Siddappa et al. [50] evaluated serum and urine NGAL as the prognostic markers of AKI in a small cohort of patients with AP and reported satisfying diagnostic accuracy of the markers that were measured on day 1, following patients’ admission (area under the ROC curve of 0.8 and 0.9, respectively) (Table 3). The gene discussed is LCN2; the disease is alkaline phosphatase measurement.
