Recruiting studies
- NCT04792684Recruiting
Collecting colon samples from adults with colon findings
This study collects body samples to help evaluate tests for people with suspected or newly diagnosed colorectal conditions, often around the time of colonoscopy or surgery. Depending on the arm, you may be asked to have a colonoscopy soon or to provide samples before planned surgery.
Chula Vista, CaliforniaAges 45–84 - NCT06046651Recruiting
Blood sample collection for lab research
This study collects blood samples from healthy adults to help researchers learn more about how to run lab tests. It involves one visit or at-home collection and might help future medical research.
San Francisco, CaliforniaAges 18 years+ - NCT06620627Recruiting
Blood test for early cancer detection before colonoscopy
This study is testing a new blood test that might help find cancer early. If you are 40 or older and planning a routine screening colonoscopy, you may be able to join. You will give a blood sample before the colonoscopy, and the researchers will see if the test can detect signs of cancer.
Austin, TexasAges 40 years+ - NCT05505669Recruiting
Blood test study to track markers in diabetes
This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.
Duarte, CaliforniaAges Any age - NCT05705531Recruiting
Cardiac MRI study of heart health after Hodgkin lymphoma treatment
This study looks at how certain blood-related “growth patterns” connect to long-term heart health after treatment for classical Hodgkin lymphoma. It may help doctors better predict who could develop heart problems and how to monitor them over time.
Mobile, AlabamaAges 7 years+ - NCT06385288Recruiting
Blood and tissue study in high-risk sarcoma
This study collects blood and tissue samples from people with high-risk soft tissue sarcoma before their surgery. The goal is to learn how the immune system responds to pre-surgery treatments like radiation and hyperthermia (heat therapy).
Tübingen, Baden-WurttembergAges 18 years+ - NCT05530759Recruiting
Testing blood and tumor samples for diagnostic cancer markers
This study looks at blood and tumor tissue to find signs (markers) that can help diagnose or better understand metastatic cancer. You may be able to join if you’re getting surgery or a biopsy to remove a tumor and there’s a safe way to collect samples.
Rochester, MinnesotaAges 18 years+ - NCT04917705Recruiting
Blood and tissue tests to find markers in muscle and skin disease
This study looks for blood and tissue “biomarkers” (measurable clues in samples) to help diagnose and predict outcomes in inflammatory muscle diseases and systemic sclerosis (a skin/organ condition). If you’re being evaluated for myopathy or early scleroderma, it may help doctors sort out the cause and follow your health more closely.
Strasbourg, Bas-RhinAges 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+ - NCT06605404Recruiting
Pan-tumor study of a blood test after cancer surgery
This study is testing a new blood test that looks for leftover cancer cells after surgery. It is for people with different types of solid tumors who are planning to have surgery to cure their cancer. The goal is to see if the test can help guide future treatment decisions.
San Diego, CaliforniaAges 18 years+ - NCT06624865Recruiting
Gut bacteria and small-intestine neuroendocrine tumor study
This study looks at how bacteria in your gut may affect the growth of small-intestine neuroendocrine tumors. If you are having surgery to remove one of these tumors, the research team will collect samples and data to better understand the link between your gut bacteria and the tumor.
Lyon, FranceAges 18 years+ - NCT04925089Recruiting
Testing biomarkers in localized soft tissue cancer before surgery
This study looks at lab biomarkers (signs in tumor tissue) in people with localized leiomyosarcoma. It also requires treatment with chemotherapy before surgery to see if the information from tumor samples can help guide care.
Ann Arbor, MichiganAges Any age - NCT00900198Recruiting
Give cancer tissue samples to help future cancer research
This study collects tissue or other cancer-related samples to help researchers better understand cancer and develop better tests or treatments. You can join if you are being evaluated for or treated for cancer, and you agree to let your samples be used for research.
Sacramento, CaliforniaAges 2 months+ - NCT00001405Recruiting
Blood Cell Collection Study for Immune and Blood Disorders
This study collects blood cells and bone marrow from people with immune system or blood disorders, and from healthy volunteers. Researchers will study these cells and may convert them into special stem cells (iPS cells) to better understand diseases and develop treatments.
Bethesda, MarylandAges 18–70 - NCT07623265Recruiting
Understanding Immunotherapy Response in Liver Cancer
This study collects tumor samples and medical information from patients with liver cancer to understand why some patients respond better to immunotherapy (immune-boosting drugs) than others. The goal is to improve treatment selection and outcomes for future patients.
AntwerpAges 18 years+ - NCT03319446Enrolling by invitation
Sharing anonymous samples for a diagnostic test
This trial collects and stores anonymous samples from consenting adults. It helps researchers evaluate or improve diagnostic testing without using your personal identity.

ILD and autoimmune conditions registry and sample storage
This study collects health information and may store blood or other samples to learn more about interstitial lung disease (ILD) and autoimmune-related conditions. Joining could help researchers understand different causes of ILD and improve future care.
Montreal, QuebecAges 18 years+ - NCT05300997Recruiting

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.
