Blood and heart CT scan tests for heart blood-flow markers
This study looks at whether certain lab “biomarkers” and a heart CT scan can help understand heart blood flow in people getting routine coronary CT angiography (CCTA). It may be useful for improving how doctors assess heart health from scan and blood results.
Maastricht, LimburgAges 18 years+ - NCT02573753Recruiting
Study how sleep affects gut bacteria and health
This study looks at how different sleep patterns change the microorganisms in your gut (gut bacteria) and what that may mean for health. It’s mainly for people who can take part in other approved research studies at the same time.
Rochester, MinnesotaAges 18 years+ - NCT02851043Recruiting
Non-invasive monitor to measure breathing

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 recruiting general population (no specific condition or disease) studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a general population (no specific condition or disease) trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a general population (no specific condition or disease) trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
