Enzyme-linked immunosorbent assay measurements of antimüllerian hormone (AMH) in human blood are a composite of the uncleaved and bioactive cleaved forms of AMH

The leading ELISA for AMH provides a composite value of two biologically distinct forms of AMH. It is not known whether proAMH and AMHN,C have identical relationships to ovarian reserve, antral follicle counts, or other aspects of ovarian function. Hence, future research into the physiology and clinical utility of AMH should consider the two forms separately.
