For patients with AKI, the median uNGAL and KIM-1 concentrations were 107 ng/ml (IQR, 22.4 to 935) and 0.19 ng/ml (IQR, 0.10 to 0.43), respectively, which were significantly higher than those for non-AKI patients: uNGAL of 23.2 ng/ml (IQR, 9.6 to 93) and KIM-1 of 0.13 ng/ml (IQR, 0.08 to 0.25) (both P-values <0.001 by Mann–Whitney U test). This evidence concerns the gene HAVCR1 and acute kidney injury.
