WASHINGTON (WUSA) -- The American Red Cross received 50,000 fewer donations than expected in June, leaving the organization with half the readily available blood supply compared to this time last year.
The Red Cross is calling on emergency donations for all blood types, but especially O positive, O negative, B negative and A negative in order to meet patient demand this summer.
"Blood must be available at a moment's notice when seconds count to help save or sustain a life. We have reached an emergency situation and the blood will not be there without the immediate response of volunteer blood donors," said Donna M. Morrissey, Director of Communications of American Red Cross Blood Services - Northeast Division, in a press release.
The Northeast Division, that encompasses 11 states from Maine to Washington D.C., is seeking to collect almost 50,000 blood donations over the next two weeks.
Approximately every two seconds, a patient in the United States needs a blood transfusion.
