Compensation & what to expect
- How payment typically works
- Compensation is most often provided through reloadable electronic study cards or direct deposit, paid out per completed visit rather than as a lump sum. Amounts vary by the time required, the number of visits, and the study's complexity — overnight stays and inpatient pharmacology studies generally pay more than short outpatient surveys. The exact amount is disclosed in writing during informed consent before any visit.
- Healthy volunteers
- Healthy participants aged 18 and older can earn compensation by joining vaccine, pharmacology, and biomarker studies in Washington D.C.. These trials check how a new drug or vaccine behaves in healthy bodies before later-phase testing. Many sites maintain a healthy-volunteer registry so you hear about new opportunities first.
- What's included beyond payment
- Most trials cover study-related medical care at no cost — physical exams, lab work, imaging, the investigational treatment itself, and follow-up visits with the research team. Insurance is not required to participate. Free check-ups and access to specialists are common reasons participants return for additional studies.
- Travel and time
- Many sponsors reimburse travel, parking, mileage, and lost wages for visit days. Long-running studies and trials that require frequent visits often raise stipends accordingly. Ask the study coordinator for the visit schedule and reimbursement policy before you commit.
- Asking about compensation
- Compensation is set per protocol and per site, so figures are not published in trial registries. The fastest way to confirm payment for a specific study is to contact the recruiting site listed on the study record. Coordinators are accustomed to this question and will quote the per-visit and total amounts up front.
