Test for reflux causes after proton pump pills fail
This study checks whether a special test of the esophagus after meals can find the exact reason for ongoing reflux symptoms when proton pump pills (PPIs) don’t help. It may help doctors choose the right next treatment for people whose reflux symptoms keep coming back.
Chambray-lès-ToursAges 18 years+ - NCT07821190Recruiting
Blood marker for late infection in preterm babies
This study tests a new blood marker (called MDW) to help doctors quickly spot late-onset sepsis in preterm babies. If it works, it could lead to faster treatment for infections in premature infants.

A folate-based PET scan for suspected heart inflammation or infection
This trial tests a new imaging tracer called folate PET to see if it can help diagnose two heart conditions: cardiac sarcoidosis (inflammation in the heart) and infective endocarditis (infection on heart valves). If successful, it could offer a more accurate and targeted way to spot these problems early.
TurkuAges 18 years+ - NCT07813832Recruiting
Recovery study after knee or hip replacement
This study looks at why some people have problems after knee or hip replacement surgery. It follows patients for three years to understand complications and improve care.
MoscowAges 45 years+ - NCT07810686Recruiting
Smartphone AI help for reading heart rhythms in the field
This study tests a smartphone app that uses artificial intelligence (AI) to help prehospital care providers like you interpret electrocardiograms (ECGs), which are heart-rhythm recordings. If the app works well, it could help you make faster and more accurate decisions when caring for patients in the field.
Murten/Morat, Canton of FribourgAges 18 years+ - NCT07813884Recruiting
Study of a new treatment and blood test for colorectal cancer
This study looks at a new drug that may help treat colorectal cancer, and also tests a blood marker that could help diagnose it. It is for people who are already scheduled to have their colorectal tumor removed with surgery.
NiceAges 18 years+ - NCT07810920Recruiting
Ultrasound with AI to improve diagnosis
This study uses artificial intelligence to make ultrasound scans more accurate for diagnosing conditions like endometriosis and other uterine problems. If you're planning fertility treatment or surgery, this could help doctors find issues earlier.
Budapest, BudapestAges 18–45 - NCT06197204Recruiting
Finding biomarkers in Langerhans cell histiocytosis
This study is looking for adults with Langerhans cell histiocytosis (LCH) and also for adults with certain lung conditions (like cystic lung disease or emphysema) or healthy smokers to act as controls. The goal is to find biomarkers (signs in the body) that can help doctors diagnose LCH, predict how it will progress, and see how well treatment is working.
ParisAges 18 years+ - NCT07808619Recruiting
AI health data study for adults
This study is collecting health data to train an AI system that may help predict or improve health outcomes. By joining, you help develop technology that could benefit patients in the future.
Boulder, ColoradoAges 18 years+ - NCT05688176Recruiting
Testing blood RNA markers for esophagus cancer and Barrett’s
This study looks for helpful “RNA markers” found in blood to improve diagnosis in people with Barrett’s esophagus or esophageal cancer. It may help doctors spot disease more reliably, but it requires specific health and treatment conditions and a planned biopsy blood sample process.
Ghent, Oost-VlaanderenAges 18 years+ - NCT07797556Enrolling by invitation
Virtual reality headset as a monitor for medical procedures
This study tests whether using the Apple Vision Pro virtual reality headset as a monitor during medical procedures is safe and effective. It may help doctors see better during procedures, but you need to meet specific vision and health requirements.
Houston, TexasAges 18 years+ - NCT06534307Recruiting
Long-term follow-up for children from PETN studies
This study checks on the health and development of children whose mothers took part in the PETN studies. It involves questionnaires and a physical exam for kids aged 5 and older.
Tübingen, Baden-WurttembergAges 6–18 - NCT06543108Recruiting
Comparing two PET scans for stomach cancer
This study compares two types of PET scans (FAPI and FDG) to see which one works better for diagnosing stomach cancer. You would receive both scans within a week, and your doctor would also check your blood for tumor markers.
Changsha, HunanAges 18–90 - NCT05471232Recruiting
Genomic testing for youth mental health crises with IDD
This study looks at genetic (DNA) information to understand mental health crises in youth with intellectual and developmental disabilities. It may help doctors learn why these crises happen and improve how future families are supported.
San Diego, CaliforniaAges 7–17 - NCT06551805Recruiting
Ferumoxytol for better MRI images in atherosclerosis patients
This study tests whether a special iron-based contrast agent called ferumoxytol can improve MRI images of arteries affected by atherosclerosis. It may help doctors see blockages or inflammation more clearly.
Nanjing, JiangsuAges 18 years+ - NCT07776678Recruiting
Body fat and muscle measurement study

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 662 recruiting diagnostic 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 diagnostic 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 diagnostic 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.
