Contact the research site through the registry page, complete a short phone screen, then attend an in-person screening visit. If you qualify, the study team walks you through the informed consent document, which details every procedure, risk and payment before you commit. You can withdraw at any point, and enrollment is always free.

Frequently asked questions

How much do paid clinical trials in Hartford pay?
Compensation varies by study length, procedures and overnight stays. Industry surveys report typical payments from $75 to $4,500 per completed study, with simple observational studies at the low end and multi-week inpatient Phase 1 studies at the high end. Each listing's study team will confirm the exact amount before you enroll.
Do I need to be sick to join a clinical trial in Hartford?
No. Many studies recruit healthy volunteers, especially early-phase studies run at dedicated research centers. Others need participants diagnosed with a specific condition. Every trial lists its eligibility criteria — age range, condition, medications — and the study team screens you before enrollment.
What is the difference between a research center and a hospital study in Hartford?
Dedicated research centers (listed on this page with their Google ratings) run studies as their core business — often healthy-volunteer and vaccine studies with structured compensation. Hospital and university studies tend to focus on patients with specific conditions. Both types are registered and IRB-supervised.
How often do new paid studies open in Hartford?
Constantly — trials open and close enrollment every week. This page is refreshed weekly from the NIH registry. Join the email alert to be notified when a new study opens within 30 miles of Hartford.
Can I be in more than one clinical trial at a time?
Generally no — most studies exclude participants currently enrolled in another trial, and paid Phase 1 studies enforce a washout period (often 30 days or more) between studies. Frequent healthy volunteers in Hartford typically complete one or two studies per year.
