Recruiting studies
- NCT07272083Recruiting
New ways to check if liver cancer ablation worked
This study tests new criteria for evaluating how well thermal ablation (using heat to destroy cancer nodules) worked in people with hepatocellular carcinoma (HCC, a type of liver cancer). It aims to improve follow-up imaging with contrast-enhanced ultrasound (CEUS) or CT/MRI to see if the treatment was successful.
RomaAges 18 years+ - NCT07261228Recruiting
Comparing carbon footprint of diagnostic vs. therapeutic upper endoscopy
This study looks at how much carbon dioxide is released during upper endoscopy, comparing people having a diagnostic procedure for stomach discomfort versus those having treatment for a bleeding ulcer. It may help understand which type of procedure has a bigger environmental impact.
BangkokAges 20–80 - NCT06068361Recruiting
Better diagnosis of Lewy body dementia

Paris, FranceAges 55–85 - NCT06754995Recruiting
Testing a new nerve stimulation method for surgery
This trial tests a special nerve stimulation technique (100 Hz tetanic stimulation) to see if it can help monitor muscle function during anesthesia. It might help doctors make sure patients are properly relaxed during surgery.
Debrecen, Hajdú-BiharAges 18–65 - NCT04046796Recruiting
Study genetics in identical twin who differ in symptoms
This study looks at DNA changes to explain why two identical (monozygotic) twins can have different symptoms. It may help clarify the cause of an unclear condition in one twin so the right diagnosis (and future treatment) can be found.
TübingenAges Any age - NCT06111807Recruiting
Validating blood tests for stage III lung cancer
This trial is testing whether new blood tests can reliably detect and monitor stage III non-small cell lung cancer (NSCLC). It hopes to improve how doctors track your cancer and decide on treatment.
Nice, NiceAges 18 years+ - NCT07257796Recruiting
AI tool for finding early stomach changes
This trial tests if an artificial intelligence program can help doctors better detect certain pre-cancerous changes in the stomach lining during an advanced endoscopy procedure. It may benefit people at average risk who are already scheduled for this type of exam.
Jinan, ShandongAges 40–75 - NCT07253311Recruiting
Testing a rapid test for Candida auris
This trial is testing a rapid test to detect Candida auris, a hard-to-treat fungus. You can join if your doctor suspects you have this infection or you're being checked for it on your skin, and your lab sample is grown on specific plates or broths.
AthensAges 18 years+ - NCT04024774Recruiting
Genetic testing study for rare diseases with an unclear cause
This study looks for a genetic (DNA) explanation for rare diseases when usual genetic testing hasn’t found an answer. It may help by re-analyzing prior results and comparing them with parents’ DNA to better pinpoint the cause.
DijonAges Any age - NCT07246837Recruiting
Smarter antibiotic use for urinary tract infections in primary care
This trial tests a new way to check urine tests and prescribe antibiotics more carefully for adults with a suspected urinary tract infection (UTI). It aims to make sure you get the right treatment and avoid unnecessary antibiotics.
Houston, TexasAges 18 years+ - NCT07242014Recruiting
New PET scan for prostate cancer
This trial tests a new PET scan called XACP3 to see if it can find prostate cancer as well as the standard PSMA PET scan. You could help by having both scans to compare them.
Xiamen, FujianAges 18–80 - NCT07243249Recruiting
Quick virus test to guide antibiotic use
This study tests whether a quick test for COVID-19, flu, and RSV can help doctors avoid giving antibiotics when they aren't needed. It's for people with fever or chest infection symptoms who are not sick enough to be hospitalized.
GarchesAges 1 year+ - NCT07244094Recruiting
AI predicts breast cancer spread risk from tissue scans
This trial uses artificial intelligence to analyze images of your tumor tissue to predict if breast cancer might spread to other parts of the body. It may help doctors better understand your individual risk and guide treatment decisions.
Changchun, JilinAges 18–95 - NCT07248878Recruiting
Cervical cancer organoid study using biopsy samples
This trial aims to grow miniature versions of cervical cancer tumors (organoids) from biopsy tissue. It helps researchers learn more about the cancer and potentially find better treatments, without any extra procedures beyond your standard diagnostic biopsy.
Roma, RMAges 18 years+ - NCT06342206Recruiting
TCM Assessment for Recent Ischemic Stroke
This study uses traditional Chinese medicine (TCM) diagnostic tools to evaluate patients who had an ischemic stroke within the last 10 days. It aims to understand the acute and chronic phases of stroke to help guide future treatments.
ChanghuaAges 20 years+ - NCT06697093Recruiting
Polish registry for cardiogenic shock patients
This trial is a registry that collects information on diagnosis, treatment, and outcomes for people with cardiogenic shock (when the heart can't pump enough blood to the body). It may help doctors learn more about this condition and how to treat it better.
Wroclaw, Lower Silesian VoivodeshipAges 18 years+ - NCT06863324Recruiting
Impact of radiation sensitivity on late side effects of facial pain radiosurgery
This study looks at whether how sensitive people are to radiation affects late side effects after radiosurgery for trigeminal neuralgia. It may help doctors better predict and prevent long-term problems.
Nice, Alpes-maritimesAges 18 years+ - NCT07230964Recruiting
Heart valve study using a non-invasive skin test
This trial tests a special skin test (impedance cardiography) that may detect heart muscle changes in people with aortic stenosis. It could help doctors decide when valve replacement is needed.
Chicago, IllinoisAges 18 years+ - NCT07237984Recruiting
COCO study for colorectal cancer screening
This trial looks at substances in your body to help find colorectal cancer earlier. It is for people who are already scheduled for a colonoscopy, either because of a positive stool test or cancer symptoms.
HillerødAges 18 years+ - NCT07223489Recruiting
Understanding Adult SMA Diagnosis & Treatment Experiences
This trial explores the experiences of adults with spinal muscular atrophy (SMA) in the MedStar Health System, looking at how they are diagnosed and treated, and any differences in care they may face.
Washinton, District of ColumbiaAges 18 years+ - NCT07223827Recruiting
Testing a handheld nerve-signal device
This study is testing a small, handheld device that checks nerve signals at the bedside or in the clinic. It may help doctors quickly understand nerve problems without a big machine.
Indianapolis, IndianaAges 18 years+ - NCT07224906Recruiting
Observing patients having a right heart catheterization
This study observes people who are already scheduled for a right heart catheterization, a procedure that checks the pressure in your heart. It helps doctors learn more about heart conditions without adding any extra treatments or procedures.

PET scan for cancer spread in the abdomen
This trial tests a new PET/CT scan using a special tracer to detect cancer that has spread to the lining of the abdomen (peritoneal carcinomatosis) in people with colorectal, stomach, ovarian, or pancreatic cancer. It aims to see if this scan is better at finding the spread than standard imaging.

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 659 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.
