Recruiting studies
- NCT04392401Recruiting
Study immune changes in adults during ICU stay for COVID-19
This study looks at how your immune system responds while you’re in the intensive care unit (ICU) for COVID-19. Researchers will collect samples early in the ICU stay to better understand immune changes during the illness.
BronAges 18 years+ - NCT04857528Recruiting
Testing HPV DNA in anal and cervical tumors
This trial checks whether tumor samples contain HPV DNA (genetic material from the HPV virus). The goal is to improve detection in anal and cervical cancers, especially in patients planning standard radiation treatment.
Chicago, IllinoisAges 18 years+ - NCT04751760Recruiting
Test a new blood test for IgE allergy markers
This study checks whether a new blood test can measure allergy-related immune signals (IgE) in people with known or suspected allergies. If it works well, it could help doctors diagnose and track IgE allergies more easily.
ToulouseAges 6 months–99 years - NCT04537390Recruiting
Measuring AMH hormone levels in healthy girls
This study measures a hormone called AMH in girls before and after puberty. It’s done while participants have a routine outpatient surgery, to better understand what AMH levels look like in healthy children.
Chicago, IllinoisAges Up to 18 years - NCT04133077Recruiting
Biobank study using tumor tissue to grow patient tumor models
This study takes small samples of your breast tumor tissue after (or during) treatment and grows them in lab animals to better study breast cancer. It may help researchers test future ideas for treating aggressive breast cancer types like triple-negative or Luminal B.
Clermont-Ferrand, Puy-de-DômeAges 18 years+ - NCT03818412Recruiting
Liquid biopsy for soft tissue sarcoma
This study checks if a blood test can detect DNA from soft tissue sarcomas. The goal is to see if circulating tumor DNA can help doctors monitor the disease and plan treatment.
Toronto, OntarioAges 18 years+ - NCT02534649Recruiting
Drug-matching trial for adults with cancer DNA changes
This trial looks for the specific DNA or tumor changes in your cancer and then matches you to a targeted drug plan. It’s meant for people with early cancer that has not already been treated in this study.
BayonneAges 18 years+ - NCT01441089Recruiting
Donate blood for genetic testing in an NIH research study
This study collects blood from people already in an NIH (National Institutes of Health) clinical research program to run genetic tests. It may help researchers understand cancer and related inherited conditions by studying DNA changes.
Bethesda, MarylandAges 3 years+ - NCT01553214RecruitingPhase 4
Blood donation study to improve white blood cell collection
This study tests a better way to collect white blood cells from healthy people who donate blood. It may help improve how reliably and safely white blood cells are collected for research or future treatments.
Bethesda, MarylandAges 18–75 - NCT02051062Enrolling by invitationPhase 4
Blood-plasma study of botulism antitoxin in children
This trial studies how a botulism antitoxin (called BAT, heptavalent) moves through the body in children. It may help doctors better choose doses and timing for pediatric treatment by learning from blood samples after the first dose.
Ages 1 day–11 years - NCT01336855Recruiting
Provide blood for studies comparing HIV groups
This study collects blood to help researchers run multiple projects, including comparing people who are HIV-negative with people who have HIV. It may help advance knowledge that could improve future testing or treatments.
San Francisco, CaliforniaAges 18 years+ - NCT01192048Recruiting
Study genetics in congenital heart disease
This study looks at how genes may contribute to congenital heart disease. It may help researchers better understand causes and risk in families like yours.
Columbus, OhioAges Any age - NCT00027326Enrolling by invitation
Blood and Urine Study During Radiation Therapy
This study collects blood and urine samples from patients receiving radiation therapy to understand how the body responds to treatment. It may help researchers improve radiation therapy in the future.
Bethesda, MarylandAges 18–120 - NCT00034216Recruiting
Blood Collection Study for Cancer Patients and Healthy Volunteers
This study collects blood samples from people with cancer and healthy volunteers to help researchers understand cancer better. Your blood will be used for laboratory studies that may improve future cancer treatments.
Bethesda, MarylandAges 18 years+ - NCT00083512Recruiting
Blood and Urine Collection in Glioblastoma Radiation Therapy
This study collects blood and urine samples from patients receiving radiation treatment for glioblastoma (a serious brain tumor) to help researchers understand how the body responds to radiation therapy. Participating is straightforward—you provide samples during your regular treatment.
Bethesda, MarylandAges 18–120 - NCT00923221Recruiting
Donate blood for people with prostate cancer
This trial collects blood samples from adults with prostate cancer. It may help researchers learn more about the disease or how treatments work, without directly testing a new drug in the eligibility you provided.
Bethesda, MarylandAges 18 years+ - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT06277466Recruiting
Gene changes and diabetes risk study
This study looks at how certain gene changes affect blood sugar control in type 2 diabetes and also in people who have had pancreas surgery. It compares these groups with healthy volunteers to see how genes influence the risk of diabetes.
XuzhouAges 25–70 - NCT04979728Recruiting
Check whether home blood drops work for HIV monitoring
This study tests whether people with HIV can safely collect small blood samples at home using finger-pricks and devices (“dried blood spots”). It may help make HIV monitoring easier and more convenient while on certain HIV medicines.
Aurora, ColoradoAges 18 years+ - NCT05746793Recruiting
IVF pregnancy study to prevent pre-eclampsia in high-risk women
This trial studies ways to lower the risk of pre-eclampsia (dangerous high blood pressure in pregnancy) in women who are having a first pregnancy through IVF/ICSI or who have PCOS. It’s aimed at people considered higher risk for pre-eclampsia.

Blood test study to track markers in diabetes
This study measures “circulating biomarkers” (blood-based signals) in people with type 1 or type 2 diabetes, and in some people without diabetes who test positive for certain diabetes antibodies. The goal is to understand what these blood signals can tell us about diabetes development and progression.
Duarte, CaliforniaAges Any age - NCT06876064Recruiting
Tracking people at risk for rheumatoid arthritis
This study follows different groups of people—from those at high risk of developing rheumatoid arthritis to those recently diagnosed—to learn more about the disease. By joining, you help researchers understand who gets RA and why, which may lead to earlier detection and better care.

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.
