Check Your Eligibility

A donor is deferred when they don’t meet one or more eligibility criteria. It’s how long they must wait before being considered for donation again. For example, when you get a tattoo, you’ll be deferred for a week. That means you can donate blood one week after it was done.   

Or you may receive an indefinite deferral, where you aren't able to donate blood unless federal regulations change in the future. We understand this isn’t what you want to hear, but you can still help us save lives. Follow us on social media and emphasize the importance of donating blood and/or volunteer to help us recruit donors.   

Note: One of the most common reasons a donor is deferred is because of low iron. Learn more here.   

• Wait if you have a fever or a productive cough (bringing up phlegm).
• Wait if you do not feel well on the day of donation.

This list is NOT a complete list of countries, but it includes the most visited countries.

U.S. Food and Drug Administration (FDA) officials announced changes in April 2020 that affect donor eligibility. The deferral period for people who have traveled to malaria-endemic areas has been shortened from a year to three months. (Travel is defined as a stay greater than 24 hours.) 

A three-year deferral is in place for donors who lived 5 years or more consecutively in a malaria endemic risk area.
