Frequently Asked Questions

Is it safe to be a healthy volunteer?

Yes, studies are closely monitored by the FDA and ethics committees. You'll receive thorough health screenings, and medical staff monitor you throughout. You can withdraw at any time.

Will this affect my health insurance?

No, participating in clinical trials as a healthy volunteer should not affect your health insurance. The study covers all medical costs related to the research.

How often can I participate?

Most studies require a 30-90 day washout period between trials. Some facilities maintain databases to ensure volunteers don't over-participate for safety reasons.

Can I leave a study early?

Yes, you can withdraw at any time for any reason. However, you may receive reduced or no compensation if you don't complete the study (unless withdrawing for safety reasons).

Volunteer Spotlight

"As a graduate student, participating in clinical trials helped me pay off my loans while contributing to science. Over 3 years, I've participated in 8 studies, earned over $25,000, and learned so much about drug development. The medical teams are professional, and I've never felt unsafe. It's rewarding knowing I'm helping develop treatments that could save lives."
