American Red Cross Declares National Blood Supply Crisis as Summer Donations Hit Four-Year Low

The American Red Cross declared a national blood supply crisis on August 5, 2026, citing a sharp drop in donations during the summer months. The organization said blood supplies have fallen to their lowest point in four years, with shortages affecting all blood types.

O-negative blood, which can be given to any patient regardless of blood type and is used most often in emergencies, is at critically low levels. O-positive, the most common blood type, is also in short supply. The Red Cross said it needs to collect an additional 10,000 units per day to meet current hospital demand.

Hospitals in several states have begun rationing blood for elective surgeries and non-emergency procedures. Trauma centers and cancer treatment facilities, which rely heavily on regular transfusions, are among the most affected.

Red Cross officials said the summer shortage is not unusual, but this year's decline is steeper than in previous years. Fewer blood drives at schools and workplaces, combined with increased demand from hospitals, have widened the gap between supply and need.

The organization is calling on eligible donors to schedule appointments immediately. First-time donors are especially encouraged to give, as the Red Cross said it needs to expand its donor base to prevent future crises.

Blood donation centers are open across the country, and the Red Cross has extended hours at many locations to accommodate more donors. Appointments can be scheduled online or by calling the Red Cross directly.

Medical experts said the crisis underscores the need for year-round donation campaigns rather than relying on periodic drives. Several health systems said they are partnering with the Red Cross to host on-site donation events for employees and patients.
