Blood tests could predict survival in ICU patients with severe infection
NCT ID NCT07332793
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how immune cells change in adults with severe infection (like sepsis) in the ICU. Researchers will collect blood samples and review medical records to see if certain immune patterns are linked to survival, organ failure, or longer hospital stays. The study does not provide any new treatment—it only observes and measures. About 200 adults will take part.

Who is studied
The study population consists of adult patients aged 18 years or older who are admitted to the intensive care unit (ICU) with severe infection, including sepsis. Participants are enrolled during the early phase of ICU admission and receive standard clinical care as determined by their treating physicians. This observational study does not involve assignment to experimental interventions.
