Lactate–Albumin Ratio Tied to TBI Mortality Admission biomarker showed prognostic value alongside clinical scoring systems in pediatric intensive care By Kathryn Wighton April 17, 2026 3 min MDSpire News Share Summary Takeaways Listen Insight Report Clinical Scorecard Quiz Poll 1 The lactate-to-albumin ratio (LAR) is associated with mortality in pediatric traumatic brain injury (TBI) patients. 2 In a study of 98 pediatric TBI patients, the overall mortality rate was found to be 9%. 3 Non-survivors exhibited significantly higher PRISM III scores and lower pediatric Glasgow Coma Scale scores compared to survivors. 4 LAR values were notably higher in non-survivors, indicating its potential as a prognostic marker for mortality. 5 This study is the first to evaluate LAR as a predictor of mortality in pediatric TBI, despite its limitations.
