Study how pertussis germs and immune response affect severity
This study looks at children with suspected pertussis (who need a PCR test) and compares how the bacteria and the immune response relate to how sick they become. It may help doctors understand why some children have worse symptoms and guide future care.

Study of immune cell activity in systemic sclerosis
This study looks at a specific type of immune cell activity (called neutrophil extracellular traps) in the blood of people with systemic sclerosis, other connective tissue diseases, and healthy volunteers.

Finding biomarkers in Langerhans cell histiocytosis
This study is looking for adults with Langerhans cell histiocytosis (LCH) and also for adults with certain lung conditions (like cystic lung disease or emphysema) or healthy smokers to act as controls. The goal is to find biomarkers (signs in the body) that can help doctors diagnose LCH, predict how it will progress, and see how well treatment is working.

Back pain study: testing a blood protein linked to MRI findings
This study looks at how a protein in your blood (called BDNF) relates to the severity of your lower back condition, as seen on MRI. It may help doctors better understand and treat back pain in the future.
Daegu, DaeguAges 20–80 - NCT07803055Recruiting
Blood test for early signs of Alzheimer's disease
This study looks at tiny particles in the blood that may show early signs of Alzheimer's disease. It aims to help with earlier diagnosis and monitoring, which could lead to better care and treatment opportunities.
RomeAges 55–80 - NCT06536127Recruiting
Immune cells in non-spreading rectal cancer treatment
This study is looking at immune cells (NK cells and ImmunoScore) in the blood of people with rectal cancer that hasn't spread. It may help doctors learn more about how the immune system responds to standard chemoradiation treatment.
AvignonAges 18 years+ - NCT05409794Recruiting
Testing blood lithium levels in people with depression and suicidality
This study checks how much lithium is naturally present in the blood and whether that relates to suicidal thoughts or attempts in people with a current major depressive episode. It may help researchers understand biological factors linked to suicide risk and improve future prevention.
MontpellierAges 18 years+ - NCT05449119Recruiting
Study links gut health, diet, and thinking and movement in seniors
This study looks at how differences in gut bacteria and nutrition may relate to changes in thinking and movement in people over 75 who have a reduced appetite (“small eaters”). It may help doctors better understand what could be contributing to these problems and how nutrition might play a role.
DijonAges 75 years+ - NCT07776379Recruiting
Predicting recovery with BDNF blood levels in chronic low back pain
This study looks at whether a protein in your blood, called BDNF, can help predict how well you might do with chronic low back pain. By participating, you may help doctors better understand and treat this condition.
Daegu, DaeguAges 20–80 - NCT07769151Recruiting
BIO-FUNCTION test for predicting transplant risks
This study tests a new lab test called BIO-FUNCTION that may help doctors predict the risk of serious complications after a stem cell transplant. It aims to make transplants safer by identifying patients who might need extra support.
Detroit, MichiganAges 18 years+ - NCT07772570Recruiting
Studying blood markers in coronary artery disease
This study collects blood samples and images from patients with heart muscle damage or those undergoing coronary angiography. The goal is to find new biomarkers that could improve diagnosis and treatment of coronary artery disease.

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.

Common questions
- Are there clinical trials studying Blood sampling?
- Yes. Clin2 currently lists 684 recruiting studies that include Blood sampling, 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 sampling 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 sampling 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 sampling or a specific trial is right for you.
