Study of immune antibodies after first-time EBV infection
This study looks at how the immune system’s antibodies behave after a first-time EBV infection, including whether they mistakenly react with the body’s own tissues.

Testing blood and stool for colon cancer in Lynch syndrome
This study collects blood and stool samples to see how well they can detect colorectal cancer or advanced growths in people with Lynch syndrome (an inherited colon cancer risk) or suspected Lynch syndrome. It may help find cancer or precancer earlier, which can improve next-step decisions.

Testing heart-related blood markers in people with diabetes and heart failure
This study looks for blood markers that may help explain or predict heart problems in people who have type 2 diabetes and heart failure. To join, you may also need to be having a planned heart procedure where doctors can collect study information.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT07715682Recruiting

This trial studies blood and tissue samples from people with COPD, IPF, or lung cancer to find markers that can help diagnose and predict these conditions. It aims to discover why some lung diseases progress to cancer.
Milan, MilanAges 18 years+ - NCT05791162Recruiting
Looking at immune cell ratios in IgA kidney disease
This study looks at how certain immune cells in blood relate to IgA nephropathy, a kidney condition. It may help doctors understand which patients are likely to do better and guide future care.

Blood collection for research study
This study collects a blood sample from healthy adults to help with research. You may be able to join if you meet basic health requirements and have not donated blood recently.

Common questions
- Are there clinical trials studying Blood collection?
- Yes. Clin2 currently lists 338 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.
