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.

Study brain-heart signals in acute stroke using MRI
This study looks at how the brain and heart interact right after an acute ischemic stroke. It may help doctors better understand what happens in the first hours of stroke and improve monitoring or future treatments.
Bern, Canton of BernAges 18–86 - NCT04377854Recruiting
Checking whether BNP predicts outcomes in advanced heart failure
This study looks at whether a blood test called BNP can help predict what happens over time in people being evaluated for advanced heart failure treatment. It may help doctors better plan care and follow-up for patients long-term.
Copenhagen, DKAges 18 years+ - NCT04844684Recruiting
Study hormones and bile acids in women with obesity
This study looks at how cortisol and bile acids are processed in non-menopausal women with obesity. The goal is to understand metabolism differences and potentially guide future treatments or dietary/medication approaches.
LilleAges 18 years+ - NCT05111210Recruiting
IL-23/IL-17 psoriasis treatment study to understand skin immune changes
This study looks at what’s happening inside the body in people with plaque psoriasis who start certain biologic medicines that target the IL-23/IL-17 immune pathway. It may help explain why these treatments work and what body changes are linked to response.
Paris, Île-de-France RegionAges 18 years+ - NCT05322343Recruiting
Study biobank and brain health in people age 55–80
This study collects blood samples to build a biobank and learn how brain health changes with age. Some participants may also do an MRI scan to better understand brain changes and immune response.
Bordeaux, BordeauxAges 55–80 - NCT05899387Recruiting
Study fluid after breast surgery
This study looks at a problem called seroma, which is fluid buildup, after certain breast surgeries. It compares different situations where implants or tissue expanders are used, to better understand what to expect and how to manage it.

Can blood tests improve lung cancer screening in smokers with artery disease?
This study looks at whether certain blood tests can help find lung cancer early in people who have smoked for a long time and also have artery disease. The goal is to see if adding these tests to current screening methods can better identify those at highest risk.
MarseilleAges 45–80 - NCT06418256Recruiting
Study of Spleen Function Using Surgical Samples
This study collects the spleen and blood from people having surgery to remove their spleen. By studying these samples, researchers hope to learn more about how the spleen works and what happens when it doesn't function properly.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 347 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.
