It’s easy to become a blood donor. Individuals who are in good health and can meet the general eligibility criteria are likely able to donate. If you were deferred from donating in the past, you may be able to donate again.

As part of our commitment to safety, blood donors must meet certain requirements to give blood. Prior to scheduling an appointment to give blood, review the eligibility requirements and prescreening questions. The guidelines listed below are not all-inclusive and are subject to change.

If you have any questions regarding your eligibility, please contact Bonfils’ Donor Relations department at 303.363.2202 or 800.365.0006, opt. 1.
