Understanding your fertility health doesn't have to wait until you are actively trying to conceive. AMH testing for ovarian reserve is a straightforward blood test that can offer meaningful insights into your reproductive health picture — helping you make informed decisions, at your own pace, in your own time.
Whether you are exploring your options in London or simply want to understand more about your hormonal health, this guide explains what an AMH test is, how it works, and what the results may suggest.
What Is an AMH Test? A Clear Definition
Anti-Müllerian Hormone (AMH) is a protein hormone produced by the small follicles in the ovaries. It is widely used as a marker of ovarian reserve — a clinical term that refers to the number and quality of eggs remaining in the ovaries.
In simple terms: An AMH blood test measures a hormone that may indicate how many follicles your ovaries currently contain. It is one of the most widely used fertility screening markers in the UK, and unlike some hormonal tests, it can be taken at any point in your menstrual cycle, which may offer practical scheduling flexibility.
AMH levels naturally decline with age, and the test result can suggest whether your ovarian reserve appears typical, lower, or higher than expected for your age group.
Practical Insight: AMH alone does not predict fertility or the ability to conceive. It is one piece of a broader health picture and should be considered alongside other factors.
Why Ovarian Reserve Matters: Understanding the Bigger Picture
The number of eggs a person has at any given time is not fixed — it gradually decreases throughout life. Most individuals are born with all the eggs they will ever have, and from puberty onwards, that supply diminishes month by month.
Ovarian reserve testing, such as AMH blood work, can help to:
- Provide a general indication of where your egg supply may sit relative to your age
- Highlight whether further conversations with a healthcare professional may be beneficial
- Inform personal decisions around family planning timelines
- Support monitoring in those who have undergone treatments affecting ovarian function, such as chemotherapy
Practical Insight: This type of testing is educational and informational. Results suggest trends rather than certainties, and a single result should always be reviewed in context.
Who May Benefit From AMH Testing?
AMH testing is not exclusively for those experiencing fertility difficulties. Many people across London choose to have this test as part of a proactive approach to understanding their hormonal health.
You may wish to consider an AMH test if you:
- Are aged 25–45 and want to understand your current ovarian reserve
- Have a family history of early menopause or premature ovarian insufficiency
- Have been diagnosed with conditions such as polycystic ovary syndrome (PCOS) or endometriosis
- Have previously undergone treatments that may have affected ovarian function
- Are considering egg freezing and want a baseline understanding before consulting a specialist
- Have been trying to conceive for some time and want to gather more information
- Simply want to take a proactive approach to your reproductive health
Practical Insight: This test is available to individuals regardless of whether they are currently planning a pregnancy. It is a personal health awareness tool.
What Do AMH Results Mean? Understanding Your Levels
AMH results are typically reported in pmol/L (picomoles per litre) in the UK. The following table provides a general reference guide. Please note these are broad indicators and must be interpreted in context.
| AMH Level (pmol/L) | General Indication |
|---|---|
| > 25.0 | May suggest a higher ovarian reserve; sometimes seen in PCOS |
| 15.0 – 25.0 | Generally considered within a typical range for reproductive age |
| 7.0 – 14.9 | May suggest a low-normal ovarian reserve |
| 2.2 – 6.9 | May suggest a reduced ovarian reserve |
| < 2.2 | May suggest a very low ovarian reserve; worth discussing with a healthcare professional |
Important: These figures are reference ranges only. AMH results should always be interpreted alongside your age, menstrual history, and overall health context by a qualified healthcare professional.
Practical Insight: A single AMH result is not a diagnosis. It is a data point that can inform conversations with your healthcare team.
