On the other hand, Aydogdu et al. [21] demonstrated that plasma NGAL is a poor predictor of AKI occurrence in septic patients with an AUROC of 0.44, and a study by Martensson et al. [13] showed that it was a poor indicator (AUROC of 0.67) of AKI occurrence in the 12 hours following septic shock. This evidence concerns the gene LCN2 and acute kidney injury.
