Testing a protein marker for adenomyosis diagnosis
This study measures a protein called L-PGDS (lipocalin-type prostaglandin D synthase) in blood, urine, and tissue samples to see if it can help diagnose adenomyosis (a condition that causes heavy periods and pelvic pain). Researchers are comparing levels in women with and without adenomyosis who are having a hysterectomy, as well as in women without symptoms.

Genetic test to guide first or second treatment for advanced cancer
This study looks at whether using a detailed genetic test of your tumor can help pick the best first or second treatment for advanced lung, colon, breast, or bladder cancer. The goal is to see if this personalized approach helps people live longer.
Chapel Hill, North CarolinaAges 18 years+ - NCT06899854Recruiting
Collecting blood and tissue from patients with liver cancer
This study collects blood and tumor tissue samples from people with primary liver cancer who are starting their first treatment (systemic therapy or surgery). The samples help researchers learn more about these cancers and how to improve future treatments.

LeuvenAges 18–60 - NCT07131605Recruiting
How weight-loss surgery affects heart health and inflammation
This study looks at how weight-loss surgery affects heart health by checking markers of inflammation in the blood and how blood vessels work. It may help understand why surgery lowers heart risk for people with obesity.

Common questions
- Are there clinical trials studying Blood samples?
- Yes. Clin2 currently lists 695 recruiting studies that include Blood samples, 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 samples 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 samples 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 samples or a specific trial is right for you.
