The novel urinary markers of AKI are: neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule 1 (KIM-1), transforming growth factor beta-1, retionol-binding protein, cystatin C (Cyst-C), interleukin 18, liver-fatty-acid-binding protein, uromodulin, clusterin, and trefoil factor 3 [9,24]. Here, LCN2 is linked to acute kidney injury.
