The American Red Cross urges eligible donors to help ensure a sufficient blood supply for patients by giving blood this February.During the winter months, inclement winter weather and seasonal illnesses can keep regular donors from giving blood. Healthy donors of all blood types are needed to help maintain an adequate blood supply for patients in their own communities as well as areas where donors were unable to give due to severe winter weather. Individuals with types O, AB, B negative and A negative blood are especially needed.Donor Loretta Brandon knows how important it is to have a readily available blood supply.
