FABP1 and acute kidney injury: Recent publications propose the measurement of new early biomarkers of AKI such as Liver Fatty Acid Binding Protein (L-FABP), interleukin-18 (IL-18), Tissue Inhibitor Metal Proteinase-2* Insulin Growth Factor Binding Protein-7 (TIMP2*IGFBP7), Mid-Regional pro-Adrenomedullin (MR-proADM), Kidney Injury Molecule-1 (KIM-1), and Neutrophil Gelatinase-Associated Lipocalin (NGAL) [33,34,35,36].
