The American Red Cross needs blood and platelet donors to help restock the blood supply this February. Severe winter weather throughout January across much of the country forced the cancellation of about 770 Red Cross blood drives, resulting in more than 25,000 uncollected blood and platelet donations. On average, the Red Cross must collect about 15,000 units of blood every day for patients at approximately 2,700 hospitals and transfusion centers across the country. With additional winter weather already forecast for parts of the country in the next week or two, all blood types are currently needed to ensure a sufficient blood supply is available for patients. There is an urgent need for blood types O positive, O negative, A negative and B negative. Eligible donors with these blood types are strongly encouraged to make an appointment to give in the coming days.
