This study looks at a substance in the blood called neurofilaments, which may help doctors understand early brain development in babies born a few weeks early. If your baby already needs a blood test, researchers will use a small extra sample to learn more.
LiègeAges Up to 3 weeks - NCT07151118Recruiting
Blood test for advanced biliary tract cancer
This study uses a simple blood test (ctDNA) to learn more about the genetic makeup of advanced biliary tract cancers. It may help researchers understand how these cancers respond to treatment, and it doesn't involve any extra drugs or procedures—just blood draws.

Better understanding chromosome changes in children with developmental disorders
This study uses a new technique called optical mapping to better understand chromosome changes found in children with neurodevelopmental disorders. It aims to give clearer answers to families about these genetic findings.

AI for diagnosing and treating brain diseases in older adults
This study uses artificial intelligence to help diagnose and treat brain diseases that affect older adults, such as Parkinson's and Alzheimer's. Researchers will compare AI methods with standard care to see if they can improve diagnosis and treatment.

NETosis markers for predicting blood clots in MPN
This study looks at certain markers in the blood to see if they can predict blood clots in people with myeloproliferative neoplasms (MPN) like polycythemia vera, essential thrombocythemia, or pre-myelofibrosis. It is only for people who have a specific JAK2 mutation and are at high risk for clots, and who are already enrolled in another trial and a biobank.

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sample, 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 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 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 or a specific trial is right for you.
