Figure 2.

Mean vs. absolute difference plot comparing the NGAL in-house assay with the commercial ELISA assay. Absolute differences were calculated as values obtained using the TRIFMA assay subtracted from values obtained using the ELISA assay. The 95% limits of agreement ( ± 1.96 SD) are ± 63 μg/L. SD is the standard deviation of the difference.
