If you're 45 or over with typical symptoms, you usually don't need a perimenopause test at all. UK guidance says a clinician can recognise perimenopause from your symptoms and your periods alone (NICE NG23).
Blood tests do have a role for some people, mainly if you're under 45. This guide explains when a test helps, when it doesn't, and why home kits are a poor guide.
If you're not sure whether your symptoms fit, our perimenopause symptom checklist can help you pull them together before an appointment.
Key takeaways
- Over 45 with typical symptoms? NICE says perimenopause is identified without laboratory tests (NICE NG23).
- An FSH blood test may be used if you're aged 40 to 45 with symptoms, or under 40 if menopause is suspected (NICE NG23).
- The Royal College of Obstetricians and Gynaecologists does not recommend over-the-counter menopause tests (RCOG, 2022).
- A symptom diary is often more useful to your GP than a test result.
Is there a test for perimenopause?
There's no single test that confirms perimenopause. Your hormone levels rise and fall a lot during this time, often from week to week. So one result can look "normal" even when you're clearly in the transition.
That's why NICE guidance focuses on symptoms. If you're an otherwise healthy woman aged 45 or over, perimenopause is identified when you have hot flushes or night sweats that have recently started, plus any change in your menstrual cycle (NICE NG23). Menopause is identified when you haven't had a period for at least 12 months and aren't using hormonal contraception.
For this age group, NICE advises against using tests such as anti-Müllerian hormone (AMH), inhibin, oestrogen levels, antral follicle count or ovarian volume to identify perimenopause or menopause (NICE NG23). Some private "menopause blood test" panels include these markers, so it's worth knowing they aren't recommended for this purpose.
When is a menopause blood test used?
Blood tests are mainly for younger women, or where the picture isn't clear. The main test is follicle-stimulating hormone (FSH).
| Your situation | What UK guidance says |
|---|---|
| 45 or over, with typical symptoms | Identified from symptoms. No blood test needed (NICE NG23) |
| Aged 40 to 45, with symptoms including a change in your cycle | An FSH test may be used (NICE NG23) |
| Under 40, where menopause is suspected | An FSH test may be used. Premature ovarian insufficiency is diagnosed on raised FSH in 2 samples taken 4 to 6 weeks apart, never on a single test (NICE NG23) |
| Using combined hormonal contraception or high-dose progestogen | FSH shouldn't be used to identify menopause, as these hormones affect the result (NICE NG23) |
Your GP may also suggest other blood tests if your symptoms could have another cause, such as a thyroid problem. That's about ruling things out, not confirming perimenopause.
If you're under 45 and think you have menopause symptoms, the NHS advises seeing a GP (NHS). Our guide to menopause age explains early menopause in more detail.
Do menopause test kits work?
Home menopause test kits usually measure FSH in a urine sample. The Royal College of Obstetricians and Gynaecologists says it does not recommend these over-the-counter tests, because they aren't a good way of detecting menopause or perimenopause (RCOG, 2022).
The reasons are practical:
- FSH goes up and down through your cycle and during the menopause transition. A single reading is a snapshot.
- A negative result doesn't rule it out. You can still be perimenopausal with a normal reading.
- Hormonal contraception makes the test meaningless, because it suppresses FSH.
The RCOG advises speaking to a healthcare professional if you think you might be going through the menopause, rather than buying a test (RCOG, 2022).
Is there a "best" menopause test kit?
This is the most common follow-up question, and the honest answer is that the comparison matters less than people expect. The kits sold in UK pharmacies and online — whatever the brand — overwhelmingly measure the same thing in the same way: FSH in urine, read against a threshold. They share the same limitation, so choosing a more expensive one does not solve it.
A few distinctions are worth knowing:
| Type | What it measures | The catch |
|---|---|---|
| Urine FSH kit (most pharmacy kits) | FSH in urine, as a positive/negative | FSH swings through the cycle; a negative does not rule perimenopause out |
| Home finger-prick blood kit | FSH, sometimes oestradiol, as a number | More precise number, same interpretation problem |
| Private blood panel | FSH, oestradiol, often thyroid | Useful under 45; rarely changes anything over 45 |
If you are over 45 and having symptoms, none of these is likely to tell you something your symptoms have not already. That is not a knock on the manufacturers — it is what the hormone does during the transition.
