Blood markers in children with congenital hearing loss
This study looks at certain substances in the blood of children with congenital hearing loss (hearing loss present from birth) to see if they are different from children with normal hearing. It may help doctors understand why hearing loss happens and could lead to better treatments.

Study for cardiomyopathy linked to family or genes
This study looks at people with cardiomyopathy (or related heart muscle conditions) and those who may be at risk because of family history or genetic test results. It may help researchers better understand who is likely to develop the condition and how best to monitor or support them.
LondonAges Any age - 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.

Studying inflammation and social factors in breast cancer
This study looks at how inflammation and social factors (like stress or support) affect breast cancer patients before they start treatment. You may qualify if you are a woman, newly diagnosed, and have not yet had any cancer treatment.
Philadelphia, PennsylvaniaAges 18 years+ - NCT07465848Recruiting
Testing telomere measurement to help diagnose lung cancer
This study uses a simple blood test to measure telomeres (parts of your DNA) to see if it can help detect lung cancer earlier. Researchers will compare results from people with lung cancer, heavy smokers, and low-risk individuals to improve diagnosis.
Elche, AlicanteAges 45 years+ - NCT07447076RecruitingPhase 2
New treatments for recurrent ATRT brain tumor
This trial tests new treatments for children and young adults whose ATRT brain tumor has come back or grown. It aims to find if these therapies can help control the tumor.
San Francisco, CaliforniaAges 1–39 - 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 - NCT07427940Recruiting
Genetics and autism: a study of the omic profile
This study looks at the genetic and molecular profiles of children with autism spectrum disorder (ASD) to better understand the condition and find new treatments. It compares children with ASD who have no known genetic cause to those with a specific genetic syndrome.
MilanAges 3–15 - NCT06123962Recruiting
Identifying lung injury subtypes to guide treatment
This study looks at different patterns in patients with a severe lung condition called ARDS, to better understand why some respond to treatments differently. You may help doctors learn how to personalize care.
BeijingAges 18 years+ - NCT07362654Recruiting
Gluten challenge study in kids with celiac disease
This study looks at how the immune system of children with celiac disease responds to a small amount of gluten. It may help researchers understand the disease better and find new ways to monitor it.
MálagaAges 8–14 - NCT07356570Recruiting
Post-COVID care tracking study for long-term symptoms
This study follows people with lasting or complex COVID-19 symptoms who are already in a specialized care program. It aims to better understand and improve recovery after COVID.
Pierre-BéniteAges 18 years+ - NCT07328178Recruiting
Understanding IgE proteins in allergies and immune conditions
This study looks at IgE, a protein involved in allergic reactions, to better understand its role in different immune-related diseases. It aims to find out how different forms of IgE relate to health and disease, which may help improve diagnosis or treatment.
Leuven, Vlaams-BrabantAges 18 years+ - NCT07313007Recruiting
Gut bacteria chemicals in fatty liver disease
This study looks at whether the natural chemicals made by your gut bacteria from the food you eat could affect liver fat and health. If you have MASLD (a fatty liver condition), researchers want to measure these gut-produced substances to better understand the disease.
Pierre-BéniteAges 18–80 - NCT06906016Recruiting
New blood tests for hepatitis B
This study looks at new blood tests (biomarkers) to better understand chronic hepatitis B and how it affects treatment decisions. It may help doctors find better ways to manage your condition.

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.
