Plewes et al. [109] examined urine NGAL-corrected urine creatinine (uNGAL/Ucr) using ELISA kits, and they observed statistically significantly higher levels of uNGAL/Ucr in the patients with severe AKI compared with patients with moderate AKI, mild AKI, and without AKI. Here, LCN2 is linked to acute kidney injury.
