Recruiting studies
- 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 - 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+ - 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+ - NCT02732171Recruiting
Blood and bone marrow tests to track breast cancer return
This trial checks whether specific “surveillance” markers (measured from blood and bone marrow) can help predict if breast cancer comes back after standard treatments. It may help doctors monitor you more accurately and earlier if recurrence risk is high.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02735824Recruiting
Genetic study of immune problems in children
This study looks for new genetic causes of immune system conditions that can run in families. If you join, researchers will collect health information (and usually samples) from children with immune concerns and from close relatives for comparison.
Zurich, Canton of ZurichAges Any age - 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 - NCT01173341Enrolling by invitation
Checking heart side effects of breast cancer treatments
This study looks at how breast cancer medicines affect the heart. It may help doctors better prevent, spot early, and manage heart side effects from trastuzumab and/or anthracycline chemotherapy.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05014165Recruiting
Cord blood study for leukemia with stored birth samples
This study looks at leukemia “genetic clues” using special stored samples, including cord blood saved at birth. It may help researchers better understand leukemia biology and how common mutations may show up early.
Minneapolis, MinnesotaAges Up to 25 years - NCT04970472Recruiting
Urothelial bladder cancer sample collection for adults
This trial collects clinical samples from adults who have suspected or confirmed urothelial (bladder/urinary tract lining) cancer. It helps researchers study the disease and may support future improvements in diagnosis or treatment.
ToulouseAges 18–99 - NCT06661564Recruiting
Testing tears for Alzheimer's disease diagnosis
This study looks at whether tears can help detect Alzheimer's disease. You will have your tears collected and tested for possible biomarkers.
Tours, FranceAges 18 years+ - NCT02168868Recruiting
Blood tests to find autism-related protein signals
This study looks at blood samples from children (and sometimes parents) to see if certain protein patterns can help identify or better understand autism spectrum disorder. The results could support finding “biomarkers,” which are measurable signs that may guide future research or care.
JerusalemAges 10 months–19 years - NCT07054346RecruitingPhase 1
Radioactive drugs before prostate surgery for high-risk prostate cancer
This trial compares two radioactive drugs (177Lu-PSMA-617 and 225Ac-PSMA-617) given before prostate removal surgery in men with high-risk prostate cancer that has not spread far. The goal is to see which drug is better at shrinking the tumor and reducing the chance of cancer coming back.
San Francisco, CaliforniaAges 18 years+ - NCT02478892Recruiting
Screening study for pancreatic cancer in inherited gene risk
This trial tests ways to screen people who have a family-passed (inherited) gene mutation linked to higher pancreatic cancer risk. The goal is to find pancreatic cancer earlier and improve how screening is done for people at increased risk.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07075601Recruiting
Study of bacteria on heart valves during cardiac surgery
This study looks at the types of bacteria living on heart valves removed during surgery. Researchers want to learn more about these bacteria to better understand heart valve health and infections.
Toulouse, FranceAges 18 years+ - NCT06810635Recruiting
Polyphenol types in people with type 2 diabetes
This study looks at how different people process polyphenols (natural compounds in plant foods) based on their gut bacteria. It compares people with type 2 diabetes to those without diabetes to learn about possible health benefits.
Ghent, East FlandersAges 40–85 - NCT07796672Recruiting
Blood test study for cervical cancer biomarkers
This study is looking for markers in the blood of people with cervical cancer that might help doctors choose the best treatment. It is a feasibility study, meaning it aims to find out if this approach works before a larger trial.
Brisbane, QueenslandAges 18 years+ - NCT05263804Recruiting
Study uses MRI and blood clues after ischemic stroke
This study looks for biological and imaging markers that may predict heart/vascular outcomes after an ischemic stroke. You may join if you are eligible for standard stroke treatment and can complete planned follow-up and MRI scans.
BronAges 18 years+ - NCT02861781Recruiting
Collecting body tissue samples during bariatric surgery
This study collects small tissue samples during planned weight-loss surgery to better understand metabolism and how insulin works in people with and without type 2 diabetes. You may help researchers by allowing their team to take these samples while you are already having surgery.
MontpellierAges 18–65 - NCT07755007Recruiting
Blood sample tube transport comparison
This trial compares two ways of sending blood samples from an emergency room to the lab: quickly through a tube system or carried by staff. It checks if either method breaks red blood cells, which can affect test results, to see if the tube system is safe to use.
Istanbul, PendikAges 18 years+ - NCT05568966Recruiting
Blood sample collection for new diagnostic tests
This study collects small blood samples to help test and improve new diagnostic devices. You may be eligible if you’re an adult with certain symptoms that match one of several health “groups,” and if you can consent and read English.
Airdrie, ScotlandAges 18 years+ - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 years+ - NCT07455136Recruiting
Blood test for traumatic brain injury diagnosis and monitoring
This study is testing a new blood-based test to help doctors diagnose traumatic brain injury (TBI) and track recovery or complications. If you have had a head injury and a CT scan as part of your care, you may be able to join.
Sacramento, CaliforniaAges 18 years+ - NCT07435467Recruiting
Blood tests for brain health in older hospital patients
This trial looks at how blood biomarkers relate to thinking, daily function, and survival in older adults, including those with neurological issues or dementia. It aims to improve understanding and care for hospitalized seniors.
AnconaAges 65 years+ - NCT04804878Recruiting

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 338 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.
