- NCT05841914Recruiting
Testing a lab test to diagnose eye lymphoma from fluid
This trial checks how well a molecular (DNA/RNA) lab test can diagnose vitreo-retinal lymphoma, using eye fluid collected during a medically needed procedure. If you have signs doctors suspect this condition, the test may help confirm the diagnosis more accurately.

Blood test for better stomach cancer diagnosis
This study is testing whether small molecules in your blood (called 'small non-coding RNAs') can help doctors more accurately diagnose stomach cancer. If you have recently been diagnosed, this study will look for those molecules to see if they can be used as a simple blood test in the future.
Nantong, JiangsuAges 18–85 - NCT06771102Recruiting
New single-use gastroscope compared to standard for bedside use
This trial tests a single-use gastroscope used at the bedside versus the standard reusable gastroscope used in the endoscopy unit. It aims to see if the bedside scope works as well for patients who are already in the hospital and need an upper endoscopy without general anesthesia.
KøgeAges 18 years+ - NCT06268795Recruiting
Comparing biopsy vs. aspiration for shoulder/elbow revision surgery
This study compares two methods—biopsy (taking a small tissue sample) and aspiration (drawing fluid)—to see which one better detects infection in people having repeat shoulder or elbow replacement surgery. The results will help doctors choose the best test for future patients.
Wigan, LancashireAges 18 years+ - NCT06755632Recruiting
Hepatic fibrosis or cirrhosis screening trial

KalisizoAges 15–39 - NCT06749145Enrolling by invitation
Using deep learning to find aortic stenosis earlier
This study tests if a deep learning tool can help detect aortic stenosis, a heart valve condition, in older adults during routine primary care visits. If you are 70 or older and have not had a recent echocardiogram, you may be able to join.
New Haven, ConnecticutAges 70 years+ - NCT06728930Enrolling by invitation
New test for diagnosing latent and active TB
This study tests a new type of lab test to find TB bacteria more accurately. It is for people who are being checked for latent (hidden) TB infection, or who have just been diagnosed with active TB. The goal is to see if the new test can help doctors diagnose TB better and faster.
LondonAges 18 years+ - NCT06738173Recruiting
Gut bacteria test to screen for colorectal cancer
This trial tests a new tool that looks at gut bacteria to help find colorectal cancer earlier. It's for people who already had a positive result on a standard stool test (FIT) as part of a national screening program.
Rome, RMAges 50–74 - NCT03580785Recruiting
Study of delayed tooth eruption in children and teens
This study looks at how doctors diagnose delayed tooth eruption and how that affects treatment. It focuses on people with a condition called Primary Failure of Eruption (PFE) and tries to refine the best diagnostic checks.
StrasbourgAges 6 years+ - NCT06726161RecruitingPhase 1/Phase 2
Targeted radiation therapy for advanced liver cancer
This trial tests a new way to find and treat liver cancer that cannot be removed by surgery. First, a special dye (RYZ811) is used to see if your cancer cells have a marker called GPC3. If they do, you may receive a targeted radiation treatment (RYZ801) that seeks out those cells. This trial is for people whose liver cancer has grown despite receiving at least one prior therapy.
Birmingham, AlabamaAges 18 years+ - NCT06720844Recruiting
Precocious puberty and related brain conditions study
This study looks at children with central precocious puberty (early puberty that starts in the brain) to see how often it's linked with other developmental issues. It compares how these children develop and respond to treatment.
Bologna, BolgonaAges Up to 18 years - NCT06708000Enrolling by invitationPhase 3
Personalized testing for new chest pain
This trial compares a personalized evaluation approach to standard care for people with new chest pain who might have heart disease. It aims to see if tailoring tests can improve diagnosis and outcomes.
HerningAges 30–75 - NCT06709872Recruiting
Study to tell borderline from early ovarian cancer
This study uses ultrasound and blood tests to help doctors tell the difference between a borderline ovarian tumor and an early-stage invasive ovarian cancer. If you have a cyst found on your ovary that might be one of these types, joining could help improve diagnosis.
Leuven, Flemish BrabantAges 18 years+ - NCT06686251Recruiting
AI assistant for reading chest X-rays in breathing problems
This study tests a computer program that helps doctors read chest X-rays faster and more accurately. It is for adults who had an X-ray because of breathing problems like a cough or fever.
Curitiba, ParanáAges 18 years+ - NCT06680830RecruitingPhase 2
Testing NEU-411 for early Parkinson's with LRRK2 gene change
This trial tests an experimental drug called NEU-411 for people with early Parkinson's disease who have a specific genetic change (LRRK2). It aims to see if the drug can slow the disease progression.
Sun City, ArizonaAges 40–80 - NCT06672302Recruiting
Blood test to find high breast cancer risk
This study uses a blood test to help identify women who are at high risk for breast cancer. It is for Korean women aged 40 or older who have a suspicious breast finding and need a biopsy.
Honolulu, HawaiiAges 40 years+ - NCT06653413Recruiting
Using dynamic chest x-ray to diagnose COPD
This study tests if a new type of chest x-ray (dynamic chest x-ray) can help diagnose COPD. You would breathe normally and deeply while the x-ray takes images for 20 seconds. This could be a more comfortable way to check for COPD compared to standard breathing tests.
Guangzhou, GuangdongAges 40–80 - NCT06649552Recruiting
French validation of a psychosis risk questionnaire for teens

LilleAges 12–17 - NCT06646237Recruiting
Using a blood test to diagnose TB in pleural fluid
This study tests a new blood test that looks for TB DNA to see if it can help diagnose tuberculosis in people who have fluid around one lung. If the test works, it might make diagnosing TB faster and less invasive.
Hong Kong, Hong KongAges 18 years+ - NCT06634654Recruiting

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.