When a blood test genuinely is useful
The picture changes with age, and this is the part that gets lost in the "tests don't work" headline.
- Over 45 with typical symptoms — a diagnosis is usually made on symptoms and cycle pattern. A test rarely adds anything.
- Aged 40 to 45 — a blood test is more likely to be considered, because the diagnosis is less obvious at that age.
- Under 40 — testing matters. Menopause before 40 is called premature ovarian insufficiency, and it is diagnosed with blood tests, usually FSH measured twice a few weeks apart alongside other hormones (NHS).
So "is there an early menopause test?" has a different answer from "is there a menopause test?" Under 40, yes, and it should be done properly through a clinician rather than a pharmacy kit. Our guide to menopause age, early menopause and POI covers what the thresholds mean.
How to read menopause blood test results
If you have had bloods done, these are the figures that usually appear:
- FSH — rises as the ovaries become less responsive. A persistently high FSH supports the picture, but a single high or normal reading proves little on its own, because it moves through the cycle.
- Oestradiol — the main form of oestrogen. Falls over the transition, but fluctuates considerably, sometimes rising above premenopausal levels before it drops.
- LH — often reported alongside FSH; interpreted together rather than alone.
- TSH — frequently added, because an underactive thyroid produces a strikingly similar set of symptoms and is worth ruling out.
Two practical points. Hormonal contraception suppresses FSH, so results taken on the combined pill or a hormonal coil cannot be read at face value. And if you are still having periods, the day of your cycle changes what "normal" looks like — so the date the sample was taken matters as much as the number.
The thyroid overlap is worth taking seriously rather than treating as a footnote. If you have not had thyroid function checked, our guide to getting a thyroid test in the UK explains how, and reading thyroid results covers what the numbers mean.
What to bring to your appointment instead
A clear record of your symptoms usually tells a clinician more than a kit result. Before your appointment, note:
- the dates of your last few periods, and whether they're heavier, lighter or more spaced out
- hot flushes, night sweats and sleep changes
- mood, anxiety, memory or concentration changes
- anything else new, such as joint aches, dry skin or vaginal dryness
- any contraception or hormonal treatment you use
Our guide to perimenopause symptoms lists the common signs. If you'd like to talk it through, our online menopause clinic offers GP consultations focused on menopause. Treatment options, including lifestyle changes, talking therapy and HRT, are discussed with your clinician, with the benefits and risks explained for your situation (NICE NG23).
When to see a GP
- you think you have perimenopause symptoms and want to talk about your options
- you're under 45 and think you have menopause symptoms
- your periods become heavier or more frequent
- you've had no period for 12 months and then have any vaginal bleeding. This always needs checking. See our guide to bleeding after menopause.
- you notice palpitations or changes in your heart rate
If you feel very unwell and aren't sure where to turn, contact NHS 111. In an emergency, call 999.
Honest FAQs
Can a blood test tell if I'm perimenopausal?
Not reliably on its own. If you're 45 or over with typical symptoms, NICE says no test is needed. An FSH blood test may be used if you're 40 to 45, or under 40 (NICE NG23).
Are home menopause test kits accurate?
The RCOG doesn't recommend them. FSH levels fluctuate, a negative result doesn't rule out perimenopause, and the tests don't work if you use hormonal contraception (RCOG, 2022).
What is an FSH test?
It measures follicle-stimulating hormone, which tends to rise as your ovaries slow down. Because levels vary so much during perimenopause, it's mainly used for women under 45 (NICE NG23).
Can I get tested if I'm on the pill?
FSH testing isn't used to identify menopause if you take combined hormonal contraception or high-dose progestogen, as these affect the result (NICE NG23). A clinician will assess your symptoms instead.
Is an AMH test useful for perimenopause?
For women aged 45 and over, NICE advises against using AMH to identify perimenopause or menopause (NICE NG23).
