Do you need a blood test for menopause?
FSH tests and home kits, explained.
LAST REVIEWED: 2026-10-29 • By the LatelyWell editorial team • How we write & review
Many women expect a hormone test to "prove" they are in perimenopause, and some are told they cannot have help without one. In fact, for most people over 45 the diagnosis is based on symptoms and periods, not blood tests. Here is what guidance from NICE, the FDA and the RCOG says.
The short answer
If you are 45 or over, otherwise healthy, and have menopause symptoms, you usually do not need a blood test. The NICE menopause guideline, which NHS clinicians in England follow, says perimenopause and menopause should be identified without laboratory tests in this group:
- Perimenopause: if you have hot flushes or night sweats that have recently started and any change in your menstrual cycle.
- Menopause: if you have not had a period for at least 12 months and are not using hormonal contraception.
- After a hysterectomy: based on the type and combination of symptoms you have, such as hot flushes.
Menopause usually happens between 45 and 55, according to the NHS, and Mayo Clinic gives the average age in the US as 51.
Why hormone levels are not a reliable test
During the menopause transition, hormone levels go up and down. The Royal College of Obstetricians and Gynaecologists (RCOG) explains that follicle-stimulating hormone (FSH) levels fluctuate through the menstrual cycle and during the menopause transition. A single result can look "normal" one week and raised the next.
For this reason, NICE says the following tests should not be used to identify perimenopause or menopause in people aged 45 or over: anti-Müllerian hormone (AMH), inhibin A, inhibin B, oestradiol, antral follicle count and ovarian volume.
When a blood test may be used
| Your situation | What NICE says |
|---|---|
| 45 or over with menopause symptoms | Diagnose from symptoms and periods, without lab tests |
| 40 to 45 with symptoms, including a change in your cycle | An FSH blood test may be considered to confirm menopause |
| Under 40 with suspected menopause | FSH may be considered. Premature ovarian insufficiency (POI) is diagnosed from symptoms plus raised FSH on 2 blood samples taken 4 to 6 weeks apart, never a single test |
| Using combined hormonal contraception or high-dose progestogen | Do not use an FSH test to identify menopause |
NICE also notes that menopause can be harder to identify in people taking hormonal treatments (for example for heavy periods), and that people from some ethnic minority backgrounds and people with some lifelong conditions may go through menopause at a younger age. Menopause between 40 and 44 is called early menopause, and NICE says psychological support should be offered to people who are distressed by an early menopause diagnosis.
A doctor may still suggest other tests if your symptoms are unusual or another cause seems possible. That is a decision for them to make with you.
What about home menopause test kits?
Home kits sold in pharmacies and online usually measure FSH in urine. The US Food and Drug Administration (FDA) says these tests detect FSH accurately about 9 out of 10 times, but that the test does not detect menopause or perimenopause. It only shows whether your FSH is raised at that moment.
- A positive result means you may be in a stage of menopause, and the FDA advises seeing your doctor.
- A negative result does not mean you are not in perimenopause or menopause. If you have symptoms, see your doctor anyway.
- Results can be affected by whether you used first-morning urine, drank a lot of water, or use (or recently stopped) the pill, contraceptive patch, HRT or oestrogen supplements.
- The FDA warns not to stop contraception based on these tests, because you can still become pregnant during perimenopause.
The RCOG does not recommend over-the-counter menopause tests, saying they are not a good method of detecting menopause or perimenopause because they only measure FSH rather than the wider clinical picture, and that they are of no value if you use hormonal contraception.
What to bring to your appointment instead
Because the diagnosis is mainly based on your symptoms and cycle, the most useful thing you can bring is a clear record. Note:
- the dates of your last few periods and any change in pattern, flow or length
- hot flushes and night sweats: how often and how bad
- sleep, mood, memory, joint aches, vaginal or bladder symptoms
- any contraception or hormone treatment you use
- what you would like help with, and any questions about treatment

Frequently asked questions
Can a blood test tell if I am in perimenopause?
Not reliably. Hormone levels such as FSH go up and down during the menopause transition. NICE says that for people aged 45 or over with symptoms, perimenopause and menopause should be identified without lab tests.
Do I need an FSH test to get HRT?
For most people aged 45 or over, NICE says menopause is identified from symptoms and periods, not blood tests. An FSH test may be considered for people aged 40 to 45 with symptoms and cycle changes, and for people under 40 when menopause is suspected.
Are home menopause tests accurate?
The FDA says home kits detect raised FSH about 9 out of 10 times, but they do not detect menopause or perimenopause, and a negative result does not rule it out. The RCOG does not recommend them.
Can I stop contraception if a home menopause test is positive?
No. The FDA warns not to stop contraception based on these tests, because you can still become pregnant during perimenopause. Ask a doctor or nurse when it is safe to stop.
How is early menopause or POI diagnosed?
NICE says premature ovarian insufficiency in people under 40 is diagnosed from symptoms plus raised FSH on 2 blood samples taken 4 to 6 weeks apart, not on a single test. For people aged 40 to 45, an FSH test may be considered.
Where to find reliable information
If you want to read further, these organisations publish free, evidence-based information for the public:
- UK: the NHS menopause pages, the NICE menopause guideline and the Women's Health Concern factsheets from the British Menopause Society.
- US: The Menopause Society, ACOG and the National Institute on Aging.
- Australia: Jean Hailes for Women's Health and the Australasian Menopause Society.
Guidance differs a little between countries, and treatment names and availability vary, so check what applies where you live and talk to a clinician about your own situation.
The bottom line
For most women over 45, menopause and perimenopause are recognised from symptoms and changes in periods, not blood tests, and home test kits cannot confirm either. Blood tests have a role for younger women. The best preparation for an appointment is a simple record of your symptoms and periods.
