July 4, 2012 - The American Red Cross desperately needs more people to roll up their sleeves and donate blood. In June, the agency reported its supply had reached emergency levels. The Red Cross says all blood types are welcome, but there's a particular need for O positive, O negative, B negative and A negative to meet expected patient demand this summer. Type O negative is the universal blood type and can be transfused to anyone who needs blood. Everyday, the Red Cross must collect more than 17-thousand pints of blood for patients in need across the country.
