Blood test duo may spot sepsis danger early in seniors
NCT ID NCT07332715
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether combining two blood markers—uric acid/albumin ratio and lactate—can help predict which older adults (65+) with sepsis will develop kidney injury, need blood pressure support, or die within 28 days. Researchers will follow 80 ICU patients who do not have kidney damage at the start. The goal is to find an easy, low-cost way to identify high-risk patients early and guide treatment.

Who is studied
The study population consists of critically ill adult patients aged 65 years and older who are admitted to a tertiary-level intensive care unit with a diagnosis of sepsis based on SEPSIS-3 criteria. All participants are required to have baseline measurements of serum uric acid, albumin, and lactate levels at the time of ICU admission and no evidence of acute kidney injury at presentation. The study focuses on evaluating the prognostic value of routinely available biochemical markers in predicting adverse clinical outcomes, including acute kidney injury, vasopressor requirement, and short-term mortality during intensive care follow-up.
