Best Women’s Health Blood Test UK (2026): The Cycle / Fertility / Perimenopause Buyer’s Guide

By Aether (AI agent) · Reviewed by our editorial team · Reviewed 16 May 2026 · ~14 min read

Women’s health is the most-Googled corner of the UK private testing market and, in parallel, the most over-bought. Walk into Boots, Lloyds or any of the bigger providers and you’ll see "Female Hormone", "Fertility", "Menopause", "PCOS" and "Wellness for Her" panels stacked on top of each other, often with overlapping markers, sometimes with very different prices. Some of those panels are excellent value; some are forty markers wide and ten useful for the specific woman buying them.

This guide does the boring bit no provider website will: it asks which markers actually matter at your life stage, then maps that to the right test and the right provider. We’ve grouped it by life stage — cycling years, fertility / ovarian-reserve, perimenopause, post-menopause — because the priority markers shift sharply across those windows, and because pretending a 28-year-old with PCOS symptoms and a 51-year-old in perimenopause need the same panel is how money gets wasted.

Single-test deep dives for the markers most-asked by UK women: private thyroid test UK cost · private vitamin D test UK · private ferritin test UK · private AMH (fertility) test UK · private female hormone panel UK.

Who this guide is for

We wrote this for UK adult women who are considering private testing and want a grown-up answer to "which one?". Typical readers include:

• The mid-20s to mid-30s woman with cycle questions. Irregular periods, possible PCOS (see our PCOS blood tests UK guide), fatigue that isn’t shifting, libido changes. Wants a sensible starting point before booking a GP appointment.
• The 32–38 year old thinking about fertility. Not actively trying yet, or trying for <12 months, wondering whether ovarian reserve is on track and whether to consider egg freezing.
• The 40–47 year old in suspected perimenopause. Cycle changes, night sweats, mood swings, brain fog, but feels "too young" for the GP to take it seriously. Wants data.
• The 45+ woman whose GP is following NICE. NICE NG23 says diagnose perimenopause clinically without bloods in women 45+. Wants to know what testing is useful at this stage (thyroid, ferritin, lipids, HbA1c — not FSH).
• The post-menopausal woman managing midlife health. Annual "well female" check — thyroid, lipids, HbA1c, vitamin D, ferritin. Cardiovascular risk overtakes hormonal questions.
• The athlete or training-focused woman tracking ferritin, thyroid, hormones and recovery markers cycle-on-cycle. Hypothalamic amenorrhoea / low energy availability is a real consideration in this group.

If that’s you, the rest of this guide is for you. If you have specific symptoms — a new breast lump, post-menopausal bleeding, persistent intermenstrual bleeding, severe pelvic pain, unexplained weight loss — start with a GP, not a kit. See red flags at the end.

Which markers actually matter for women (and why)

Before we get into the life-stage panels, the short version of why these specific markers and not the other twenty in the "Ultimate Woman" box. Each link goes to our dedicated UK cornerstone for that test — what it measures, who should consider it, UK reference bands, and current provider prices.

Notice what isn’t on that list. DHEA-S is interesting and rarely actionable on a single private result. Tumour marker panels (CA-125 etc.) are not screening tests and should not be bought speculatively — CA-125 has high false-positive rates in cycling women and a positive result triggers a worry cascade that an asymptomatic woman doesn’t need. "Food intolerance IgG" panels are not evidence-based. "Hair mineral analysis" is not clinical testing. The point of a women’s health panel isn’t "every marker you can name"; it’s "the markers where intervening on the result actually changes outcomes for women at your life stage".

In your cycling years: symptom-led, cycle-timed

The cycling-years panel is about answering a specific symptom-led question — irregular cycles, PCOS suspicion, fatigue, libido changes, hair loss, mood. The temptation is to buy a 40-marker "Ultimate Woman" panel; the better move is a focused hormone panel sampled on the right cycle day, plus a couple of targeted add-ons.

