AMH Blood Test: Fertility & Ovarian Reserve Guide
Anti-Müllerian hormone, or AMH for short, is one of the most useful fertility blood tests a woman can take. It gives a snapshot of your remaining egg supply, which makes it popular with anyone trying to conceive, considering egg freezing, or just curious about their fertility timeline.
This guide covers what AMH is, who should test it, how to read the results, and what it costs privately in the UK.
What is an AMH Blood Test?
AMH is a hormone produced by the tiny follicles in your ovaries that contain eggs. The more eggs you have left, the more AMH your body produces, and the higher your blood level tends to be.
That makes AMH the closest thing we have to a count of your remaining egg supply. Doctors call this your ovarian reserve. It’s a useful marker because, unlike a simple egg count, it can be measured with an ordinary blood test.
AMH is different from other fertility hormones. FSH and LH spike and dip through your cycle, but AMH stays fairly steady, so it can be tested at any point in your menstrual cycle rather than on a specific day.
Who Should Take an AMH Test?
AMH testing makes sense if you’re trying to conceive, especially in your mid-30s or older and wanting a sense of where things stand. It’s also worth considering if you’re thinking about egg freezing, since a result showing low ovarian reserve can help you weigh up whether to act sooner.
If you’re planning fertility treatment, clinics use AMH alongside other tests to estimate how you’ll respond to stimulation. Women who’ve had surgery or treatment that might have affected their ovaries sometimes test too, and plenty test in their 20s and 30s simply to know where they are.
AMH does not test whether you can get pregnant, and it doesn’t say anything about male fertility or egg quality. It’s one piece of the fertility picture, not the whole story.
What Do AMH Results Mean?
AMH results are given in nanograms per millilitre (ng/mL) or, in some UK labs, pmol/L. The exact reference ranges vary between labs and age groups, so always read your own report’s range first. As a general ballpark:
| AMH Level (ng/mL) | What it suggests |
|---|---|
| Over 4.0 | High ovarian reserve (can be linked to PCOS) |
| 1.5 – 4.0 | Healthy, normal ovarian reserve |
| 0.7 – 1.5 | Reduced reserve for your age |
| Under 0.7 | Low ovarian reserve |
The key point is that AMH declines naturally with age. There’s a normal, expected drop every year, so a level that’s perfectly fine at 32 might be low at 40. Interpreting AMH without your age is close to meaningless.
A high AMH level isn’t automatically a good thing. It can point to polycystic ovary syndrome (PCOS), which some women find helpful to know about even if they aren’t trying to conceive.
AMH Blood Test Costs in the UK
AMH testing is widely available through private providers. A standalone AMH test ranges from about £79 to £129, while broader fertility panels cost more. Here’s how the main providers compare.

| Provider | Test | Price | Link |
|---|---|---|---|
| Medichecks | Anti-Müllerian Hormone (AMH) Blood Test | £79 | View test |
| Medichecks | Day 3 Fertility Check | £55 | View test |
| YorkTest | Female Fertility Test | £55 | View test |
| Goodbody Clinic | Female Hormone and Fertility Test | £79 | View test |
| Forth | AMH (Anti-Mullerian Hormone) Test | £99 | View test |
| Goodbody Clinic | AMH Blood Test | £109 | View test |
| Thriva | AMH Blood Test | £113 | View test |
| LetsGetChecked | Ovarian Reserve (AMH) Test | £129 | View test |
Medichecks offers the cheapest standalone AMH test at £79, with both finger-prick and clinic collection. Their Day 3 Fertility Check at £55 is a bargain if you want FSH, LH, oestradiol and AMH measured together on the right day of your cycle, and YorkTest matches that price for a Female Fertility Test that includes AMH alongside the other key markers.
Goodbody Clinic sells a broad Female Hormone and Fertility panel at £79 and a dedicated AMH test at £109. In my experience comparing these kits, the premium end doesn’t necessarily buy you a better result: Thriva and LetsGetChecked sit there with finger-prick home kits at £113 and £129 respectively.
Where you test matters less than consistency. Because AMH is useful for tracking change over time, it’s worth picking one provider and sticking with it so your results are comparable.
How to Test
Most providers offer AMH as a simple finger-prick home kit that you post back in a prepaid envelope, plus a clinic option for a venous draw. Since AMH doesn’t fluctuate through your cycle, you don’t need to time the test around your period the way you do with FSH.
Results typically arrive within a few days to about a week, depending on the provider.
What if Your AMH Is Low?
A low AMH result can feel worrying, especially if you’re planning to have children further down the line. Try to hold onto a couple of things.
First, AMH is a measure of egg quantity, not quality. Many women with a lower-than-average AMH still conceive naturally. Second, your level is strongly influenced by your age, and a number that seems low for a 38-year-old would be completely normal for a 42-year-old.
There’s no proven way to raise your AMH level. If your result is low and conceiving is on your mind, the practical next step is to talk things over with a GP or a fertility specialist, who can factor in your age, medical history and goals. If you’ve been trying for a while and your AMH is low, many women find that getting a fuller fertility assessment sooner rather than later is the most useful thing they can do.
