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.
Your health data stays yours. Always. Delete your account anytime — we erase everything.
Partner clinics in major metros. More cities coming soon.
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.
