Checking for cancer DNA and tumor cells in bodily samples
This study looks for cancer-related material in blood, urine, and sometimes bone marrow. It may help researchers understand how to detect cancer activity and track it over time using less invasive tests.
Columbia, MissouriAges 18 years+ - NCT07476781Recruiting
Liquid biopsy study for solid tumours and brain tumours
This study collects samples of spinal fluid and blood from people with solid tumours that have spread to the brain or spine, or who have primary brain tumours. The goal is see if these samples can help doctors detect and monitor these cancers more easily.

Thoracic cancer data collection study
This study collects medical information from people with suspected or confirmed thoracic cancer. The goal is to learn more about these cancers and improve future care.
Ede, GelderlandAges 18 years+ - NCT06587828Recruiting
Looking at immune cells in people with autoimmune disease
This study collects blood, tissue, and other samples from people with autoimmune diseases like Crohn's disease, multiple sclerosis, or lupus. Researchers will study your immune cells (T cells) to learn what they are attacking, which could lead to better treatments in the future.
Orange, CaliforniaAges 18 years+ - NCT07750886Recruiting
Collecting samples for lymphoma research
This study collects blood and tumor tissue samples from people newly diagnosed with aggressive non-Hodgkin lymphoma who will receive standard chemotherapy. The goal is to improve future tests for detecting minimal residual disease (tiny amounts of cancer left after treatment).
Austin, TexasAges 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+ - 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+ - NCT07297394Recruiting

Common questions
- Are there clinical trials studying Blood sample collection?
- Yes. Clin2 currently lists 270 recruiting studies that include Blood sample 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 sample 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 sample 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 sample collection or a specific trial is right for you.
