An anti-mullerian hormone (AMH) test is a blood test that measures the amount of AMH in a blood sample. AMH is produced by granulosa cells in ovarian follicles and is used as a marker of oocyte quantity. The test is mainly used to provide a snapshot of a womans reproductive health. Here are some reasons why a woman may need an AMH test:

• To check how many eggs she has left in her ovaries, which is called her "ovarian reserve".
• To determine if her ovarian mass is a granulosa cell tumor.
• To monitor her health and healing if she has certain ovarian cancers.
• To find out when she will enter menopause.
• To help diagnose the cause of infertility.
• To determine what dose of fertility medicine she may need to get the best response.
• To reveal how well she responds to injectable fertility drugs to stimulate her ovaries to mature multiple eggs in preparation for in vitro fertilization (IVF) .

Its important to note that while AMH is connected to a womans egg count, it doesnt predict her fertility (with or without treatments), or when shell go through menopause. Additionally, even if a womans AMH levels are in the typical range, other factors may influence her fertility.
