Simple blood test for colorectal cancer screening
This study is testing a new blood test (Signal-C) to see if it can help find colorectal cancer early. You may be able to join if you are average risk and getting a routine screening colonoscopy.
Raonoke, VirginiaAges 45–84 - NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.
Chula Vista, CaliforniaAges 45–84 - NCT06066372Recruiting
Using computer models to reduce need for scans for bile duct stones
This trial tests if a computer model can accurately predict when someone has a stone in the bile duct, so fewer people need invasive scans like endoscopic ultrasound or MRCP. It may help avoid unnecessary procedures in patients with a medium chance of having a bile duct stone.
Hyderabad, TelanganaAges 18–80 - NCT06079970Recruiting
Testing a microscope during lung biopsy
This trial tests if a special microscope (confocal laser endomicroscopy) used during a bronchoscopy can help doctors see and diagnose suspicious lung spots more clearly. It may help you if you have a small-to-medium sized spot in your lung that needs a biopsy.
New York, New YorkAges 18 years+ - NCT04526587Recruiting
Study of breast cancer markers after CDK4/6 inhibitor treatment
This study looks at lab markers and clinical features in people with certain types of breast cancer who are being treated with, or have already been treated with a CDK4/6 inhibitor like abemaciclib (ciclib-based therapy). It aims to understand patterns that may help doctors better characterize breast cancer after these treatments.
Buffalo, New YorkAges 18 years+ - NCT06045416Recruiting
Borrelia (Lyme) blood test study
This trial is testing a new blood test to help diagnose Lyme disease (borrelia infection) in children. If you are at the emergency room with symptoms that might be Lyme disease and you have a healthy immune system, you might be able to join.
ZurichAges 1 month–17 years - NCT06013423RecruitingPhase 2
Cord blood transplant with chemo and radiation for high-risk blood cancers
This trial tests a cord blood transplant after a reduced-intensity chemotherapy and radiation regimen for patients with high-risk blood cancers like leukemia, lymphoma, or MDS. The goal is to see if this approach can help destroy cancer cells and restore healthy blood cells.
Seattle, WashingtonAges 6 months–65 years - NCT06018831Recruiting
Kidney screening for newborns
This study offers free urine and ultrasound screening for kidney disease in all newborn infants, with a goal to find and track potential issues early over the first 3 years of life.
Nantong, JiangsuAges Up to 6 years - NCT05996731Recruiting
Using RNA tests to help diagnose rare genetic diseases
This study uses RNA sequencing to find genetic causes of rare diseases that standard DNA tests might miss. It may help people who have symptoms of a rare disease but no clear genetic diagnosis yet.
Ranica, BGAges Any age - NCT05948904Recruiting
Cryogenic catheters tested in donated lung tissue
This study tests a technique using a special cold (cryogenic) catheter to collect samples (biopsy) and destroy abnormal lung tissue (ablation) in lungs outside the body. It’s aimed at improving how pulmonary (lung) lesions could be diagnosed and treated in the future.
Montreal, QuebecAges 18 years+ - NCT05965999Recruiting
Registry study for esophageal precancer screening
This study collects information from people who are already being screened for Barrett's esophagus or esophageal cancer using the EsoCheck and EsoGuard tests. It helps doctors learn more about how well these tests work in real life.
Lake Forest, CaliforniaAges Any age - NCT05919160Enrolling by invitation
New tiny electrode to record brain activity during DBS
This study tests a high-density microelectrode that captures detailed brain recordings while surgeons place a deep brain stimulator for Parkinson’s disease. It may help doctors better locate the exact brain area to target during surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT05941052Recruiting
Testing new at-home TB checks in the clinic
This study tests new tools that can check for tuberculosis (TB) more quickly at or near where care happens. It includes people with cough or TB risk factors, and also the health workers who perform TB testing, to see how well the tests work and how easy they are to use.

Home sleep testing after starting noninvasive breathing support
This study checks breathing/sleep measurements done at home for people who recently started a machine that helps them breathe without an endotracheal tube. It may help the team confirm how well home monitoring works after hospital setup of this breathing support.

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.
