Thousands of people have responded to the emergency call for blood and platelet donations issued by the American Red Cross in early July.

Still, there continues to be an emergency need for donors of all blood types, especially type O, to give now to address a severe blood shortage, the Red Cross said in a recent press release.

Red Cross blood donations are being distributed to hospitals faster than they are coming in, and right now there is less than a five-day blood supply on hand. The Red Cross strives to keep a five-day supply of blood to meet the needs of patients and to be prepared for emergencies that require significant volumes of donated blood products.

There is a particular need for type O blood, which plays an important role in ongoing patient care and emergencies. Type O positive is the most transfused blood type and can be given to patients with any Rh-positive blood type. Type O negative is the universal blood type and can be given to any patient. It’s what emergency room personnel reach for when there is no time to determine the blood type of patients in the most serious situations.
