Recruiting studies
- NCT05963841Recruiting
Testing AI to improve parathyroid scan imaging
This study uses past and future parathyroid scan data to train and test an AI tool. The goal is to improve how the scans are interpreted using nuclear medicine imaging from a specific scanning process.
BesançonAges 18 years+ - NCT05985668Recruiting

How cues affect drinking and smoking habits
This study looks at how certain cues (like seeing a drink or a cigarette) trigger cravings and behavior in people who drink alcohol or smoke. Understanding this may help improve addiction treatments.
BerlinAges 16–65 - 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 - NCT06007261Recruiting
Testing a new microscope for lung cancer diagnosis
This study tests a new microscope that quickly analyzes lung tissue during a bronchoscopy or surgery. It may help doctors make faster, more accurate decisions about your care.
Nijmegen, GelderlandAges 18 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 - NCT06028646Recruiting
Using CT scans to diagnose airway collapse in children
This trial tests if a special CT scan can help diagnose tracheomalacia (a condition where the airway collapses during breathing) in children who have already had a bronchoscopy.
New York, New YorkAges birth–18 years - NCT06038864Recruiting
New screening tool for leg lymphedema
This study is testing a new tool to help doctors screen, diagnose, and track leg swelling (lymphedema). It involves two groups: people starting intensive treatment and people who are already on maintenance therapy.
LeuvenAges 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 - NCT06059963Recruiting
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 - 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 - NCT06068361Recruiting
Better diagnosis of Lewy body dementia
This study uses a combination of tests to improve diagnosis of dementia with Lewy bodies compared to Alzheimer's disease and healthy aging. You may help doctors identify the right diagnosis more accurately.
Paris, FranceAges 55–85 - NCT06074731Recruiting
Eye imaging study using a new scanner
This trial uses a special eye scanner to look at eye diseases. It might help doctors see eye problems more clearly.
Linz, Upper AustriaAges 5–110 - 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+ - NCT06083636Recruiting
Better lab tests for people with hypothyroidism on levothyroxine
This study aims to improve lab tests for people with hypothyroidism who take levothyroxine. It compares their test results to healthy volunteers to see if doctors can make more accurate diagnoses.
Amsterdam, North HollandAges 18–100 - NCT06083467Recruiting
Brain imaging study for Parkinson's and related disorders
This study uses brain imaging and tests to better understand Parkinson's disease and related conditions. It aims to improve diagnosis by comparing scans across different groups of people.
Philadelphia, PennsylvaniaAges 40–85 - NCT06092008Recruiting
New pneumonia tests for adults 65 and older
This study tests new ways to diagnose pneumonia faster and more accurately in older adults who come to the emergency room with breathing problems. The goal is to see if these new tests work better than the current methods.
Columbus, OhioAges 65 years+ - NCT06094660Recruiting
Nerve blocking for knee arthritis pain
This study tests two treatments for knee arthritis pain when knee replacement isn't an option: a nerve block using heat (radiofrequency ablation) or a chemical injection (phenol), compared to standard care. It aims to find a better way to reduce pain and improve daily function.
Hoorn, North HollandAges 35–90 - NCT06097195Recruiting
EEG test to help diagnose epilepsy after a first seizure
This trial studies a new way of analyzing EEG results to help doctors decide if a first suspected seizure was caused by epilepsy. If you had a first seizure and your EEG did not show clear signs of epilepsy, this test might improve your diagnosis.
TruroAges 18 years+ - NCT06101862Recruiting
CT scan vs. angiogram for certain heart attacks
This trial compares two ways to look at heart arteries: a CT scan (noninvasive) versus a traditional angiogram (a tube put into an artery). The goal is to see which is better for people having a certain type of heart attack.
Copenhagen, HellerupAges Any age - NCT06111105Recruiting
Comparing blood tests to guide colon cancer treatment
This study compares different blood tests to find the best way to detect tiny bits of cancer DNA after surgery for stage III colorectal cancer. It aims to help doctors decide if additional chemotherapy is needed to prevent the cancer from coming back.
Graz, StyriaAges 18 years+ - NCT06111417Recruiting
Rapid BRCA1/2 test for newly diagnosed breast cancer patients
This study tests a new ultra-rapid genetic test for BRCA1/2 mutations in people recently diagnosed with breast cancer. It aims to see if the faster result helps doctors and patients make treatment decisions sooner.

Common questions
- Are there clinical trials for diagnostic?
- Yes. Clin2 currently lists 675 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.