AMH vs Other Fertility Hormone Tests: A Quick Comparison
AMH is often considered alongside other hormonal markers. Here is how it compares to other commonly tested hormones:
| Test | Hormone Measured | Cycle Timing Required | What It May Indicate |
|---|---|---|---|
| AMH | Anti-Müllerian Hormone | No (any cycle day) | Ovarian reserve / egg supply |
| FSH | Follicle-Stimulating Hormone | Yes (Day 2–3) | Ovarian function and egg quality signals |
| LH | Luteinising Hormone | Yes (variable) | Ovulation timing and hormonal balance |
| Oestradiol | Oestrogen | Yes (Day 2–3) | Ovarian activity at baseline |
AMH is frequently used for initial ovarian reserve screening in part because it does not require testing at a specific point in the menstrual cycle, which may offer practical advantages for scheduling and repeat measurements. You can explore a broader range of female hormone blood tests available at our London clinic.
How Often Should You Have an AMH Test?
There is no single universal recommendation for AMH testing frequency. However, the following general guidance may be helpful:
- One-off baseline screening is common for those wanting an initial picture of their ovarian reserve
- Annual or biennial repeat testing may be considered by those monitoring a known condition or tracking changes over time
- Pre-treatment testing is commonly requested before fertility-related procedures; a healthcare professional will advise on timing
Practical Insight: If you have had a previous AMH result, repeat testing after 12–24 months can sometimes highlight trends. Discuss the appropriate interval with a healthcare professional.

Frequently Asked Questions About AMH Testing
1. What is AMH testing for ovarian reserve?
AMH testing for ovarian reserve is a blood test that measures Anti-Müllerian Hormone, a marker produced by follicles in the ovaries. It can suggest the approximate number of eggs remaining and is widely used in clinical practice as an ovarian reserve indicator, as referenced in UK fertility guidelines. It does not require specific cycle timing and is a commonly used starting point for ovarian reserve assessment.
2. Does a low AMH result mean I cannot conceive?
No. A low AMH result does not confirm infertility or mean that conception is impossible. It may suggest that ovarian reserve is lower than average for your age, which can be a useful starting point for a conversation with a fertility healthcare professional. Conception depends on many factors beyond AMH alone.
3. Can I have an AMH test at any time during my menstrual cycle?
Yes. One of the practical advantages of AMH testing is that it does not need to be taken on a specific day of your menstrual cycle, unlike FSH or oestradiol tests. This may offer greater scheduling flexibility at a walk-in clinic.
4. What can cause a high AMH result?
A high AMH result may sometimes be associated with polycystic ovary syndrome (PCOS), a condition in which the ovaries contain a higher than typical number of small follicles. High AMH can also simply reflect a naturally higher ovarian reserve in younger individuals. A high result should be reviewed in context by a healthcare professional.
5. How long does it take to get AMH test results in London?
At Walk-in Clinic London, AMH blood test results are typically available within a few working days. Results are communicated clearly, and you will receive a written report that you can share with your healthcare provider for further discussion.
6. Is AMH testing suitable for those who have had cancer treatment?
AMH testing may be useful for individuals who have undergone chemotherapy or radiotherapy, as these treatments can sometimes affect ovarian function. Testing may help to indicate whether ovarian reserve has been impacted. It is advisable to discuss the timing and interpretation of results with a healthcare professional familiar with your history.
7. Does age affect AMH levels?
Yes. AMH levels naturally decline with age as ovarian reserve decreases over time. This is a normal biological process. Reference ranges are typically age-adjusted, which means a result that appears low in isolation may still be considered appropriate for someone in their late thirties or forties.
8. Does Walk-in Clinic London offer treatment or fertility consultations?
No. Walk-in Clinic London is a nurse-led testing and screening service. We provide professional blood sample collection and laboratory-reported results only. We do not offer prescriptions, treatment plans, or specialist fertility consultations. Results should be discussed with a qualified healthcare professional.
9. Can AMH testing help me decide about egg freezing?
An AMH result can provide useful background information if you are considering egg freezing, as it may indicate where your ovarian reserve currently sits. However, decisions around egg freezing should be made in consultation with a fertility specialist, who will consider AMH alongside other clinical and personal factors.
10. Is AMH testing available without a GP referral in London?
Yes. Private AMH testing at Walk-in Clinic London does not require a GP referral. You can book directly or walk in at a time that suits you. Your results report can then be shared with your GP or any healthcare professional of your choosing.
