    Published 2025-06-01
    “…Results: Elevated uNGAL (median [interquartile range]: 500 ± 350 ng/ml) in the EMSD indicated sustained increases of SCr (> 48 hours); whereas much lower levels of uNGAL indicated either transient changes (< 48 hours; 150 ± 250 ng/ml) or no elevation of SCr (50 ± 97.5 ng/ml) (P < 0.01). Analysis of the entire cohort (N = 229) or the “strict” subset with complete SCr measurements (n = 129) (P < 0.01) yielded similar data. uNGAL was highly specific and moderately sensitive (specificity: 0.90 [0.83–0.95]; sensitivity: 0.82 [0.67–0.96]) to indicate sustained elevation of SCr (area under the curve–receiver operating characteristic curve: 0.86; confidence interval: [0.76–0.96] and odds ratio [OR]: 16.19; confidence interval: [5.63–59.02] for NGAL levels > 125 ng/ml). …”
