Recruiting studies
- NCT05676827Enrolling by invitation
Study pain and stress in people with long-term jaw muscle pain
This trial looks at how long-lasting jaw (masticatory) muscle pain relates to the nervous system and emotional stress. It may help researchers understand why symptoms persist and guide future treatments.
WroclawAges 18–80 - NCT05888974Recruiting
Test of heart ultrasound to guide fluids in shock
This study checks whether a specific heart ultrasound measurement can help doctors decide if you will benefit from extra fluid during early emergency treatment for shock. It may help avoid unnecessary fluids and support faster, safer decision-making.
NîmesAges 18 years+ - NCT05490901Recruiting
Test exercise heart pressure measurements with an ultrasound
This study looks at how well two heart tests taken during exercise—direct heart pressure measurement and an ultrasound—can explain shortness of breath with activity. It may help doctors better diagnose what’s causing your symptoms.
SeoulAges 19 years+ - NCT05133245Enrolling by invitation
Study of genes in people with PHACE syndrome
This study looks at genetic (DNA) differences in people who have PHACE syndrome. It also includes an eye exam, and results may help doctors better understand the condition.
Nashville, TennesseeAges Any age - NCT04707872Recruiting
Study of a blood test after heart transplant
This study checks whether a special blood test can help detect heart transplant rejection or problems by comparing it to biopsy results. It may help your care team monitor your transplant with less guesswork.
Little Rock, ArkansasAges Any age - NCT04832698Recruiting
Survey of radiology residents after endovascular simulator training
This study is a survey that asks current interventional and diagnostic radiology residents about their experience after training with an endovascular simulator. Your answers may help improve the simulator training program for future residents.
Houston, TexasAges 18 years+ - NCT04858217Recruiting
Testing blood and joint fluid tests for hip or knee infection
This trial checks how accurate certain blood tests and joint-fluid (synovial) tests are at identifying infections around hip or knee replacements. It also looks at whether these tests are worth the cost, to help doctors choose the best next step.
BolognaAges 18 years+ - NCT04313140Recruiting
MRI virtual biopsy to predict glioma grade
This study uses special MRI images to estimate the “grade” of a suspected brain tumor (glioma) without taking a tissue sample first. If it works well, it may help doctors better plan care based on imaging.
PoitiersAges 18 years+ - NCT04837339Recruiting
Testing markers to predict problems after lung transplant
This study looks for lab “clues” that can help predict how well someone’s lungs will do after a lung transplant. It may help doctors spot transplant-related problems earlier so care can be planned sooner.
SuresnesAges 15 years+ - NCT04731857Recruiting
Genetic testing results study for rare diseases
This study looks at how well different genetic tests (whole exome/genome sequencing and standard genetic tests) work for diagnosing rare genetic diseases and inherited cancer conditions. It may help confirm which testing approach provides the clearest results for families.
TübingenAges Any age - NCT04218617RecruitingPhase 2
One vs two radiation treatments for spine metastases
This trial tests whether giving radiation to a spine metastasis in one dose works as well as giving it in two smaller doses. It aims to control tumors while keeping side effects and risk to the spinal cord low.
Cleveland, OhioAges 18 years+ - NCT04523701RecruitingPhase 3
Testing a “white test” to find bile ducts during liver surgery
This trial studies whether a simple “white test” using a special lipid (fat-like) solution can help the surgical team spot open bile ducts early during liver removal. Finding them sooner may help prevent bile leakage after liver surgery.
AarauAges 18 years+ - 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 - NCT02812290Recruiting
Microarray testing during lung transplant biopsy
This study looks at using a special lab test (microarrays) on tissue taken during a lung transplant biopsy. It aims to learn how the test may help doctors better diagnose and guide care after transplant.
Phoenix, ArizonaAges 18 years+ - 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+ - NCT03746210Recruiting
Testing a painless scan to study liver spots in cirrhosis
This trial studies “focal liver lesions,” meaning specific spots in the liver, using a non-invasive (no surgery or biopsy) approach. It may help doctors better understand what these spots are in people who have cirrhosis.
BonnAges 18–99 - NCT07166432Recruiting
New brain stimulation for thinking and balance problems in Cushing syndrome
This trial tests a new, minimally invasive brain stimulation technique for people with Cushing syndrome who have developed a condition called cerebellar cognitive affective syndrome (CCAS). It aims to improve both thinking skills and movement coordination.
BeijingAges 18–85 - NCT03681964Recruiting
Check tests for suspected Sjögren’s syndrome
This study follows people who have signs that might mean Sjögren’s syndrome and looks at how well a standardized work-up identifies the condition. It may help doctors confirm the diagnosis earlier and more consistently.
BrestAges 18 years+ - NCT02670408Recruiting
Microarrays test in heart transplant care
This study checks how special lab tests on heart tissue samples can help guide diagnosis and treatment for people with a heart transplant. You may be eligible if you already need a heart tissue biopsy for a clinical reason and can provide consent.
Los Angeles, CaliforniaAges 18 years+ - NCT06464432Recruiting
Complex PTSD treatment test for Egyptians in cities
This study is testing a therapy for Complex PTSD that has been adapted to fit Egyptian culture. It aims to see if the treatment helps people with severe trauma and provides a better way to diagnose the condition in Egypt.
CairoAges 18 years+ - NCT04737317Recruiting
Check criteria to diagnose cardiac sarcoidosis
This study tests how doctors can best tell whether someone has cardiac sarcoidosis, a condition where inflammation affects the heart. It may help you get a more accurate diagnosis using expert guidelines and special heart tests, and it groups patients as proven, probable, or unlikely.
LeipzigAges 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+ - NCT06839833Recruiting
APOL1 gene test study for trial volunteers
This study checks if a new genetic test for the APOL1 gene works correctly. It uses samples from people who have already joined another drug trial.
Durham, North CarolinaAges 18–70 - NCT04451265Recruiting
MRI test study for suspected anterior optic nerve stroke
This study checks how well a special MRI scan (diffusion-weighted imaging) can identify a specific optic nerve problem called anterior ischemic optic neuropathy (when blood flow to the optic nerve is reduced). If you have symptoms that suggest this condition, the trial compares your MRI findings to doctors’ assessment to see if the scan helps confirm the diagnosis.

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.
