Kidney health study in young leukemia patients using ultrasound
This study tests whether a special ultrasound technique can detect early kidney damage in children and teens with acute lymphatic leukemia, before standard tests show any problems.
Erlangen, BaveriaAges 3–17 - NCT07156214Recruiting
Understanding RFC1-ataxia to find biomarkers
This study looks at a rare genetic condition called RFC1-ataxia (also known as CANVAS). It aims to find better ways to diagnose and track the disease. You may qualify if you have this condition, are between 18 and 80, and can agree to take part.
BolognaAges 18–80 - NCT05334069Recruiting
Blood test study for early cancer detection in patients
This study collects blood from people with cancer and people without cancer (or with possible cancer) to test whether new blood tests can detect cancer earlier. Your blood samples help researchers evaluate how well these tests work.
Anchorage, AlaskaAges 40–75 - NCT07255157Recruiting
Peripheral Helper T-cells in CVID
This study looks at a specific type of immune cell in people with Common Variable Immune Deficiency (CVID). It aims to learn more about how these cells behave and may help guide better treatments for this condition.
PessacAges 18 years+ - NCT07745530Recruiting
How platelets affect HIV reservoirs in the blood
This study looks at how platelets (small blood cells that help with clotting) might influence the hidden HIV that remains in your body even when your viral load is undetectable. The goal is to understand why some people's immune systems don't fully recover despite effective HIV treatment.
TourcoingAges 18 years+ - NCT06814990Recruiting
Heart and liver study for TIPSS patients
This study uses MRI and echocardiography to check heart function in people with alcohol-related liver cirrhosis who need a TIPSS procedure. It aims to learn more about how the heart works in these patients.
Jena, ThuringiaAges 18–99 - NCT07743021Recruiting
Blood sample study for better health screening
This study collects blood samples and health information over time to improve early detection of diseases. It may help researchers find ways to prevent serious conditions.
BalatonfüredAges 40 years+ - NCT07046936Recruiting
Mitochondria and resilience in gynecologic cancer
This study looks at how cell energy (mitochondria) relates to a person's ability to bounce back during treatment for advanced ovarian or endometrial cancer. If you qualify, you'll have tissue and blood samples analyzed alongside standard therapy to help find why some people handle treatment better than others.
Charlotte, North CarolinaAges 50 years+ - NCT07232550Recruiting
Breathing study for children needing bronchoscopy
This study collects samples (like fluid from the lungs) during a planned bronchoscopy to look for new ways to understand and predict children's breathing problems. It might help if your child already needs this procedure for a medical reason.
WarsawAges Up to 17 years - NCT05934474Recruiting
Study collects blood to learn about inflammation in mental illness
This study collects biological samples to better understand how “inflammation” in the body may relate to certain mental health conditions. Your results may help doctors learn more about causes and future treatments, even if the study does not give a new drug.
NantesAges 18 years+ - NCT07728734Enrolling by invitation
Predicting recovery after a brain bleed
This study is testing a way to predict how well people will recover after a brain bleed (intracerebral hemorrhage). It uses information from the first 24 hours to help doctors and families understand the chances of getting better.
Badalona, BarcelonaAges 18 years+ - NCT07436637Recruiting
Blood test for colorectal cancer screening
This trial is testing a blood test called Guardant Shield to see if it can effectively screen for colorectal cancer (a common cancer of the colon or rectum). If you're between 45 and 85 and overdue for a screening, this test could be a simpler alternative to colonoscopy or stool tests.
Miami, FloridaAges 45–85 - NCT02530658Recruiting
Sequencing children’s tumor and normal tissue samples

Common questions
- Are there clinical trials studying Blood sample?
- Yes. Clin2 currently lists 699 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.