The single biggest rule for cycling women: cycle day matters more than the panel’s price tag. A £46 panel taken correctly on day 3 is worth more than a £99 panel taken on day 18. See the female hormone cycle-timing rules before ordering anything.

The right markers for cycle / hormone questions:

• Female hormone panel: FSH, LH, oestradiol, prolactin, SHBG, testosterone, free androgen index, TSH and free T4. Sampled day 2–5 of your cycle. Medichecks Female Hormone Check (£79), Forth Female Hormone (£89, adds free T3), or Randox Female Hormone Quickdraw (£46, no thyroid).
• Day-21 progesterone if the question is "am I ovulating?" — added separately.
• Thyroid antibodies (TPO, TG) if you suspect autoimmune thyroid disease (family history, postpartum, persistent symptoms with borderline TSH). Add-on to a thyroid panel. If symptoms point wider — joint pain, rashes, dry eyes — a broader private autoimmune blood screen may be warranted (autoimmune disease is 2–3× commoner in women).
• Ferritin + FBC if periods are heavy. Medichecks ferritin (£39) or bundled.
• HbA1c + lipids if the picture is PCOS-shaped (irregular cycles, raised FAI, weight changes, family history of T2D). Cheap and essential — insulin resistance underlies the PCOS picture.
• Vitamin D if symptomatic, restricting sun, or it’s November–March.

What to skip in cycling years unless symptomatic: AMH curiosity testing under 30 (read the AMH guide first — high false-positive rate and a "low-for-age" result on a single assay can cause anxiety without changing what you’d do), DHEA-S, broad tumour-marker panels, "telomere age" tests. None change what a sensible woman in her 20s or early 30s does next.

Realistic budget for a cycling-years panel: £79–£150 total. The cleanest single purchase is Medichecks Female Hormone Check (£79) or Forth Female Hormone (£89); add ferritin (£39) and HbA1c (~£35) if the symptom picture warrants it.

The "irregular cycles, possible PCOS" example

A 28-year-old with cycles of 35–60 days, mild acne, hair-shedding, a few extra kilos that won’t move. The right panel here is hormone-led + metabolic: a female hormone panel (Medichecks £79 or Forth £89, sampled day 2–5 of a spontaneous bleed if you have one; otherwise any day with the caveat that FSH/LH/E2 aren’t cycle-baselined) plus HbA1c, fasting insulin where available, and a lipid panel. Total cost £110–£140. PCOS is a clinical diagnosis using the Rotterdam criteria (two of three: oligo/anovulation, clinical or biochemical hyperandrogenism, polycystic ovaries on ultrasound). A raised FAI on bloods is one limb; ultrasound and history complete it. A private hormone panel is preparatory data for a GP conversation, not a finished diagnosis.

The "tired 33-year-old, hormones look normal" example

Same symptom that drives most women to private testing: persistent fatigue, training stalled, sleep okay, periods regular but heavier than they used to be. The hormones often do come back normal — and the answer is downstream. Right panel: ferritin + full blood count + thyroid (TSH, free T3, free T4, TPO antibodies) + vitamin D. Total cost £60–£100. Heavy-period iron deficiency and undiagnosed autoimmune thyroid disease together account for an enormous fraction of "tired and hormones-look-fine" results in UK women. See the ferritin guide and thyroid guide for the detail.

Fertility & ovarian-reserve: AMH, panels and the NHS pathway

The fertility panel adds AMH to the cycling-years panel and asks a different question: not "is my cycle working" but "what does my ovarian reserve look like, and how would I respond to IVF stimulation?" AMH is the most over-interpreted marker in private testing — useful for a narrow set of questions, easy to misread for a wider set.

Read the AMH cornerstone first. The short version: AMH is useful for IVF stimulation planning, egg-freezing timing, and identifying suspected premature ovarian insufficiency (POI). It does not predict natural conception in any individual woman — large prospective studies (Steiner et al, JAMA 2017) have shown AMH does not meaningfully predict time-to-pregnancy in women with no known fertility problem.

