LCN2 and acute kidney injury: A similar study found that at the time of admission plasma NGAL was a better predictor of AKI (diagnosed based on RIFLE criteria) than serum creatinine.[21] In Bothrops snakebites presenting to an emergency centre in eastern Brazil [22], uNGAL levels were significantly higher in patients who developed AKI, but again were inferior to sCr (AUC-ROC of 0.75 versus 0.86, respectively).
