Anti-Müllerian Hormone (AMH)

An estimate of ovarian reserve. Unusually among female hormones, it can be measured on any day of the cycle.

Anti-Müllerian Hormone in the Biomarker Guide — what it is, why it is tested, and what moves the number.

Add-on markers can only be added to venous samples.

Timing

No fasting needed and no particular cycle day. AMH holds steady across the month, which is part of why it is used. The combined oral contraceptive pill lowers it, and it can still be below your usual level 3 months after stopping. Hormonal coils do not appear to.

Turnaround: the lab reports this test within 24 hours of receiving your sample, counted in working days. Most samples reach them within about 3 days of posting. Full detail on our Turnaround Times page.