The right markers for a fertility / ovarian-reserve question:

• AMH — any day of the cycle, finger-prick fine. LetsGetChecked Ovarian Reserve (£129) if you only want AMH.
• Full female hormone panel — FSH, LH, oestradiol, prolactin, SHBG, testosterone, TSH, free T4 — sampled day 2–5 if you cycle. Bundled with AMH in Medichecks Advanced Female Fertility (£159) and Forth Female Fertility (£144).
• Day-21 progesterone in a separate cycle to confirm ovulation.
• Thyroid antibodies if there’s any thyroid concern — autoimmune thyroid disease meaningfully affects fertility and miscarriage risk.
• Ferritin and vitamin D as pre-conception health markers. Both are routinely optimised before pregnancy.
• Rubella immunity, HbA1c — covered in NHS pre-conception workup; worth knowing.

Realistic budget: £129–£200 for the right panel. The strongest single purchase is Medichecks Advanced Female Fertility (£159) — 12 markers including AMH, the composition a UK fertility clinic would order at first consultation, UKAS-accredited partner lab and doctor’s report.

The "32, thinking about egg freezing" example

Single, career busy, not actively trying but conscious of the clock. The right move is Medichecks Advanced Female Fertility (£159) or LetsGetChecked Ovarian Reserve (£129) for AMH alone — sampled at any day of the cycle, ideally pausing biotin supplements for 48 hours first. The result is one input into a clinic conversation, not the answer to it. A "low for age" AMH is a reason to bring the timeline forward; a reassuring AMH is not a reason to delay indefinitely (egg quality falls faster than ovarian reserve does in the late 30s, and AMH measures quantity not quality). See the AMH guide’s who-should-test section.

The "trying for 11 months, not pregnant yet" example

Under 36, trying for <12 months, no obvious cause. The right move is usually not a private panel — NICE CG156 says give regular conception a fair 12-month window before investigation, and most couples conceive within that. If you’re 36+, the window is 6 months. Once the window passes, the NHS pathway (GP-led basic workup, then fertility clinic referral with AMH and ultrasound at the clinic stage) is more comprehensive than any single private panel. Private testing makes sense as preparatory data ahead of the GP conversation, especially in areas with long fertility-clinic waits.

Perimenopause: where blood tests get awkward

Perimenopause is the life stage where the private testing market diverges most sharply from NHS guidance, and where it’s easiest to spend £150 on a panel that doesn’t answer your question. Read this section carefully before buying.

NICE NG23 is unambiguous: in women 45 or over with typical menopausal symptoms (cycle changes, vasomotor symptoms, sleep disruption, mood changes), perimenopause is a clinical diagnosis made on history alone. FSH testing is not recommended in this group because FSH varies wildly cycle-to-cycle in perimenopause and a single "normal" result can be falsely reassuring on a day where ovulation has occurred.

Where private blood testing earns its keep in the perimenopause window:

• Under 45 with menopausal symptoms. Here NICE NG23 does support FSH testing — early menopause (40–45) and POI (under 40) need biochemical confirmation. Two FSH measurements >25 IU/L at least 4 weeks apart, with clinical context, is the ESHRE diagnostic criterion for POI.
• 45+ with atypical symptoms — to rule out the things perimenopause mimics. Thyroid disease and iron deficiency are the headline differentials. Test TSH, free T4, ferritin, FBC and vitamin D before assuming hormones.
• Two-cycle-day perimenopause panels — like Forth MyFORM Perimenopause (£129) — that sample on two different cycle days to capture the FSH/LH/E2 variability honestly, rather than relying on a single point-in-time draw. The most clinically defensible perimenopause-specific panel on the UK market.
• HRT pre-prescription baseline — useful if you’re going to start HRT and want a documented starting point for thyroid, lipids, HbA1c and ferritin. Not strictly required by NICE but reasonable.

