Urinary calprotectin and NGAL are emerging biomarkers for distinguishing between prerenal and intrinsic acute kidney injury (AKI) in kids, with this study focusing on their effectiveness compared to KIM-1.
The analysis included 139 pediatric subjects and found that calprotectin levels were significantly higher in intrinsic AKI patients (22 times more) than in prerenal AKI patients, while NGAL levels were also elevated (9 times more).
Overall, calprotectin demonstrated superior diagnostic accuracy (AUC of 0.90) compared to NGAL (0.73) and KIM-1 (0.50), making it a better marker for differentiating types of AKI in the pediatric population
