If you’re over 45 and have typical symptoms such as hot flushes, night sweats and changing periods, you probably don’t need a blood test to be diagnosed. NICE guidance says perimenopause and menopause in this age group should be diagnosed on symptoms alone. Hormone levels swing so much during perimenopause that one result can be misleading.
Testing is a different matter if you’re younger, if your symptoms are unclear, or if something else might be going on. That’s when a menopause test earns its place.
| Your situation | What NICE says | What it means for you |
| Under 40 with symptoms | Measure FSH, as premature ovarian insufficiency is possible | See your GP promptly; a private test can speed up the first step |
| 40 to 45 with symptoms and cycle changes | An FSH test may be considered | A private FSH-based test is reasonable |
| Over 45 with typical symptoms | Diagnose without blood tests | A test usually isn’t needed; talk to your GP about treatment |
| Symptoms that could have another cause | Rule out other conditions | Consider thyroid or iron tests as well |
Tiredness, low mood, palpitations and heavy periods can all overlap with thyroid problems or anaemia. A thyroid function test is often a sensible addition when the picture isn’t clear.
Menopause blood tests usually focus on:

Many people search for a perimenopause test, but no blood test can confirm perimenopause reliably. During perimenopause, FSH and oestradiol can rise and fall from week to week, so a result may look normal even when symptoms are clearly hormonal. Home perimenopause test kits that check FSH in urine have the same problem. They can show a raised level on one day, but they can’t tell you where you are in the transition.
For most people over 45, your symptoms and cycle changes are the best guide. A blood test helps most when you’re under 45 or when another cause needs ruling out.
Blood tests are useful in the right situation, but they have real limits:
If your symptoms are affecting daily life, you don’t need a blood result to discuss treatment with your GP.
Menopause before 40 is called premature ovarian insufficiency (POI). It matters because it affects long-term bone and heart health, and treatment is usually recommended until the average age of menopause. If you’re under 40 and your periods have become irregular or stopped, alongside menopausal symptoms, see your GP. A private blood test can give you results to take to that appointment, but it shouldn’t replace it.
Routine hormone monitoring isn’t usually needed while you’re on HRT. Your prescriber may ask for oestradiol to be checked in some situations, such as when symptoms continue despite treatment. For that, the separate menopause HRT panel is the relevant test. Always follow your prescriber’s advice on timing.
Swift takes venous blood samples at clinics across Essex, plus Bromley and Sunbury, and on home visits across Essex, Bromley and Surrey. Use the clinic finder to choose a location. Our guide to whether blood tests can detect perimenopause covers what testing can and can’t show in more detail.
A few simple steps make your result more useful:
Taking these notes to your GP alongside your result helps them see the full picture.
Not usually if you’re over 45 with typical symptoms. NICE recommends diagnosis based on symptoms.
Usually FSH, sometimes with oestradiol. Its main use is for women under 45.
Yes. Between 40 and 45, an FSH test may help when you have symptoms and changes to your periods.
Not reliably, because hormone levels fluctuate. A normal result doesn’t rule it out.
Yes, both affect FSH. Never stop prescribed treatment to take a test.
See your GP. Premature ovarian insufficiency needs medical assessment.
If you’re under 45 or your symptoms are unclear, book Swift’s menopause blood test at a clinic or at home.
