Correlation between Triage® NGAL device and ELISA. Shown is the correlation between plasma NGAL measurements obtained by Triage® NGAL device and research-based NGAL ELISA assay (Pearson r = 0.94, 95% confidence interval 0.89 to 0.96; P < 0.001). The regression line shown yielded a slope of 0.671 (95% confidence interval 0.600 to 0.741) and an intercept of 48.82 (95% confidence interval 18.66 to 78.99). ELISA, enzyme-linked immunosorbent assay; NGAL, neutrophil gelatinase-associated lipocalin.
