ShenyangAges 18–80 - NCT04858217Recruiting
Testing blood and joint fluid tests for hip or knee infection
This trial checks how accurate certain blood tests and joint-fluid (synovial) tests are at identifying infections around hip or knee replacements. It also looks at whether these tests are worth the cost, to help doctors choose the best next step.
BolognaAges 18 years+ - NCT05536219Recruiting
Study how autoantibodies affect virus levels in severe lung infections
This study measures blood immune “autoantibodies” that may affect how much virus is in the body during severe respiratory infections. It may help doctors understand which patients are more likely to have higher virus levels and could guide future treatment choices.
Bron, RhoneAges Any age - NCT04875702RecruitingPhase 4
Compare urate targets to reduce gout attacks or symptoms
This study compares two different treatment goals for a blood level called urate in people with gout. The goal is to see which approach lowers gout flares better while helping people feel better.
South Birmingham, AlabamaAges 18–90 - NCT06206486Recruiting
Gut germs and pain after kidney transplant
This study looks at whether the germs in your gut (microbiome) and certain chemicals in your blood affect pain after a kidney transplant. By joining, you may help doctors better understand and manage pain for future kidney transplant patients.
Chicago, IllinoisAges 18 years+ - NCT06138249Recruiting
Vitamin D supplements for low vitamin D levels
This trial tests two forms of vitamin D (cholecalciferol and calcifediol) to see which better raises vitamin D levels in people with a deficiency. It may help you if your vitamin D is low, but you don't have osteoporosis or liver/kidney problems.
BariAges 18–80 - NCT00823654Recruiting
Blood tests during treatment to track ovarian egg supply
This study measures blood biomarkers to understand how breast cancer treatment affects a person’s future fertility (ovarian reserve). It may help patients learn more about egg supply changes after chemotherapy and hormone-related treatments.
Basking Ridge, New JerseyAges 18–44 - NCT06126601Recruiting
Study on blood enzyme levels after pancreas surgery
This study checks if high levels of a certain enzyme (called amylase) in the blood after pancreas surgery can help predict recovery and complications. The goal is to improve patient safety after the operation.
DresdenAges 18–85 - NCT06047093Recruiting
Study of Hepatitis B Virus in the Liver
This study collects a small sample of liver cells to understand how hepatitis B virus behaves in the liver and how the immune system responds. This could help improve future treatments for chronic hepatitis B.
LyonAges 18 years+ - NCT06007755Recruiting
Finding blood markers for confusion after heart surgery
This study is looking for certain substances in the blood that may show up if a person becomes confused or delirious after heart surgery. The goal is to find early warning signs so doctors can help prevent or treat this confusion.
Wuhan, HubeiAges 18 years+ - NCT05866796Recruiting
Test blood patterns to predict problems after liver transplant
This study checks whether a special blood test can predict who is at higher risk of graft loss (the transplanted liver not working well) and death after a liver transplant. It may help doctors identify higher-risk patients earlier and tailor follow-up care.
Ghent, FlandersAges 18 years+ - NCT05848310Recruiting
Blood test before surgery to predict biliary atresia outcome
This study looks at a specific pre-surgery blood marker called FGF19 (and related liver blood tests) in children with biliary atresia. The goal is to see whether the blood results before surgery can help predict how well children recover after surgery.

- Yes. Clin2 currently lists 184 recruiting serum studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a serum trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a serum trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
