Supply of O-negative blood hits critical low at Bonfils Blood Centers

DENVER, Colo. - Bonfils Blood Center’s supply of O-negative blood type products has hit a critical low.

Officials say they only have a half-day supply of the rare blood that can be given to patients of any blood type.

Bonfils officials are asking O-negative donors to please give blood now.

This can be an especially serious problem leading up to the Christmas holiday.

Bonfils usually experiences a 20 percent decline across the board in donations as people become busy with holiday shopping, activities and travel, officials said.

Only 6.9 percent of the entire U.S. population has O-negative blood type -- the only type that can be transfused into patients before their own blood type is known.

One single blood donation can save and enhance the lives of up to three patients, the blood center says.

To donate, call Bonfils' Appointment Center at 303.363.2300 or 800.365.0006, opt. 2 or schedule an appointment online to give blood.

If you can’t donate blood but would still like to contribute to Bonfils’ lifesaving mission, please contact Bonfils’ Foundation at 303-739-4000 or by emailing