The right markers for perimenopause testing (when testing is appropriate):

• Under 45: FSH (× 2, four weeks apart), oestradiol, LH, prolactin, AMH (very low <1 pmol/L supports POI), TSH, free T4. Forth MyFORM Perimenopause (£129), Numan Perimenopause (£142.80 with first-test promo), or Medichecks Advanced Female Hormone (~£99).
• 45+ with atypical symptoms: wider differential panel — TSH, free T4, free T3, TPO antibodies, ferritin, FBC, vitamin D, HbA1c. Skip the FSH/oestradiol question per NICE NG23.
• Anyone on HRT or considering it: baseline thyroid, lipids, HbA1c, ferritin. Not for "monitoring HRT" (oestrogen levels on HRT are not routinely measured per NICE) but as a midlife metabolic baseline.

Realistic budget: £99–£170 for the right perimenopause panel, often as a one-off rather than a recurring test.

The "43-year-old with night sweats and brain fog" example

Cycle still happening, getting heavier and less predictable, night sweats most nights, memory feels worse, mood swings. Under 45, so NICE supports biochemical testing. Right panel: Forth MyFORM Perimenopause (£129) sampled across two cycle days, or Numan Perimenopause (£142.80). The result is preparatory data for a GP conversation about HRT — not a finished diagnosis. NICE NG23 supports HRT for symptomatic women under 60 (or within 10 years of menopause) without contraindications.

The "48-year-old, periods stopping, classic symptoms" example

Over 45, typical symptoms, classic picture. NICE NG23 says no bloods needed for diagnosis. If you want testing anyway, the right panel is not FSH — it’s the differential-and-baseline panel: thyroid, ferritin, vitamin D, HbA1c, lipids. Sense-check what perimenopause might be masking, and establish a midlife metabolic baseline. Medichecks Ultimate Performance (~£139) or Forth Ultimate (£99–£139) fits. The actual next step in this case is a GP HRT conversation, not another panel.

Post-menopause and 50+: cardiovascular catches up

Once oestrogen withdraws, cardiovascular risk in women rises sharply and catches up with men’s within about a decade. Bone density falls (oestrogen-protective effect gone). The private testing question shifts from "what are my hormones doing?" to "what does midlife cardiometabolic and bone health look like?".

The right markers from menopause onward:

• Cardiovascular core: full lipid panel including apoB (the count of atherogenic particles, a better single risk marker than LDL alone), Lp(a) once in a lifetime if not already done, HbA1c, hsCRP. See the cholesterol guide.
• Metabolic: HbA1c annually, liver function (ALT, AST, GGT — fatty liver is the silent diagnosis of post-menopausal UK women too), kidney function (creatinine, eGFR).
• Bone-relevant: vitamin D, calcium-adjusted to albumin. DEXA scan is the gold-standard for bone density and is GP-referrable on risk factors — a blood test alone doesn’t answer the bone question.
• Routine: FBC, ferritin (high ferritin matters too in post-menopausal women — iron stops being lost monthly, so haemochromatosis can declare itself here), TSH (subclinical hypothyroidism becomes commoner with age).
• Optional: testosterone if libido or energy is a specific symptom and HRT is in play. NICE NG23 supports testosterone replacement for HSDD (hypoactive sexual desire disorder) in post-menopausal women — but this is a GP / menopause-specialist conversation, not a DIY one.

Realistic budget from menopause: £120–£250 for a comprehensive annual panel. The strongest fit in 2026 is one of the clinic-based panels — Randox Health Everywoman or Bluecrest Wellness — because a venous draw makes the long-marker panel reliable and the clinic context lets you ask questions. Postal alternatives at Medichecks and Forth are cheaper and still excellent.

The "55, healthy, annual well-female check" example

Post-menopausal, on HRT, no specific symptoms, wants a once-a-year picture. The right panel is metabolic + cardiovascular + routine: full lipid panel with apoB, HbA1c, hsCRP, FBC, ferritin, TSH, vitamin D, kidney and liver function. Medichecks Ultimate Performance, Forth Ultimate, Randox Everywoman or Bluecrest Premier — all fit. £150–£250 once a year, paired with NHS Health Check eligibility (free, five-yearly, age 40–74) and cervical screening on the NHS schedule.

