DETROIT (WWJ) – The American Red Cross is encouraging eligible blood donors to give one last gift this holiday season — and discover the true meaning of giving — by donating blood.

The gift of a blood donation only takes about an hour and can give patients a chance to celebrate more holidays to come.

Eligible donors with all blood types are needed, especially those with type O negative, A negative or B negative.
