Figure 1

Percent agreement of E 2 values obtained by the 6 different immunoassay methods with the corresponding values measured by LC-MS/MS. Each bar graph shows the proportion of E2 values that are unknown (could not be compared to the LC-MS/MS values due to insufficient assay sensitivity), lower, in agreement, and/or higher than the values obtained by the mass spectrometry assay. Percent agreement of E2 values obtained by different immunoassay methods with the corresponding values measured by LC-MS/MS.