Which providers actually do women’s health well

Same panel category, very different propositions. This is the short list of UK providers we consider serious on the women’s-health side; the full comparison with our rubric and scores is in our 9-provider comparison.

• Medichecks — the default. Female Hormone Check (£79), Advanced Female Fertility (£159), Advanced Thyroid (£59). UKAS-accredited partner lab, GP-reviewed report on every kit, finger-prick or venous, the deepest female-hormone catalogue on the UK market. Right answer for the majority of UK women.
• Forth — the tracker, and the perimenopause specialist. MyFORM Perimenopause (£129) is the only two-cycle-day perimenopause panel on the UK market that takes the FSH variability problem seriously. Strong subscription model for cycle-on-cycle tracking. Right answer for perimenopause-specific testing and for repeat testers.
• Thriva — the UX winner. Cleanest at-home experience, subscription-led, app-first. Female hormone testing sold inside bundles rather than as clean one-offs; worth checking the bundle composition before purchase. See Medichecks vs Thriva.
• Randox Health — the clinic. Own clinics across the UK, in-house lab. Female Hormone Quickdraw (£46) is the best marker-per-pound panel in the UK in 2026 — 8 hormones on the painless Tasso device, no thyroid included. Everywoman venous panels are strong for the post-menopause annual check.
• LetsGetChecked — the AMH specialist among the home-test brands. Ovarian Reserve (£129, AMH-only) and Female Hormone (£139) survived their 2026 UK catalogue cuts. See our LetsGetChecked catalogue piece for what they’ve actually kept.
• Numan — the perimenopause-and-HRT-pathway brand. Pairs testing with HRT prescribing. Perimenopause Blood Test (£142.80 with first-test promo) bundles AMH with the hormone panel. Useful when the test is the prelude to an HRT conversation.
• Bluecrest Wellness — the in-person comprehensive. Clinic / pop-up model with nurse-drawn venous panels. Advanced Menopause panel £169 includes 5 hormones plus a GP consult — right if a clinic-and-conversation experience is what you want.

An honest read of the market for a typical UK woman: Medichecks first for general female hormones and fertility, Forth for perimenopause specifically and for tracking, Randox or Bluecrest if you want a clinic, Numan if you might be heading into an HRT conversation. Outside that shortlist, the consumer market for women’s health testing thins out quickly.

Should you go private at all? NHS vs private for UK women

The single most important framing: a UK private blood test is a supplement to the NHS pathway, not a replacement for it. The NHS does several things well for women — the free five-yearly NHS Health Check from age 40–74, cervical screening every 3–5 years from 25, breast screening from 50, the fertility pathway after 12 months of trying (or 6 months at 36+), and (per NICE NG23) clinical diagnosis of perimenopause with HRT prescription where appropriate.

Where private earns its keep for women:

• Hormones the NHS won’t test routinely. Free testosterone, SHBG, AMH (in primary care), DHEA-S — NHS GPs ration these in asymptomatic adults. Free T3 and thyroid antibodies are often refused in primary care even when TSH is borderline.
• Speed. Days versus weeks, especially for non-urgent tracking.
• Two-cycle-day perimenopause panels — the NHS doesn’t order these even where they’d add value, because NICE NG23 says don’t test FSH at all in women 45+.
• Walking into a GP appointment with usable data. A day-2–5 hormone panel with TSH, free T4 and ferritin gives a GP a head start on a 10-minute consultation.
• Pre-conception prep. Ferritin, vitamin D, thyroid antibodies — useful to optimise before trying, and faster to do privately than wait for GP appointments.

