Elevated serum anti-müllerian hormone can now be used as an alternative to pelvic ultrasound to aid diagnosis of PCOS, according to updated guidelines released this week.

Although testing for anti-müllerian hormone (AMH) is not MBS subsidised, lead author and endocrinologist Professor Helena Teede says the cost of an ultrasound is “comparatively” higher.

“We will be advocating for [Medicare] access to AMH for this indication, just as we will be advocating for access to laser and light therapy [for PCOS-associated hirsutism],” she told AusDoc.

However, the new PCOS management guidelines cautioned against using serum AMH in adolescent girls aged 10-19 because of poor specificity and the risk of overdiagnosis.
