Immune aging

A paid research study on how the immune system changes with age. We measure it in the same people, over years, from their homes. Recruiting adults 18–30 and 50–75.

  • Every visit at home. A phlebotomist comes to you.
  • One blood draw per visit. No clinic, no procedures.
  • $100 for every completed visit. Each one is paid separately.

About the study

This study needs both ends of adulthood. Two people the same age can have immune systems that look decades apart. Nobody fully knows why. To explain it, science needs to watch immune systems age – which means measuring them at both ends of adulthood, across the whole range of how people experience it.

To qualify, you must be:

  • Ages 18–30

    The reference point. Healthy adults, measured near the immune system's peak – the baseline that every later change is read against.

  • Ages 50–75

    Where change shows. We want the full range of health here – people who feel well, people managing a condition, and everyone in between – because aging doesn't happen one way.

Same visits, same measurements, one dataset – so an immune system at 70 can be read against one at 25.

What we ask of members.

  • Sharing health data and medical records
  • Completing study visits for sample collection
  • Offering feedback on research findings

What members receive.

  • Research updates. Discover how everyday factors shape immunity from the study you helped make possible
  • Fair cash compensation. For completing study visits (e.g. blood sample)
  • Early access to future research developments. Opportunity to explore new research tools and discoveries developed through Onyx research

How it works

    We coordinate a mobile phlebotomy visit to your home. No clinic visits required.
  4. 04

    Compensation

    Receive cash compensation for your time.
  5. 05

    Analyze

    We analyze your sample in our Berkeley lab. Your data helps advance research.

  • Research Lab

  • Founders

    UC Berkeley PhDs

  • Data handling

    Privacy-first

  • Ethics board oversight

How often we'll ask.

Members complete at least one study visit a year. Between those, we may invite you back around events we want to measure: an illness, a vaccine, a course of antibiotics. Every visit is short, happens at home, and is paid: $100 per completed visit.

  • Every invitation is optional — decline any one without leaving the study

  • Every visit is compensated separately

  • The only thing you're committing to today is the first one