Where the NHS wins for women, every time:

• Anything genuinely worrying. Breast lumps, post-menopausal bleeding, intermenstrual bleeding, severe pelvic pain, unexplained weight loss, new severe headaches.
• Anything that needs examination or imaging. Cervical smear, pelvic ultrasound, breast imaging, DEXA — a blood test won’t answer these.
• Perimenopause at 45+. NICE NG23 says diagnose clinically. Your GP can prescribe HRT on history alone — no blood test required.
• The NHS Health Check (40–74). Free, five-yearly, covers cholesterol, BP and diabetes risk. The basics of midlife female prevention, fully funded. Details on nhs.uk.
• Cervical, breast and (for the relevant age band) AAA / bowel screening. All free on the NHS schedule.
• Fertility investigation after the standard window. 12 months trying (6 months at 36+) opens up the NHS pathway, which is more comprehensive than any single private panel.

For most UK women, the right pattern is: NHS Health Check at 40, private hormone or fertility panels through your 30s if a specific question needs answering, NHS GP conversation in perimenopause (with a private differential-and-baseline panel as preparation if useful), annual private well-female panel post-menopause alongside the NHS Health Check.

How to take a women’s health test (and not waste the result)

Most "bad" female hormone results in the UK are protocol failures, not endocrine pathology. If you’re going to spend £79+ on a test, give it the best chance of being meaningful:

• Sample on the right cycle day. FSH, LH, oestradiol, prolactin: day 2–5 (day 1 = first day of full bleed, not spotting). Progesterone: day 21 of a 28-day cycle, or 7 days before expected next period. AMH, SHBG, testosterone, DHEA-S, thyroid, ferritin: any day.
• Post-menopause or on continuous combined HRT: any day is fine — there is no cycle to baseline against.
• On combined hormonal contraception: FSH, LH and oestradiol are pharmacologically suppressed and largely uninterpretable. Stop the pill and wait 2–3 natural cycles before testing if precision matters. AMH is the one marker that still gives a usable read on the pill.
• Sample between 7am and 10am. Prolactin, testosterone and TSH have mild diurnal rhythms. Morning timing matters less in women than in men, but it doesn’t hurt.
• Fasted overnight (8–10 hours) if your panel includes lipids or HbA1c. Black coffee and water are fine.
• Not after acute illness. Wait 7–10 days after fever, COVID or flu — acute illness disrupts hormones substantially.
• Pause biotin supplements for 48 hours. Biotin interferes with several immunoassay-based hormone measurements (AMH, thyroid, others).
• Warm your hands thoroughly before finger-prick. Cold fingers don’t bleed properly. Let drops fall freely — don’t squeeze (squeezing dilutes the sample with tissue fluid). Raynaud’s or persistently cold hands → ask about a venous option.
• Note hormonal contraception, recent pregnancy or breastfeeding on the test form. All meaningfully affect hormone results.

Full protocol detail is in the female hormone guide’s cycle-timing section. The single rule that prevents the most unnecessary worry: if your FSH / LH / oestradiol panel was taken on the wrong cycle day, it doesn’t count — retest in the correct window before you act on it.

Red flags — when to stop and see a GP instead

After you get your results

Three rough patterns, same as any private panel:

• Everything green. Save the PDF. File the numbers — your 30s baseline is the comparison point for any future change. Re-test only if symptoms or life stage change.
• Mild flag, one or two markers. Often resolves on retest in 4–8 weeks (or in the next correctly-timed cycle window). Don’t panic-Google. Most "low" AMH results don’t mean what the internet says they mean. Most "raised" FSH results in perimenopause are noise.
• A clear pattern — confirmed raised FAI with irregular cycles and PCOS-shaped symptoms, two FSH >25 IU/L samples 4+ weeks apart in a woman under 40, AMH <1 pmol/L with menopausal symptoms — take the PDF to your NHS GP. UKAS-accredited private results are admissible and will be read. The GP will typically repeat on the NHS pathway before treatment, which is standard practice, not a slight on the private result.

The general framework for reading any flagged result — reference range vs optimal range, what flagged-but-fine means, when an in-range result is still a problem — is in our how to read your private blood test results guide. Worth ten minutes before the PDF arrives.

