Neutrophil Gelatinase associated Lipocalin (NGAL), Kidney Injury Molecule-1 (KIM-1), Liver-type Fatty Acid Binding Protein (L-FABP), Interleukin-18 (IL-18) and NF-κB are some novel AKI biomarkers that provide early and specific diagnosis of AKI with good predictive ability of clinical outcomes [34]. This evidence concerns the gene LCN2 and acute kidney injury.
