Different types pay different amounts. Here's what they are in plain English.
Researchers need specimens from real people with real conditions. The rarer your profile, the more you earn.
Your pay is based on what researchers need from you — not a flat rate. The more valuable your profile, the more you earn.
Blood is deeply personal. We built Helio to protect you by default — not as an afterthought.
Researchers get your specimen. Never your identity. Your name never leaves Helio.
Full compliance with federal health data protections. No exceptions.
We don't sell your data. Ever. Not to advertisers, not to insurance companies, not to anyone.

Loyalty bonuses on top of every payout.
Every condition, every background, every blood type — researchers are looking for someone exactly like you.
No. Your donation is anonymous and completely separate from your insurance. Researchers never see your identity. Nothing is reported to insurance companies.
$50–$650 per donation. Your first screening visit earns $50 and builds your Helio Score. After that, your pay depends on your health profile and what researchers need. Donors with conditions like diabetes, autoimmune disorders, or cancer often earn the most — because their blood is exactly what studies are looking for.
Your blood specimen is used for medical research — things like cancer studies, drug development, and disease detection. It's never sold commercially and never used for insurance purposes.
For standard research draws (about 40mL — less than a regular blood donation), you can donate every 2 weeks. Your body replaces this amount in days. Larger donations like leukopaks have longer intervals — typically every 4–8 weeks. We'll never schedule you more often than is safe.
Yes, 100% free. No signup fees, no hidden costs. You earn money — you never pay us anything.
You must be 18 or older to donate through Helio. There is no upper age limit — healthy donors of all ages are welcome.
In most cases, yes. Many medications actually make your blood more valuable for research — studies specifically need specimens from people on common medications like metformin, biologics, or immunosuppressants. Your health questionnaire captures this information so we can match you to the right studies.
Just a valid photo ID and your Helio confirmation email or text. The phlebotomist brings all medical supplies. Wear a short-sleeved shirt or something with sleeves you can roll up easily. Drink plenty of water beforehand.
It's a standard blood draw — the same thing you'd experience at a doctor's office. A trained phlebotomist uses a small needle in your arm. Most people feel a quick pinch. The whole draw takes about 10 minutes. Some people feel slightly lightheaded afterward, so we recommend having a snack and water handy.
You stay in our donor network and we'll notify you as soon as a matching study comes in. Many donors receive their first match within 1–2 weeks. Donors with common conditions (diabetes, autoimmune) tend to match faster because demand is highest for these profiles.
