How Weight Affects Your BioLife Pay

Your body weight directly determines how much plasma BioLife can safely collect per donation. The FDA sets strict limits on plasma collection based on your total blood volume, which correlates with weight.

The Science Behind Weight-Based Pay

Your total blood volume is approximately 7% of your body weight. The FDA allows plasma centers to collect up to 13% of your total plasma volume per donation. Heavier donors have more blood and plasma, so they can safely donate larger volumes.

Lighter Donors (110-149 lbs)

  • • Estimated blood volume: ~8-10 pints
  • • Plasma collected: 690 mL maximum
  • • Donation time: ~35-45 minutes
  • • Typical pay: $50-$65 per visit

Heavier Donors (175+ lbs)

  • • Estimated blood volume: ~12-14+ pints
  • • Plasma collected: 880 mL maximum
  • • Donation time: ~45-60 minutes
  • • Typical pay: $60-$80 per visit

FDA Plasma Volume Limits Explained

The Food and Drug Administration (FDA) sets strict guidelines on plasma collection to ensure donor safety. Here's how the limits work:

Body Weight (lbs) Body Weight (kg) Max Plasma/Donation Max Plasma/Week
110-149 lbs 50-67 kg 690 mL 1,380 mL
150-174 lbs 68-79 kg 825 mL 1,650 mL
175+ lbs 80+ kg 880 mL 1,760 mL

Why These Limits Exist

The FDA limits protect donors by ensuring only a safe percentage of total plasma is collected. Your body replaces plasma within 24-48 hours, but these limits prevent overcollection.

Maximum Donation Frequency

You can donate plasma up to twice per week (every 7 days), with at least one day between donations. This applies to all weight categories.

What Happens If Your Weight Changes?

Weight Gain

If you cross into a higher weight tier (e.g., from 148 lbs to 152 lbs), your plasma collection volume and pay will increase. BioLife weighs you at every visit.

Weight Loss

If your weight drops to a lower tier, your collection volume and pay decrease. If you fall below 110 lbs, you'll be temporarily deferred until your weight increases.

Weight Fluctuation

Normal daily fluctuations (1-3 lbs) usually don't affect your tier unless you're right at a threshold. Weigh yourself before donating if you're close to a tier boundary.

Tip for Borderline Weights

If you're close to a tier boundary (like 149 lbs or 174 lbs), eating a meal and staying hydrated before your visit can help you reach the next tier for higher pay.

Maximizing Your BioLife Earnings at Any Weight

For Lighter Donors (Under 150 lbs)

  • Donate consistently twice weekly to maximize monthly totals
  • Take advantage of ALL new donor bonuses - they're weight-neutral
