Promising diagnostic injury markers include kidney injury molecule 1 (KIM-1), 16 interleukin 18 (IL-18), 18 neutrophil gelatinase-associated lipocalin (NGAL), 19 liver-type fatty acid binding protein (L-FABP), 20 cystatin C, 21 N-acetyl-beta-D-glucosaminidase (NAG), 22 beta-2-microglobulin (B2M) 23 zinc-alpha-2-glycoprotein (AZGP1), 24 and cytochrome C. 25 Furthermore, several additional biomarkers have been postulated to be of prognostic or diagnostic value in connection with AKI (reviewed in e.g.)10,17,26,27. This evidence concerns the gene AZGP1 and acute kidney injury.
