The Red Cross says its blood supply has reached the lowest point in 15 years after a dismal June in which the organization received 50,000 less donations than expected.
"There is always the chance that a physician could postpone an elective surgery if the needed blood products arent readily available," said Dr. Richard Benjamin, chief medical officer for the American Red Cross.
"In a worst case scenario, a physician may have to forego performing a more serious procedure for a patient because of a shortage of blood. We need to do everything we can to make sure it doesnt get to that point."
While all blood types are currently needed, donors with O positive, O negative, B negative and A negative are in highest demand.
Anyone wishing to donate can call 1-800-RED CROSS (1-800-733-2767) or visit redcrossblood.org to make an appointment or for more information.
