Quick Answer
You can pre-check most plasma donation eligibility requirements online before making the trip to a center. Basic requirements are: age 18-69, weight 110+ lbs, generally healthy, and not taking certain medications. Most major plasma centers (CSL Plasma, BioLife, Octapharma, Grifols) have online pre-screening tools on their websites or apps. You can also use our quick-check guides below for age, weight, medication, and medical condition eligibility. Pre-checking saves you the frustration of a 2-3 hour first visit that ends in deferral for a preventable reason.

Why Pre-Check Your Eligibility Online?
Walking into a plasma center unprepared is one of the biggest mistakes first-time donors make. Here is why spending 10 minutes online before your visit saves hours of frustration:
The Cost of Not Pre-Checking
- Wasted time: A first-time visit takes 2-3 hours (registration, medical screening, physical, donation). If you are deferred for an easily discoverable reason (wrong medication, recent tattoo, etc.), you have wasted half your day
- Wasted travel: Gas, bus fare, or rideshare costs add up. If the nearest center is 15-30 minutes away, a deferral means wasted money on transportation
- Emotional frustration: Nothing is more discouraging than psyching yourself up for your first donation, sitting through the screening process, and being told you cannot donate. Pre-checking prevents this
- Missing documents: Many first-time deferrals happen because donors do not bring the right identification documents. Checking requirements online ensures you arrive prepared

Use this quick checklist to assess your eligibility before visiting any plasma center. If you can answer "yes" to all of the following, you are very likely eligible to donate:
Basic Requirements Checklist
- I am between 18 and 69 years old
- I weigh at least 110 pounds (50 kg)
- I am in generally good health and feel well today
- I have not donated plasma in the last 48 hours
- I have a valid photo ID (driver's license, state ID, or passport)
- I have proof of Social Security number (SSN card, W-2, or SSN-bearing document)
- I have proof of my current local address (utility bill, lease, bank statement, or mail)
Deferral Check: Answer "No" to All of These
- I have gotten a tattoo or piercing in a non-regulated facility in the last 3-4 months
- I am currently pregnant or breastfeeding
- I have had a blood transfusion in the last 12 months
- I have traveled to a malaria-risk country in the last 3-12 months
- I am currently taking antibiotics for an active infection
- I have been diagnosed with HIV, hepatitis B, or hepatitis C
- I have received a live vaccine (MMR, chickenpox, yellow fever) in the last 4 weeks
- I have been incarcerated for more than 72 hours in the last 12 months
If you answered "yes" to all items in the first list and "no" to all items in the second list, you have a strong chance of being eligible. However, final eligibility is always determined by the center's medical staff during your in-person screening.
Age and Weight Requirements
These are the most straightforward eligibility criteria, and they are universal across all plasma centers in the United States:
Age Requirements
| Age Range | Eligible? | Notes |
|---|---|---|
| Under 18 | No | All plasma centers require donors to be at least 18. No parental consent exception |
| 18-64 | Yes | Standard eligible age range at all centers |
| 65-69 | Usually yes | Most centers accept donors up to 69. Some require additional medical clearance for 65+ |
| 70+ | Varies | Some centers have an upper age limit of 69. Others evaluate donors 70+ on a case-by-case basis with physician approval |
Weight Requirements
| Weight Range | Eligible? | Plasma Volume Allowed |
|---|---|---|
| Under 110 lbs | No | N/A -- cannot safely donate |
| 110-149 lbs | Yes | 690 mL (smallest volume) |
| 150-174 lbs | Yes | 825 mL (medium volume) |
| 175-400 lbs | Yes | 880 mL (largest volume, highest pay) |
| Over 400 lbs | Varies | Some centers have an upper weight limit due to equipment capacity |
Why weight matters for pay: Heavier donors can safely give larger plasma volumes, which means they are compensated more per donation. Donors at 175+ lbs typically earn $10-$20 more per visit than donors at 110-149 lbs.

Medications are one of the most complex eligibility factors. Here is a simplified quick-reference for the most commonly asked-about medications:

- Over-the-counter pain relievers (ibuprofen, acetaminophen, naproxen)
Generally DEFERRED Medications

- Antibiotics -- deferred until course is completed and infection resolved

Frequently Asked Questions
Can I check my plasma donation eligibility online?
Yes. You can pre-check most basic eligibility requirements online, including age (18-69), weight (110+ lbs), medication compatibility, and medical condition status. Most major plasma centers (CSL Plasma, BioLife, Octapharma, Grifols) also have online pre-screening tools on their websites and apps. However, final eligibility requires an in-person screening with blood tests, vital signs, and a physical exam.
What disqualifies you from donating plasma?
Common disqualifications include: being under 18 or over 69, weighing under 110 lbs, having HIV or hepatitis B/C, taking blood thinners, being pregnant or breastfeeding, having a bleeding disorder, and recent tattoos from unregulated facilities. Some medications like Accutane require a temporary waiting period. Active infections requiring antibiotics also result in temporary deferral.
What documents do I need for my first plasma donation?
You need three things: a valid photo ID (driver's license, state ID, or passport), proof of Social Security number (SSN card, W-2, or SSN-bearing document), and proof of your current local address (utility bill, lease, bank statement, or mail with your name and address). Missing any of these documents will prevent you from donating on your first visit.
Can I donate plasma if I take medication?
Most medications are allowed, including statins, birth control, antidepressants, blood pressure medications, thyroid medications, allergy medications, and over-the-counter pain relievers. Medications that typically defer you include blood thinners (warfarin, Eliquis), Accutane, active antibiotic courses, and immunosuppressants. Always disclose all medications during screening.
How do I save time on my first plasma donation visit?
Pre-register online through the center's website or app (BioLife and CSL allow this). Bring all required documents (photo ID, SSN proof, address proof). Eat a protein-rich meal and drink 64+ oz of water the day before. Arrive at opening time when wait times are shortest. Pre-checking your eligibility online ensures you do not waste a trip on a preventable deferral.
