Many other biomarkers, such as neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (Kim-1), tissue inhibitor of metalloproteinase-2 (TIMP-2) × insulin-like growth factor-binding protein 7 (IGFBP7), and C–C Motif Chemokine Ligand 14 (CCL14) have been studied for diagnostic value in early AKI detection [4]. This evidence concerns the gene LCN2 and acute kidney injury.
