AMH test in Chiswick

What the test measures

Anti-Müllerian hormone (AMH) is made by the small follicles in the ovaries that hold developing eggs. Because the amount of AMH reflects how many of these follicles there are, an AMH blood test gives an estimate of your ovarian reserve. AMH naturally falls as you get older, and how quickly it falls is different for every woman.

AMH is useful, but it has clear limits. NICE fertility guidance advises that AMH should not be used to predict the chance of getting pregnant naturally, and recommends age as the first guide to that chance. The HFEA, the UK fertility regulator, notes that ovarian reserve tests give some indication of fertility but the results are not guaranteed. AMH also says nothing about egg quality. Where it helps most is in planning treatment such as IVF or egg freezing, because it predicts how the ovaries are likely to respond to stimulation medicines.

The price includes your sample taken at our Chiswick clinic, analysis at the Randox accredited laboratory, a review of your result with an Omnia practitioner, and a GP feedback report on request.

Who it is for

• You are considering egg freezing or IVF and want a starting point before seeing a fertility clinic.
• A fertility specialist has asked for a recent AMH level.
• You want to understand your ovarian reserve as part of planning ahead, knowing it is not a measure of natural fertility.
• You have irregular periods and your practitioner suggests AMH alongside other hormone tests.
• You have had pelvic surgery or chemotherapy and would like a baseline.

Understanding your result

AMH is reported in pmol/L. There is no single normal range, because levels depend strongly on age and laboratories use different testing methods. As an example, the fertility service at University Hospitals Plymouth NHS Trust groups results from below 3 pmol/L (very low), through 9 to 25 pmol/L (satisfactory), to above 40 pmol/L (high). Ranges vary between laboratories, so always read the range printed on your report.

A lower result suggests fewer remaining eggs and may mean the ovaries respond less strongly to fertility medicines. A higher result suggests more follicles and is common in polycystic ovary syndrome (PCOS, now also called PMOS). Neither result tells you whether you can or cannot conceive naturally, and NHS fertility services are clear that AMH cannot tell whether you will achieve a pregnancy. Your practitioner will explain what your level means for your plans and whether a referral to a fertility specialist would help.

Preparing for your test

AMH stays fairly stable through the menstrual cycle, so the test can be taken on any day of your cycle. You do not need to fast. Hormonal contraception can lower AMH levels, so a result taken while you use it may underestimate your ovarian reserve. If you use one, mention it when you book so your result can be read with that in mind. Please also tell us if you take high-dose biotin supplements, as biotin can affect some laboratory tests.

If you are trying to conceive or planning ahead, our Fertility panels combine AMH with reproductive and thyroid hormones. Our guide to AMH levels explained covers results in more detail, and our overview page lets you compare every blood test and price in Chiswick.

Questions

How much is an AMH test in Chiswick?

The AMH Test costs £99 at our Chiswick clinic in West London. This includes your blood sample, analysis at the Randox accredited laboratory, a review of your result with an Omnia practitioner and a GP feedback report on request. No GP referral is needed.

Can an AMH test tell me if I can get pregnant naturally?

No. NICE advises against using AMH to predict pregnancy through natural conception. A low AMH does not mean you cannot conceive, and a high AMH does not guarantee that you will.

Does it matter which day of my cycle I test?

No. AMH changes very little across the cycle, so you can book on any day that suits you.

Should I stop the pill before an AMH test?

Please do not stop contraception just for this test without speaking to your GP or prescriber. Your practitioner can interpret a result taken on hormonal contraception with that in mind, and advise whether a later retest would be useful.
