting RedCrossBlood.org or calling 1-800-RED CROSS (1-800-733-2767). If there is not an immediate opportunity available to donate, donors are asked to make an appointment in the days and weeks ahead to ensure the Red Cross can replenish and then maintain a sufficient blood supply.

In thanks, all who come to give through Jan. 2 will receive an exclusive Red Cross long-sleeved T-shirt, while supplies last.

Those who come to give blood, platelets or plasma in January will automatically be entered for a chance to win a getaway to Super Bowl LVI in Los Angeles.
