What it measures
AMH (anti-Müllerian hormone) is made by the small developing follicles in the ovaries. Because the number of follicles reflects the eggs remaining, AMH is used as a guide to ovarian reserve. It does not measure egg quality and does not predict the chance of natural pregnancy on its own.
Why people test it
- Used as a guide to how many eggs remain, for example when thinking about when to start a family.
- Measured before IVF to help plan the dose of fertility medicines.
- Sometimes measured when polycystic ovary syndrome (PCOS) is being looked into, as levels are often higher.
Typical range
Ranges vary by lab and method, and AMH falls with age, so results are compared with age-based ranges. Hormonal contraception can lower the result. Your report shows the lab's own range.
Finger-prick or vein?
A vein sample is usually advised, though finger-prick kits are also offered. Hormone results from finger-prick samples can be affected by creams or gels on the fingers.
AMH can be measured on any day of the menstrual cycle.