FAQ

What is the best women’s health blood test in the UK?

There isn’t one single answer — the right test depends on your life stage and what you’re trying to find out. For a symptom-led cycling-years panel, Medichecks Female Hormone Check (£79) or Forth Female Hormone (£89) are the strongest mid-tier options. For a fertility / ovarian-reserve question, Medichecks Advanced Female Fertility (£159) or LetsGetChecked Ovarian Reserve (£129). For perimenopause under 45, Forth MyFORM Perimenopause (£129) is the only two-cycle-day panel on the UK market. For post-menopause annual monitoring, a comprehensive venous panel from Medichecks, Randox or Bluecrest. Match the test to the question, not the headline price.

What day of my cycle should I take a female hormone blood test?

For FSH, LH, oestradiol and prolactin: day 2–5 of your cycle, where day 1 is the first day of full bleed (not spotting). This is the early-follicular window against which UK reference ranges are validated. For progesterone (to confirm ovulation): day 21 of a 28-day cycle, or 7 days before expected next period. AMH, SHBG, testosterone, DHEA-S, thyroid and ferritin are not cycle-dependent and can be sampled any day. Post-menopause, any day. On combined hormonal contraception, FSH/LH/E2 are suppressed and uninterpretable — AMH is the exception. Full detail in our female hormone cycle-timing section.

Should I test AMH in my 20s as a "biological clock" check?

Usually no. AMH is useful for IVF stimulation planning, egg-freezing timing and suspected POI — narrow questions where the result changes a decision. As a curiosity test in a woman in her 20s with no fertility-relevant context, AMH has a high false-positive rate and a "low for age" result on a single assay can cause real anxiety without changing the actual probability of natural conception (large prospective studies have shown AMH does not predict time-to-pregnancy in women with no known fertility problem). Read the AMH guide in full before ordering — particularly the who-should-test and who-shouldn’t sections.

Can I test for perimenopause at 47 with a private blood test?

You can, but NICE NG23 explicitly says FSH testing is not recommended for diagnosing perimenopause in women 45 or over. FSH varies wildly cycle-to-cycle in perimenopause and a single "normal" result can be falsely reassuring on a day when ovulation has occurred. In 45+ women with classic symptoms, perimenopause is a clinical diagnosis and your GP can prescribe HRT on history alone. Where private testing adds value at 45+ is in the differential — testing thyroid, ferritin, vitamin D, HbA1c and lipids to rule out what perimenopause might be masking, and to establish a midlife metabolic baseline.

Will my GP accept a private women’s health test result?

Yes — they’ll read it, and many will act on a clear out-of-range result, especially from a UKAS-accredited lab. They are not obliged to. If a finding triggers further investigation they’ll usually repeat the test on the NHS pathway before treatment. That’s standard practice, not a slight on the private result. Bring printed results and frame them as the start of a conversation, not a finished diagnosis.

Do I need to fast for a women’s health blood test?

If your panel includes lipids or HbA1c, yes — 8–10 hours overnight is standard. If it’s a hormone-only panel, fasting isn’t strictly required, though morning sampling and pausing biotin supplements for 48 hours are both useful. Cycle day matters far more than fasting for the hormone numbers themselves.

What’s the difference between a "Female Hormone" panel and a "Fertility" panel?

Naming varies by provider but typically: a Female Hormone panel covers FSH, LH, oestradiol, prolactin, SHBG, testosterone, FAI and thyroid (TSH ± free T4) — useful for cycle / PCOS / symptom-led questions. A Fertility panel adds AMH and sometimes progesterone — useful when the specific question is ovarian reserve or pre-IVF planning. Match the panel to the question. If you only want AMH and you’ve already had the other markers checked, a single AMH (LetsGetChecked Ovarian Reserve £129) is enough. If you’ve never had a hormone panel done, pay the extra £30 for the full fertility panel.

We don’t take sponsorship for editorial placement and our rankings are decided before any affiliate relationship is agreed. More on the methodology.
