Blood tests to study infection risk and immune problems
Part of Genetic & congenital, Immune system & allergy, Infections clinical trials.
This study looks at how the immune system works in people who have—or might have—an increased risk of infections. It also enrolls their healthy blood relatives so researchers can compare immune features; results may help doctors understand who is at higher risk and why.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re older than 1 month
- You (or your guardian) can give informed consent after being explained the study
- You must have a primary doctor outside the NIH, and you may need a letter confirming your health history
- You and your blood relatives agree to have blood and tissue saved for future immune-related research
- Your patient must enroll first so relatives can enroll too

This study screens people who may have an inherited immune system condition (like problems with immune cell growth or death) and their blood relatives. The goal is to understand the condition better by collecting blood samples for testing.
This study looks at immune system differences that can make some people get unusual or frequent fungal (fungus) infections. It may help researchers better understand these conditions, and you may be asked to store blood for future research.
This study collects blood (and sometimes related samples) to learn how genes and the immune system work in people with primary immunodeficiency (PID) or in family members who may not have it. The goal is to improve understanding of rare immune conditions and help guide future care.
This research study investigates problems with immune system cells called phagocytes that help fight infections. Researchers will study patients with suspected immune defects and their blood relatives to better understand these conditions and develop better care.
This is a long-term study that evaluates and follows patients with inflammatory conditions related to infections or immune system problems. Researchers at the National Institutes of Health want to understand these conditions better and may ask you to participate in related studies.
This study looks for genetic causes of immune problems, such as unusually frequent infections, abnormal allergies, or autoimmune or inflammation conditions. It may help by improving how doctors understand these disorders and by matching families with possible genetic diagnoses.
