Blood test may predict ICU death risk
NCT ID NCT07493759
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study examined whether a blood test called the Systemic Immune-Inflammation Index (SII) can predict the risk of death in critically ill patients in the intensive care unit (ICU). Researchers looked back at the records of 570 adults admitted to the ICU. They found that higher SII levels at admission were linked to a higher chance of dying during the ICU stay. The goal is to see if this simple, cheap test can help doctors quickly identify high-risk patients.
