What this test measures
The AMH test measures the level of Anti-Müllerian Hormone in the blood, a hormone produced by cells within the ovarian follicles. AMH is produced by granulosa cells in ovarian follicles from 36 weeks of gestation until menopause, with the highest production occurring in the preantral and small antral stages of folliculogenesis. This hormone plays a crucial role in regulating the recruitment of follicles from the resting pool and controlling which follicles become dominant during the menstrual cycle.
Unlike other reproductive hormones that fluctuate significantly throughout the menstrual cycle, AMH levels remain relatively stable throughout the month, making it a reliable marker that can be tested at any time during the menstrual cycle. The test provides valuable information about a person's ovarian reserve - essentially an estimate of how many eggs remain in the ovaries. This test measures AMH levels to determine how many small follicles are present, which provides a measure of roughly how many eggs are left in a woman's reserves. The results can help healthcare providers assess reproductive health and guide fertility treatment decisions.
Who should consider this test
You might consider this test if you are experiencing any of the following:
- Individuals trying to conceive who want to assess their ovarian reserve and fertility potential
- Those considering egg freezing or fertility preservation to understand their optimal timing
- Individuals with irregular menstrual cycles, missed periods, or symptoms of hormonal imbalance
- Those with a family history of early menopause or primary ovarian insufficiency
- Individuals being evaluated for polycystic ovary syndrome (PCOS) as part of comprehensive hormone testing
- Those undergoing fertility treatments who need ovarian reserve assessment for treatment planning
What to expect
Preparation
No special preparation is required for the AMH test. The test can be performed at any time during the menstrual cycle as AMH levels remain stable throughout the month. There is no need to fast or avoid medications before testing.
Sample Type
A simple blood sample drawn from a vein in the arm
Collection
The collection process takes just a few minutes. A healthcare professional will use a small needle to draw blood from a vein, typically in the arm. The sample is then sent to a laboratory for analysis.
Turnaround
Results are typically available within 2-5 business days after the laboratory receives the sample. Results will be provided through a secure online portal with detailed reference ranges and explanations.
Understanding your results
AMH levels are measured in nanograms per milliliter (ng/mL), and experts generally consider levels between 1.0-3.0 ng/mL to be in the average range. However, what constitutes normal varies significantly with age, as AMH levels naturally decline with age, making it normal to see lower ovarian reserve in the 30s, 40s, and 50s. It's important to understand that the AMH test cannot predict fertility or the ability to get pregnant, as egg quality, age, and overall reproductive health all contribute to fertility potential.
| Population | Reference Range | Notes |
|---|---|---|
| Reproductive Age Women (General) | 1.0-4.0 ng/mL | Most favorable range for reproductive health and fertility treatments |
| Ages 20-25 | 3.3-4.2 ng/mL | Peak reproductive years with highest expected levels |
| Ages 30-39 | 1.5-2.4 ng/mL | Normal age-related decline in ovarian reserve |
| Ages 40-44 | 0.52-0.88 ng/mL | Expected lower levels approaching perimenopause |
| Postmenopausal | Undetectable to <0.1 ng/mL | AMH becomes undetectable at menopause |
Reference ranges shown are general guidelines. Your lab report will include the specific reference range used by the laboratory that processed your sample, which is the authoritative range for interpreting your results.
What does a “Low” result mean?
Low AMH levels, typically defined as under 1.0 ng/mL, may indicate diminished ovarian reserve. AMH levels below 8 pmol/L (approximately 1.1 ng/mL) have shown high sensitivity for diagnosing primary ovarian insufficiency in women with menstrual irregularities. Low levels may suggest that fewer eggs remain available and could indicate that menopause may occur earlier than average. Lower serum AMH levels are strongly correlated with the likelihood of early menopause, and this association remains significant regardless of other risk factors for premature ovarian aging. However, it's important to note that low AMH does not necessarily mean pregnancy cannot occur naturally, as egg quality and other factors also play important roles in fertility.
What does a “High” result mean?
Higher AMH levels may be associated with polycystic ovary syndrome (PCOS), a hormonal condition that can affect ovulation and fertility. Studies suggest that AMH levels of 3.9 ng/mL or higher may be associated with PCOS, with some research showing individuals with AMH levels ≥ 4.45 ng/mL having a 9.35 times higher likelihood of developing PCOS. Elevated AMH levels typically indicate a higher number of follicles in the ovaries, which may seem beneficial but can sometimes be associated with ovulation difficulties. In rare cases, abnormally high AMH could indicate an ovarian tumor, such as granulosa cell tumors, which can produce elevated levels of this hormone. High AMH levels may also indicate an increased risk of ovarian hyperstimulation syndrome during fertility treatments.
Privacy & confidentiality
All test orders are authorized and results reviewed by an independent, board-certified physician who is not the patient's personal doctor. Your AMH test results are completely confidential and handled with the highest level of privacy protection. Results are <u>not reported to your doctor</u> unless you specifically choose to share them, and they are <u>not part of your medical records</u> maintained by healthcare providers. The test will <u>not appear on insurance statements</u> or explanation of benefits forms, ensuring complete discretion. Your personal health information is never shared with employers, insurance companies, or any third parties without your explicit consent. All results are delivered through a secure, encrypted online portal that only you can access with your unique login credentials. This private testing approach allows individuals to gain valuable insights into their reproductive health and make informed decisions about their fertility journey without any concerns about privacy or confidentiality.
