Recruiting studies
- NCT04698421Recruiting
Blood and tissue sample collection for rare autoimmune nerve diseases
This study collects biological samples (like blood or other specimens) from people with rare neurological conditions that may involve the immune system. Your samples may help researchers better understand these diseases.
ToulouseAges 6–99 - NCT05127980Recruiting
Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues. You might be offered a chance to help doctors understand why some people get longer or more intense symptoms from infectious mononucleosis.
BaselAges 18 years+ - NCT01763125Recruiting
Tumor bank trial for storing your blood sample
This study sets up a “tumor bank,” which means storing and later using your blood sample for future cancer research (or inflammatory disease research). You may be able to join if you currently have exactly one diagnosis—either a cancer or an inflammation condition.
InnsbruckAges 18 years+ - NCT05410977Recruiting
Testing blood and stool for colon cancer in Lynch syndrome
This study collects blood and stool samples to see how well they can detect colorectal cancer or advanced growths in people with Lynch syndrome (an inherited colon cancer risk) or suspected Lynch syndrome. It may help find cancer or precancer earlier, which can improve next-step decisions.
Scottsdale, ArizonaAges 18 years+ - NCT05663502Recruiting
Donate blood and tissue samples for HIV-related cancer research
This study collects blood and tissue samples to help researchers learn more about cancers related to HIV/AIDS. You may be able to join if you’re 18+ and have HIV and a cancer diagnosis, or (if HIV-negative) a certain cancer that is closely linked to AIDS-related cancers.
La Jolla, CaliforniaAges 18 years+ - NCT05805566Recruiting
Study of care for long COVID symptoms in adults
This study follows people who enter a specialized care pathway for long COVID (post-COVID syndrome) to better understand symptoms, needs, and outcomes. It may help improve how multidisciplinary care is organized for long COVID over time.
Pierre-BéniteAges 18 years+ - NCT03420118Recruiting
Study of tumor and blood markers in gynecologic cancers
This study looks at tumor tissue and blood samples to find biological “markers” in people with gynecologic cancers. It may help researchers understand disease better and could guide future, more personalized treatments.
Toronto, OntarioAges 18 years+ - NCT04088422Recruiting
Blood test DNA study in mature B-cell lymphoma
This study looks at “cell-free DNA,” meaning tiny bits of DNA found in blood, in people with mature B-cell lymphoma. It may help doctors understand the disease better and how blood tests could be used to monitor it.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT03636464Recruiting
Antibiotic testing in people on kidney dialysis
This trial studies how common antibiotics move through the body when someone is on kidney replacement therapy (dialysis), including when dialysis starts during treatment. The results may help doctors choose the right antibiotic dose and timing for better infection treatment.
Abu DhabiAges 18 years+ - NCT02382601Recruiting
Study of pregnancies with slow fetal growth
This study follows pregnancies where the baby appears smaller than expected on ultrasound. It may help researchers better understand why this happens and how to monitor care over time.
Aurora, ColoradoAges 18–45 - NCT05428267Recruiting
Sexual function study for people with cirrhosis
This study looks at sexual dysfunction in people who have cirrhosis (scarring of the liver). It may help researchers understand causes and better care for sexual problems in this condition.
ParisAges 18 years+ - NCT06680843Recruiting
Immune signatures from animal virus exposure in Cambodia
This study aims to understand how people's immune systems respond to viruses that spread from animals to humans (zoonotic viruses). If you have had recent contact with potentially infected animals in Cambodia, your participation can help researchers find ways to detect and prevent future outbreaks.
BattambangAges 18–65 - NCT06709976Enrolling by invitation
Fertility test and IVF study
This study looks at whether a special test called ReceptIVFity, which checks the health of the vagina, can help improve pregnancy rates in women undergoing IVF or ICSI. If you are planning IVF or ICSI and are of European origin, you might be able to join.
Rotterdam, South HollandAges 18–42 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT07715682Recruiting
Gentle touch and calm for premature babies' blood tests
This study tests whether gentle human touch and fewer distractions can help reduce pain and improve comfort for premature babies during a standard heel-prick blood test.
AnkaraAges 7 months–9 months - NCT07707245Recruiting
Finding biomarkers in lung disease and lung cancer
This trial studies blood and tissue samples from people with COPD, IPF, or lung cancer to find markers that can help diagnose and predict these conditions. It aims to discover why some lung diseases progress to cancer.
Milan, MilanAges 18 years+ - NCT03025074Recruiting
Blood sample bank for liver disease research
This study collects blood samples to build a “biobank” (a stored library of samples) for researchers studying liver diseases like hepatitis, fatty liver disease, and liver cancer. It may help future testing and treatments by allowing scientists to study patterns in people with and without liver conditions.
Buffalo, New YorkAges 7 years+ - NCT03323216Recruiting
Testing heart-related blood markers in people with diabetes and heart failure
This study looks for blood markers that may help explain or predict heart problems in people who have type 2 diabetes and heart failure. To join, you may also need to be having a planned heart procedure where doctors can collect study information.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT03648918Recruiting
Study family genetics in type 1 diabetes
This study looks at genetic patterns in families where someone has type 1 diabetes (an autoimmune condition). It may help researchers understand why type 1 diabetes happens and who is at risk.
Milwaukee, WisconsinAges 2 years+ - NCT03830320RecruitingPhase 1
PET scan to look for blood clots in the heart or lungs
This Phase 1 study uses a PET scan to detect blood clots (thrombosis) in specific groups of people. It’s testing how well the scan can find clots and how it should be timed with other heart or illness tests.
Boston, MassachusettsAges 18–85 - NCT04513054Recruiting
Genetic study for stress-related heart muscle weakness
This study looks for a possible inherited (genetic) reason some people develop Takotsubo cardiomyopathy after severe stress. If you’ve had this condition, the study may help explain why it happens and whether families could be at higher risk.
Aberdeen, AberdeenshireAges Any age - NCT05010863Recruiting
Test and develop a stomach cancer detection kit
This study looks for marker signals from stomach cancer tissue to improve a detection kit. You may be asked to provide tissue samples, especially if you have a new stomach cancer diagnosis and have not had anti-cancer treatment yet.

Diver screening to spot risk for lung fluid after diving
This study checks whether certain personal factors can predict who may get “immersion pulmonary edema,” a condition where fluid builds up in the lungs after water exposure and diving. If you’re a diver, your results may help tailor safety steps and reduce risk.
ToulonAges 18–60 - NCT05263297Recruiting

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 348 recruiting studies that include Blood collection, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Blood collection trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Blood collection an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Blood collection or a specific trial is right for you.
