When you donate plasma, you’re helping to save lives. It’s no wonder donors like you are often eager to give, whether it’s your first time or you’re coming back again. We’re right there with you—we want every appointment to result in a successful donation!
Because safety is our top priority, donation centers may occasionally ask donors to wait before giving plasma. This is called a deferral, and it’s nothing to worry about if it happens to you. Many donors are deferred at some point along their donation journey. It doesn’t mean you won’t be back to making a difference in the very near future. It just means you weren’t quite ready to donate at that moment.
Below, you’ll find everything you need to know about deferrals, what to do if you’re asked to wait a bit before donating again, and how to boost your chances for a successful donation the next time you come to visit us at a center.
Deferrals are all about keeping you, and the people who will end up receiving plasma, safe. If you’re ever unsure why you’re being asked to wait, just chat with one of our team members. We’re here to help make sure you can donate as soon as possible!
A few things to keep in mind:
Safety comes first. Deferrals help make sure that it’s safe for you to give plasma, and that plasma only comes from healthy donors.
Recovery time matters. Your body needs time to recover, which is why we ask you to wait at least one calendar day between your donations. This waiting period applies to every donor and is not a deferral.
The good news? Most deferrals are temporary, so you’ll likely be back to donating again very soon. Here are some common reasons you might be asked to wait:

Temporary deferrals can last from one day (for blood pressure issues) to several months for tattoos, travel concerns, or pregnancy. Check your BioLife app (Apple/Android) or contact your center to see when you can return.
Permanent deferrals are rare but can happen. The most common reasons for a permanent deferral are testing positive for illnesses (like HIV or hepatitis) or having serious medical conditions. If you’re ever unsure about your status, our team is here to help!
A deferral is usually nothing to worry about. It’s often just a small speed bump on your donation journey. Our staff will do all we can to get you back in to donate safely, but you can also help speed up the process.
Ask questions: We understand a deferral might be unexpected or confusing. Our staff does all they can to help you understand your status and how to become eligible again.
Take action: We’ll be right beside you, offering helpful tips to get you ready for your next visit. These tips may include things like waiting until you’re well or completing treatments. If diet, hydration, illness, or medication triggered the deferral, we encourage you to address the cause of the delay and try again soon. Remember: A low iron level or dehydration can often be fixed within just a few days.
Now that you’ve learned a bit more about how our commitment to safety can lead to deferrals, we hope that you will use this information to help prevent delays when you arrive to donate plasma with BioLife. Please also remember that a delay/deferral is typically just a temporary speed bump along your donation journey. If one does happen, we’re here to get you right back on track.
