DENVER — Bonfils Blood Center has issued an urgent call for potential blood donors across Colorado, especially those with type O-negative blood, to help overcome a critically low supply because of a recent surge in blood use at various hospitals.

As of Wednesday afternoon, Bonfils said it had less than a one-day supply O-negative blood and between a one- and three-day supply of most other blood types. Bonfils strives to keep a four-day supply of most blood types available to expect the unexpected.

O-negative blood is especially in high demand because it is the only blood type that can be transfused before a patient’s own blood type is known.

Any Bonfils donor who gives blood until Oct. 12 is eligible to attend Bonfils’ Drive for Life, Colorado’s largest single-day blood drive held at Sport Authority Field at Mile High, and have the chance to mingle with Broncos players, alumni, cheerleaders and Miles, the Broncos’ mascot.

To make an appointment, call the Bonfils Appointment Center at 303-363-2300 or 800-365-0006 option 2, or visit to find a donation location.

According to Bonfils, some 70,000 Coloradans regularly donate blood, but many more are eligible. Donors can be as young as 16 years old with parental permission.

Bonfils provides blood supplies to more than 100 hospitals at Colorado and beyond.
