NICE’s NG23 guidance, last updated on 15 April 2026, says women aged 45 and over with menopausal symptoms are usually diagnosed from symptoms and menstrual change, not a hormone panel. HerStack’s hormone-testing guidance uses that pathway, and blood tests are mainly for younger women or for cases where another diagnosis needs ruling out.

What is the best evidence-based perimenopause testing pathway in the UK?
The British Menopause Society, established in 1989, sets out a simple rule: if you are 45 or over and have menopausal symptoms, diagnose perimenopause or menopause from symptoms alone unless there is uncertainty or another pathology to suspect. NICE’s NG23 guidance mirrors that rule, and BMS standards say FSH and estradiol should not be used routinely because they do not track symptom severity or treatment need.
The BMS says the average menopause age in the UK is 51, the normal range is 45 to 55, more than 75% of women experience menopausal symptoms, around a quarter describe them as severe, and roughly a third report long-term symptoms. If you are under 45, the pathway changes: NICE and NHS guidance allow serum FSH to be used selectively, especially if you are 40 to 45 with symptoms and not using combined hormonal contraception or HRT, and if POI is suspected under 40, specialist assessment should be arranged.
Which test or kit is worth paying for?
A private test only earns its keep if it changes what happens next. If you already meet the clinical criteria for perimenopause, the NHS GP review is usually the better first step, because it is free and it can pick up non-menopause causes of fatigue, bleeding or amenorrhoea. The commercial market is useful when you need speed, specialist review or a narrower question answered, not when a symptom-led diagnosis is already clear.
| Test/kit | What it measures | Price | When it’s worth it | Next step |
|---|---|---|---|---|
| NHS GP review | Symptoms, cycle changes, contraception, bleeding pattern, medication use, pregnancy or other causes | Free | First step for most women over 45 with typical symptoms | Diagnose clinically or order targeted tests only if the picture is not typical. |
| Targeted serum FSH | Ovarian signalling, sometimes repeated 4 to 6 weeks apart | Free on NHS when indicated; private prices vary | Useful if you are 40 to 45, or under 40 with suspected POI, and not on combined hormonal contraception or HRT | Repeat and refer if diagnosis remains uncertain. |
| The London Clinic perimenopause assessment | Hormone profiling, bone health assessments, thyroid checks and other markers | £535 | If you want a bundled private assessment with GP review and rapid results | Review results with the clinician, but do not let one test overrule symptoms. |
| Hertility Advanced At-Home Hormone and Fertility Test | Tailored panel of up to 10 hormones, with a doctor-written report and care plan | From £249 | If you are under 45, want fertility context, or want a private test plus results call | Use the report with a clinician, then go back to the NHS if bleeding or red flags need a different work-up. |
| My Menopause Centre consultation plus tests | Consultation-led testing arranged through Medichecks, with venous, home venous or finger-prick options | Doctor £290, nurse £190; tests extra | If you want menopause-expert review before choosing a blood test | Use the consultation to decide whether testing is actually needed. |
My Menopause Centre says finger-prick testing is not usually recommended for hormone testing. Newson Clinic was founded in 2018 by Dr Louise Newson and Dr Rebecca Lewis. Menopause Care is led by Dr Naomi Potter.
When should the GP do something other than a menopause diagnosis?
Use the GP pathway, not a menopause kit, if you are under 45, if your symptoms are atypical, if you are on combined hormonal contraception or HRT, or if bleeding is the main problem. NICE CKS advises a detailed history that includes pregnancy and menorrhagia, and its fatigue guidance supports basic checks when clinically indicated, including blood tests, a urine pregnancy test and urinalysis. For amenorrhoea and cycle disruption, thyroid disease, prolactin problems and PCOS belong in the differential.
A single hormone number can mislead. The BMS says FSH fluctuates and does not correlate with symptom severity or duration, and its estradiol guidance says a single serum oestradiol cannot separate endogenous from exogenous hormone exposure in perimenopause. If you have irregular bleeding, especially after 12 months without a period, treat that as a bleeding pathway, not a menopause-testing pathway; NICE classifies postmenopausal bleeding as unexplained bleeding more than 12 months after menstruation has stopped.
What should you do next on HerStack?
HerStack’s hormone-testing guidance and care pathway are built for the step most readers actually need: deciding whether symptoms fit the clinical picture, whether a GP review is enough, or whether a private specialist assessment is worth paying for. HerStack’s concern-finder is the practical route if you want a quick read on where you sit before you book anything.
If you are 45 or over with classic symptoms, start with the NHS. If you are under 45, ask for targeted testing rather than a broad panel. If you want a private route, choose one that gives clinician review, not just a lab result.
Frequently Asked Questions
Are at-home hormone tests worth it in the UK?
Only when the result will change what you do next. NICE and the British Menopause Society say women aged 45 and over with typical symptoms usually do not need confirmatory blood tests. At-home tests are more useful if you are under 45, suspect POI, or need a fertility-focused assessment from providers such as Hertility, Medichecks or My Menopause Centre.
How much does a private perimenopause blood test cost in the UK?
In practice, simple private panels sit roughly in the £50 to £200 band, with Medichecks’ advanced female hormone blood test at £99. More comprehensive clinician-led packages cost more, such as Hertility’s at-home test from £249 and The London Clinic’s perimenopause assessment at £535. Compare that with a free NHS GP review first, because that is often the better first step.
Which blood tests matter for fatigue in perimenopause?
Do not assume hormones are the answer. NICE CKS on fatigue points first to a fuller work-up, which can include blood tests, a urine pregnancy test and urinalysis, and NICE guidance on amenorrhoea and PCOS flags thyroid disease, prolactin and pregnancy as alternative causes. In practical terms, ferritin, thyroid function, vitamin D and B12 are the usual checks before anyone spends on a menopause panel.
