From: Serum neutrophil gelatinase-associated lipocalin at inception of renal replacement therapy predicts survival in critically ill patients with acute kidney injury

NGAL cut-off OR Sensitivity (%) Specificity (%) NPV (%) PPV (%)
≥ 580 ng/mL 4.79 50.0 82.7 82.7 50.0
≥ 360 ng/mL 6.69 82.1 59.2 90.6 41.1
≥ 190 ng/mL 3.31 89.3 28,4 88.5 30.1
  1. NGAL = neutrophil gelatinase-associated lipocalin; NPV = negative predictive value; OR = odds ratio; PPV = positive predictive value.
