The American Red Cross is experiencing a national blood shortage.

Fewer donors than needed gave this summer, drawing down the national blood supply and reducing distributions of some of the most needed blood types to hospitals.

Hurricane Idalia further strained the blood supply with blood drive cancellations and reduced blood and platelet donations in affected areas.

Donors of all blood types are urgently needed, and there is an emergency need for platelet donors and type O blood donors to make an appointment to give now to ensure patients across the country continue to receive critical medical care.

Right now, blood product distributions to hospitals are outpacing the number of blood donations coming in.

The Red Cross needs blood and platelet donors now. Schedule an appointment to give by downloading the Red Cross Blood Donor App, visiting RedCrossBlood.org or calling 1-800-RED CROSS (1-800-733-2767).

In thanks for helping rebuild the blood supply, all who come to give through Sept. 18 will receive a limited-edition Red Cross T-shirt, while supplies last.

A blood donor card or driver’s license or two other forms of identification are required at check-in. Individuals who are 17 years of age in most states (16 with parental consent where allowed by state law), weigh at least 110 pounds and are in generally good health may be eligible to donate blood.

High school students and other donors 18 years of age and younger also have to meet certain height and weight requirements.
