MálagaAges 8–14 - NCT01553214RecruitingPhase 4
Blood donation study to improve white blood cell collection
This study tests a better way to collect white blood cells from healthy people who donate blood. It may help improve how reliably and safely white blood cells are collected for research or future treatments.
Bethesda, MarylandAges 18–75 - NCT00923221Recruiting
Donate blood for people with prostate cancer
This trial collects blood samples from adults with prostate cancer. It may help researchers learn more about the disease or how treatments work, without directly testing a new drug in the eligibility you provided.
Bethesda, MarylandAges 18 years+ - NCT01192048Recruiting
Study genetics in congenital heart disease
This study looks at how genes may contribute to congenital heart disease. It may help researchers better understand causes and risk in families like yours.
Columbus, OhioAges Any age - NCT01441089Recruiting

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.
