The American Red Cross has declared a national blood supply crisis, warning that donations have dropped to a four-year summer low and leaving hospitals in the Washington, DC, area and across the country facing dangerously thin reserves.
The American Red Cross announced the crisis July 27, 2026, reporting that it now holds less than a one-day national supply of type O positive blood, the most commonly transfused blood type. To protect patients in the most urgent, life-threatening emergencies, the organization has begun limiting distributions of type O blood to individual hospitals.
Type O blood remains the top priority. It accounts for about 60% of American Red Cross distributions. Type O positive can be safely given to roughly 80% of patients, while type O negative serves as the universal type relied upon when there is no time to determine a patient’s blood type.
Officials stress, however, that a steady supply of every blood type also matters. When hospitals keep adequate stocks of A, B and AB blood, they can preserve scarce type O units for emergencies. Maintaining that balance, the American Red Cross says, depends on volunteer donors of every type giving regularly.
Blood donations are not keeping pace with hospital demand, which rises during the summer trauma season. Officials point to extreme heat, poor air quality and widespread foodborne illnesses as factors driving down donor turnout this summer.
“Blood donations simply are not keeping pace with hospital demand, and inventories — especially type O blood — remain under significant strain,” said Chris Hrouda, president of American Red Cross Biomedical Services. “Every donation has the potential to help save lives, and we urgently need everyone who is eligible to make an appointment to give blood as soon as possible.”
The current shortage marks only the second time the Red Cross has declared a national blood crisis. The first came in January 2022. Since then, the organization added prevention measures, including closer planning with hospital partners, but elevated demand and ongoing collection challenges pushed supplies back to crisis levels.
The American Red Cross says the solution may be simpler than it sounds. Just three more donors at each blood drive this summer could end the crisis and stabilize the supply.
How to Donate
Eligible donors, particularly those with type O blood, are urged to give as soon as possible. Anyone who cannot secure an immediate appointment is encouraged to schedule a donation in the days and weeks ahead.
