Recruiting studies
- NCT06958731Enrolling by invitation
Comparing two ways to place a jugular vein catheter
This trial tests two ultrasound-guided methods for placing a catheter in the internal jugular vein in the neck. It aims to find which approach is safer and easier for patients needing this procedure.
Changchun, JilinAges 18 years+ - NCT06944353Enrolling by invitation
Fatty liver risk screening in the emergency department
This study looks at fatty liver findings on emergency department scans. If you have fatty liver and were sent home from the ED, the study may help connect you to follow-up care and avoid future liver problems.
Chicago, IllinoisAges 18 years+ - NCT06944314Enrolling by invitation
Doctors' views on pain during flexible cystoscopy with local anesthetic
This trial asks doctors to rate how much pain they think male patients feel during a minimally invasive bladder exam. It aims to see if doctors' estimates of pain are accurate.
Istanbul, IstanbulAges 18 years+ - NCT06900023Enrolling by invitation
Studying better ways to find breast swelling after cancer treatment
This trial looks at new tools to detect lymphedema (breast or arm swelling) after breast cancer treatment. If you had breast-conserving surgery, radiation, and have finished active therapy (except certain hormone treatments), researchers want to see if a simple device can spot fluid buildup early.
Boston, MassachusettsAges 18 years+ - NCT06843083Enrolling by invitation
Which advanced breast scan is better for you?
This study compares two advanced breast imaging methods—contrast-enhanced mammography (CEM) and breast MRI—to see which is better at finding cancer, especially in women with dense breasts or unclear mammogram results. If you are being referred for one of these exams, you may be able to join and help doctors learn which test works best.
NaplesAges 18 years+ - NCT06837064Enrolling by invitation
Can a chatbot help manage Irritable Bowel Syndrome?
This study tests whether a chatbot can help adults with Irritable Bowel Syndrome (IBS) manage their symptoms. If you have been diagnosed with IBS, you may be able to join and use the chatbot as part of your care.
MoscowAges 18 years+ - NCT06835244Enrolling by invitation
Study of PSMA PET/CT scans for non-prostate cancers
This study looks at how well a special scan (PSMA PET/CT) works for people with cancers other than prostate cancer. If your doctor already scheduled this scan for your care, you may be able to help researchers learn more about its accuracy.
BolognaAges 18 years+ - NCT06776835Enrolling by invitation
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 - 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+ - 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 - NCT06305039Enrolling by invitation
Better hearing with two cochlear implants
This study tests how well people with two cochlear implants (or one cochlear implant and one hearing ear) can hear in complex, noisy settings. It aims to improve how these devices help in everyday listening situations.
Bethesda, MarylandAges 18–85 - 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+ - NCT05214742Enrolling by invitation
Using stem cells to study rare growth disorders
This study looks at rare growth conditions (Silver-Russell, Beckwith-Wiedemann, and Temple syndrome) by creating lab cell models from patient information. It aims to help researchers better understand why these disorders happen and how they work.
ParisAges 3 months+ - NCT04987840Enrolling by invitation
Hospital program to reduce unnecessary lung culture tests in kids
This trial studies a hospital quality-improvement program that aims to use fewer “respiratory culture” tests in pediatric intensive care units (PICUs). It may help reduce unnecessary testing while maintaining good care for critically ill children.
Baltimore, MarylandAges Any age - NCT04726306Enrolling by invitation
Compare two scoring systems for hyperbaric care quality
This study compares two different ways to rate how well hyperbaric (pressure-based) medical care is being done. It aims to find which scoring method is more accurate and consistent.
Sleepy Hollow, New YorkAges Any age - NCT04607369Enrolling by invitation
Test using an app to map eye vision blind spots
This trial tests how well an EyeCTester smartphone app can measure vision blind spots and distorted vision compared with standard eye tests. If you qualify, you’ll do short near-vision and “Amsler grid” style tasks in the clinic to help confirm the app is accurate.
Bellaire, TexasAges 18 years+ - NCT03648359Enrolling by invitation
MRI scans to monitor low-risk prostate cancer in active surveillance
This trial uses special MRI scans to help track low-risk prostate cancer while you stay on active surveillance (meaning no immediate treatment). It may help your care team better understand changes in the cancer over time.
HerlevAges 18–75 - NCT03385876Enrolling by invitation
Rapid whole genome sequencing for children with suspected genetic illness
This study quickly reads a child’s DNA using whole genome sequencing to look for genetic causes of symptoms. It may help families and doctors better understand an underlying genetic condition and guide medical care.
San Diego, CaliforniaAges Any age - NCT03369353Enrolling by invitation
Personalized immune testing study for bowel and transplant patients
This study looks at whether a precise lab test can help understand inflammatory bowel disease, functional gut disorders, and immune changes after stem cell transplant or cell therapy. It may help doctors choose better monitoring and treatments based on your immune and gut test results.
Boston, MassachusettsAges Any age - NCT03319446Enrolling by invitation
Sharing anonymous samples for a diagnostic test
This trial collects and stores anonymous samples from consenting adults. It helps researchers evaluate or improve diagnostic testing without using your personal identity.
Salt Lake City, UtahAges 18–99

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 669 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.
