Test background |
AMH can be used to assess ovarian reserve and has the advantage that, compared with FSH, inhibin A/B and ultrasound antral follicular count, levels are relatively unaffected by the menstrual cycle and typically show low intra-individual variation. With respect to Assisted Reproductive Technology (ART), AMH has been used to rationalise treatment regimes in controlled ovarian stimulation, thus reducing risk of hyper-stimulation (OHSS) and often reducing treatment costs. |

Clinical Indications |
Assessment of appropriate stimulation regimes in ART Risk mitigation of OHSS in fertility treatment. Occasionally used in differential diagnosis and monitoring of ovarian tumours |
||||||||||
Reference range | Adult males 10.2 – 82.8 pmol/L Adult females AMH levels decline with age and interpretation is therefore most appropriately made by the fertility specialist requesting the test and in conjunction with the antral follicle count.

Notes | Falsely low results may be obtained for this test due to biotin interference.
