LCN2 and acute kidney injury: Comparing non-AKI patients with burn injury versus those without, mean NGAL concentrations were significantly higher among the non-burned population (109.9 [39.7] vs. 77.4 [32.1] ng/mL, P = 0.013), while mean NGAL levels between burned versus non-burned AKI patients were similar (300.4 [213.5] vs. 396.7 [393.7] ng/mL, P = 0.589).
