“Can I have a blood test to see if I'm menopausal?” is one of the most common questions in women's health — and the honest answer is: it depends on your age, and often the most useful tests aren't the hormone ones. This guide explains what FSH and oestradiol results actually mean, when NICE guidance says to skip hormone testing entirely, and the panel that genuinely helps. Testing at The Vesey in Sutton Coldfield starts from £32 with GP-reviewed results in 24–48 hours.
The Hormones: FSH, Oestradiol and What They Mean
FSH (follicle-stimulating hormone) rises as the ovaries wind down — the pituitary shouts louder as the ovaries respond less. Persistently raised FSH (typically above 25–30 IU/L) supports a diagnosis of menopause. The catch: during perimenopause FSH fluctuates wildly, swinging from menopausal to premenopausal levels within weeks. One normal FSH proves nothing; even one raised FSH isn't definitive mid-transition.
Oestradiol (the main oestrogen) falls across the transition but fluctuates the same way, and levels don't correlate well with symptoms. LH rises alongside FSH; AMH (anti-Müllerian hormone) reflects ovarian reserve and falls earlier and more steadily — useful in fertility contexts and under-40s assessment, less so for routine menopause diagnosis.
If you're taking the combined pill or HRT, hormone results are largely uninterpretable — the medication is setting the levels the test measures.
When Testing Helps — and When It Doesn't
Over 45 with typical symptoms: NICE guidance is not to use hormone tests — perimenopause and menopause are diagnosed on the pattern of symptoms and periods. A clinic charging you for FSH here is testing for the invoice, not the answer.
Age 40–45 with symptoms: testing becomes reasonable to support the diagnosis. Under 40: testing is essential — two raised FSH results 4–6 weeks apart underpin a diagnosis of premature ovarian insufficiency, which needs prompt treatment to protect bones and heart. After hysterectomy (ovaries retained) or on hormonal contraception that masks periods, FSH can also help clarify where you are.
The tests that help at any age are the exclusion panel: thyroid function (hypothyroidism mimics perimenopause almost symptom for symptom), ferritin, B12, vitamin D and HbA1c. A surprising share of 'perimenopause' turns out to be thyroid disease or iron deficiency — or both at once, since they coexist happily.
Getting Tested Properly at The Vesey
Our approach: a female hormone profile (FSH, LH, oestradiol, with AMH, testosterone or prolactin where indicated) combined with the exclusion panel — one blood draw, results in 24–48 hours, individual tests from £32. Timing matters: if you still have cycles, FSH is conventionally drawn on day 2–5, and we'll advise on medication effects before you book.
The difference from mail-order kits is the review: results are interpreted by a GP alongside your history, and lead directly to a plan — HRT where appropriate, treatment of whatever the exclusion panel found, or targeted follow-up. Women's health GP appointments (30 minutes) are from £90, 7 days a week. Book online or call 0121 387 3727.

Frequently Asked Questions
What FSH level indicates menopause?
Persistently raised FSH — typically above 25–30 IU/L on two samples taken 4–6 weeks apart — supports a menopause diagnosis. During perimenopause FSH fluctuates dramatically, so a single result in either direction is not conclusive, and testing on the combined pill or HRT is largely uninterpretable.
Why won't my doctor do a menopause blood test if I'm over 45?
Because NICE guidance says not to: over 45 with typical symptoms, hormone results fluctuate too much to add anything to a clinical diagnosis. Testing effort is better spent excluding mimics — thyroid disease, iron deficiency, low B12 or vitamin D, and raised HbA1c.
What blood tests should I have for suspected perimenopause?
Under 45: FSH (repeated), plus thyroid, ferritin, B12, vitamin D and HbA1c. Over 45: usually just the exclusion panel, as the diagnosis is clinical. At The Vesey these run from £32 per test as a single blood draw with GP-reviewed results in 24–48 hours.
Can I get a menopause blood test without seeing a doctor first?
Yes — you can book blood tests directly at The Vesey without a referral. That said, results are far more useful reviewed alongside your history, so we pair panels with a GP review; a 30-minute women's health appointment is £90 and usually available the same week.
