2026 Plasma Weight Tiers
110-149 lbs | 150-174 lbs | 175+ lbs
Master Plasma Donation Weight Chart 2026
Your weight directly determines how much plasma centers can collect and how much you get paid. The FDA sets strict volume limits based on body weight to ensure donor safety. Here's the complete breakdown:
| Weight Range | Plasma Volume | Pay Per Visit | Monthly (8 visits) |
|---|---|---|---|
| 110-149 lbs | 690 mL | $40-$65 | $320-$520 |
| 150-174 lbs | 825 mL | $50-$80 | $400-$640 |
| 175+ lbs | 880 mL | $60-$100 | $480-$800 |
Key insight: A 175+ lb donor earns $100-$280 MORE per month than a 110 lb donor at the same center. That's $1,200-$3,360 more per year!
Four things that stop you losing a payment
A deferral costs the whole visit, and almost all of them come down to iron, protein or hydration. These are the cheapest ways to keep yourself eligible.
Nature Made Iron 65 mg Tablets
Under $25
Low hematocrit is the most common reason a donation gets turned away, and a deferral costs you the whole visit. This is the cheapest insurance against losing a payment.

Optimum Nutrition Gold Standard Whey
Under $50
Plasma is mostly protein, and low protein is the second most common deferral. A scoop a day is far cheaper than a wasted trip.

Ultima Replenisher Electrolyte Packets
Under $25
Hydration is what decides whether the draw runs fast or you sit there for an hour. Electrolytes work better than plain water for this.

Compression Arm Sleeves
Under $25
Wearing one after the draw is the simplest thing that reduces bruising, which is what makes frequent donors stop.

| Weight (lbs) | Weight (kg) | Est. Blood Volume | Max Plasma/Donation | Max Plasma/Week |
|---|---|---|---|---|
| 110-149 | 50-67 | 4.0-5.2 liters | 690 mL | 1,380 mL |
| 150-174 | 68-79 | 5.3-6.0 liters | 825 mL | 1,650 mL |
| 175+ | 80+ | 6.1+ liters | 880 mL | 1,760 mL |
Why Heavier Donors Get Paid More
- More plasma = more pay: A 175+ lb donor provides 28% more plasma per donation than a 110 lb donor
- Same time investment: Donation only takes 10-15 minutes longer
- Pharmaceutical value: Plasma centers can produce more medicine from larger donations
Maximizing Earnings at Any Weight
For Lighter Donors (110-149 lbs)
- Focus on new donor bonuses - These are weight-neutral ($900-$1,500 first month)
- Use referral bonuses - Some centers advertise $50-$150 per friend regardless of your weight
- Watch for flat-rate promotions - Holiday bonuses often pay the same for all weights
- Donate consistently - 8 donations/month maximizes your monthly total
For Heavier Donors (175+ lbs)
- You're already in the top tier - Focus on consistency
- Stack promotions - New donor bonus + high weight = maximum first month
- Stay hydrated - Faster flow rate = shorter donation time
- Protein-rich diet - Helps plasma regenerate faster between donations
At Weight Thresholds (148-149 or 173-174 lbs)
- Eat before your appointment - A full meal can add 1-2 lbs
- Stay hydrated - Water adds weight temporarily
- Weigh yourself at home first - Know where you stand before arriving
- Afternoon appointments - You naturally weigh more later in the day
Frequently Asked Questions
What is the minimum weight to donate plasma?
The minimum weight to donate plasma is 110 pounds (50 kg). This is an FDA requirement that applies to all plasma centers in the United States. If you weigh less than 110 lbs, you cannot donate plasma at any center.
What is the BioLife plasma donation weight chart?
BioLife pays $45-$55 (first visit of the week) and $55-$70 (second) at 110-149 lbs, $50-$65 and $70-$85 at 150-174 lbs, and $55-$75 and $80-$100 at 175 lbs and up, which is about $400-$700 a month at 8 donations. The minimum weight is 110 lbs at every BioLife center. See the full BioLife weight chart.
What is the BioLife weight limit to donate plasma?
The minimum is 110 lbs, the same FDA floor used at every center. There is no strict maximum at BioLife; donors need to fit the donation chair safely, and everyone 175 lbs and over is paid at the top tier because the 880 mL collection limit does not rise past that weight.
Is there a maximum weight for plasma donation?
Most centers don't have a strict maximum weight limit, but donors must be able to fit comfortably in donation chairs. Some centers accommodate donors up to 400+ lbs. All donors over 175 lbs receive the same maximum plasma volume and pay tier.
Do plasma centers weigh you every time?
Yes, plasma centers weigh you at every donation as part of the health screening process. Your weight determines the plasma volume collected that day, so pay can fluctuate if you're near a weight threshold.
Can I gain weight to earn more from plasma?
While crossing into a higher weight tier does increase pay, intentionally gaining weight just for plasma income isn't recommended for health reasons. However, if you're close to a threshold (like 148 or 173 lbs), eating a meal and staying hydrated before your visit can help you reach the next tier.
Why does my weight affect plasma donation pay?
FDA regulations limit plasma collection based on body weight to ensure donor safety. Heavier donors have more blood volume, so they can safely donate more plasma. More plasma = more pharmaceutical products = higher pay for the donor.
Do new donor bonuses vary by weight?
No! New donor bonuses are typically the same regardless of weight. A 115 lb new donor and a 200 lb new donor both qualify for the same $900-$1,500 first-month bonus at most centers.
