Recruiting studies
- NCT05229341Recruiting
Testing DNA “methylation” to evaluate thyroid nodule samples
This study looks at patient tissue from needle biopsies to see if DNA “methylation” patterns can help diagnose and guide treatment for thyroid nodules. You might benefit by helping improve how these nodules are evaluated, using information from your biopsy sample and medical data.

Testing a gut-based IgE blood test for food allergy
This study looks at whether a specific immune signal (IgE) found in the gut lining can help diagnose food allergy or food-related hypersensitivity. You may join if you have symptoms that suggest a food allergy, or (if you’re healthy) if you need endoscopy for other reasons.
ErlangenAges 18 years+ - NCT05266872Recruiting
Earlier diagnosis and better treatment study for Parkinson’s
This study is looking to improve how Parkinson’s and related brain conditions are identified and treated sooner. You may be asked to share your health information and provide blood or other samples, and possibly have procedures like a spinal fluid test or a small skin sample.
LuxembourgAges 18 years+ - NCT05312983Recruiting
Testing new hearing tests to better diagnose age-related hearing loss
This study is developing a set of hearing tests to more precisely identify age-related hearing loss. It may help you (or the study team) better understand what type of hearing problem you have and how to guide next steps.
ParisAges 18 years+ - NCT05339451Recruiting
Blood and tissue tests to improve endometriosis diagnosis
This study collects blood and small tissue samples during planned gynecological surgery to better diagnose endometriosis and predict its course. It may help future patients by making diagnoses and outlook more accurate.
Stockholm, HuddingeAges 18–45 - NCT05340023Recruiting
Test using lung scan patterns to diagnose a heart-lung condition
This study looks at patterns from specialized lung scan tests to help diagnose chronic thromboembolic pulmonary hypertension (a long-term problem with blood flow in the lungs after blood clots). If your results suggest this condition and you need a procedure to check heart pressure, you may be asked to join so the researchers can improve diagnosis.
Saint-EtienneAges 18 years+ - NCT05346757Recruiting
Test stool DNA changes to screen or find colorectal cancer
This study checks whether a stool test that looks for tiny genetic signals can help detect colorectal cancer (or find it again after prior findings). You may be asked to provide a stool sample around the time you get a colonoscopy.
BarcelonaAges 18–80 - NCT05364294Recruiting
Molecular testing for rare inflammatory (autoinflammatory) diseases
This study uses lab testing to better identify the cause of certain rare inflammatory conditions that happen without infection. Finding the cause may help doctors choose more targeted care for you or your child.
ParisAges 1 week–120 years - NCT05369546Recruiting
Imaging study for suspicious breast findings
This study looks at how detailed breast imaging can help diagnose breast cancer when a mammogram is suspicious. If your mammogram result was “highly suspicious” and you have not had a biopsy yet, the trial may be able to use your images to improve future diagnosis.
Tampa, FloridaAges 20–85 - NCT05372484Recruiting
Test technology to improve cervical cancer screening and diagnosis
This study tests a new technology to help find cervical cancer earlier by focusing on people who already had an abnormal screening result. It may help improve how abnormal tests are checked and diagnosed.
Houston, TexasAges 25–49 - NCT05385315Recruiting
Blood test study to help detect Parkinson’s disease early
This study looks for a new blood marker that could help doctors detect Parkinson’s disease earlier. Depending on your diagnosis and treatment status, your blood may be compared with other people’s to see how well the test works.
GrenobleAges 18 years+ - NCT05397392Recruiting
Diagnosis and treatment plan for heart–kidney problems
This study looks at the best way to diagnose and treat different types of heart-and-kidney problems that happen together. It may help you (or your caregiver) get the right classification and treatment approach based on how your heart and kidneys are affected.
NanjingAges 18 years+ - NCT05423665Recruiting
Ultrasound check to spot early growth problems in twin pregnancies
This study uses a special ultrasound method (speckle tracking echocardiography) to look for early signs that a twin pregnancy may have impaired fetal growth. It may help clinicians detect problems earlier and better understand how twin babies’ hearts and growth are affected.
GhentAges 18–45 - NCT05426135Recruiting
AI tool to assess cancer risk and guide care
This study tests an artificial intelligence (AI) system that uses your health information and medical images to better judge cancer risk and support diagnosis and treatment decisions. It may help doctors make more consistent assessments by combining clinical records, imaging, and other lab-style data.
Wuhan, HubeiAges 18–75 - NCT05432336Recruiting
Testing better lab diagnosis for serious eye infections
This study looks at how doctors collect and test eye infection samples to get more accurate results, especially in serious cases like corneal abscess or deep eye infection. If you have signs of a complex eye infection and a sample is needed, this trial may help improve the way diagnosis is done for patients like you.
Paris, IDFAges 18 years+ - NCT05432739Recruiting
Test a lung nodule blood/scan marker to find early cancer
This study looks at whether a new test can better identify early lung cancer in people who are being watched for an incidental lung nodule. It may help doctors decide which nodules need closer follow-up or treatment.
Goodmayes, EssexAges 18 years+ - NCT05439330Recruiting
Dental MRI to help diagnose jaw, gum, and tooth problems
This study tests whether a special dental MRI can give useful pictures to diagnose jaw joint problems, tooth-related tissue changes, and gum/inflammation issues, and to help plan some dental implant treatments. If you need imaging for these reasons, the trial may help doctors choose the best next treatment by using clearer, dedicated scans.
AarhusAges 18 years+ - NCT05445544Recruiting
Study of belly and baby microbes to improve preeclampsia screening
This study looks at tiny living organisms in pregnancy (and related body samples) to find better ways to screen for preeclampsia. By learning early warning signs, it may help doctors identify risk sooner during routine prenatal care.
Guangzhou, GuangdongAges 18 years+ - NCT05472493RecruitingPhase 2
Imaging test to help identify aldosteronism subtype in high blood pressure
This Phase 2 study uses a nuclear imaging scan to help doctors sort out which subtype of primary aldosteronism you may have. It may help confirm the right cause and guide more targeted treatment decisions.
Calgary, AlbertaAges 18 years+ - NCT05473520RecruitingPhase 3
Doxycycline add-on therapy for lung improvement in tuberculosis
This Phase 3 trial tests whether adding doxycycline to standard TB medicine can improve lung function and reduce lung tissue damage. It aims to see if patients recover better by targeting the lung response to TB.
Kota Kinabalu, SabahAges 21 years+ - NCT05505500Recruiting
Parent and patient interviews for childhood kidney swelling
This study uses interviews to understand how swelling from nephrotic syndrome affects daily life for children and their caregivers. It may help researchers design better care by capturing the patient and parent perspective.
Ann Arbor, MichiganAges 2 years+ - NCT05540561Recruiting
Testing and monitoring for nitrous oxide use
This study looks at how nitrous oxide (also called laughing gas) is detected and how health effects may show up over time. It may help doctors better diagnose problems early and track changes after use.

Common questions
- Are there clinical trials for diagnosis?
- Yes. Clin2 currently lists 929 recruiting diagnosis 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 diagnosis 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 diagnosis 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.
