Figure 1 Modified second-generation (Gen IIm) antimüllerian hormone (AMH) measurement versus original second-generation (Gen II) assay. The thick line shows the best fit with a simple conversion factor (1.51, 95% confidence interval 1.44–1.58). The thin lines show equivalence (solid line) and a conversion factor of 2 (dashed line).

Figure 2 Gen I, Gen II, and Gen IIm AMH versus age. Plots of antimüllerian hormone (AMH) concentration (pmol/L) against age (years) for the first-generation Diagnostic Systems Laboratories (Gen I) assay, the original (Gen II) and the modified (Gen IIm) second-generation assays, with the use of linear regression with a quadratic age function.

Supplemental Figure 1 Modified second-generation (Gen IIm) antimüllerian hormone (AMH) measurement versus antral follicle count (AFC). The line is a linear fit: log(AMH) = −1.41 + 1.59 log(AFC + 0.5).
