Receiver operating characteristic (ROC) curve analysis of diagnostic sensitivity and specificity of the plasma NGAL ELISA assay. The performance of plasma NGAL measurement assay in discriminating patients with pancreatic cancer from those without cancer (normal, acute, and chronic pancreatitis) was evaluated. The area under the curve (AUC) was 0.75, suggesting that the test is fairly accurate in distinguishing the two groups.
