The American Red Cross asks eligible donors to make an appointment to give blood to help ensure sufficient blood supplies are available for patients this holiday season. The Red Cross says blood donations often decline during the holidays when donors get busy with travel and family gatherings, but the need for blood remains steady. Eligible donors with all types are needed, especially those with O negative, A negative and B negative.
