Perimenopause and menopause test: How to know where you stand

Something feels off. Your periods are unpredictable, you're waking up drenched at 3am, and your mood has become a rollercoaster. You're wondering: is this perimenopause, or something else?

A perimenopause test measures key hormones to help determine if your symptoms are hormonally driven and where you are in the transition. Understanding your hormonal status helps you make informed decisions about symptom management, Hormone Replacement Therapy (HRT), and supporting your long-term health.

At Everlab, we test a full hormone panel, rather than just FSH, because perimenopause affects multiple systems at once. Let our comprehensive testing help provide a clearer picture of your health.

What is a perimenopause test?

A perimenopause test is a blood test that measures the hormones involved in the menopausal transition. Here's what we look at:

• FSH (Follicle-Stimulating Hormone): This rises as ovarian function declines. Consistently elevated FSH (above 25 IU/L) suggests perimenopause. Levels above 40 IU/L typically indicate menopause.
• Oestradiol (E2): Drops as the ovaries produce less oestrogen. Low levels help explain declining ovarian function and symptoms like night sweats, hot flushes, vaginal dryness, and mood changes.
• LH (Luteinising Hormone): Rises during menopause, though it's less diagnostic than FSH on its own.
• AMH (Anti-Mullerian Hormone): Reflects your remaining egg reserve. Very low or undetectable AMH points to late perimenopause or menopause.
• TSH (Thyroid-Stimulating Hormone): This is important to test alongside reproductive hormones, as an underactive thyroid can mimic perimenopause symptoms (fatigue, weight gain, brain fog).

Why should you get tested?

Women usually seek a perimenopause test when their symptoms become disruptive, but testing offers more than just validation.

• To investigate the cause of your symptoms: Is it perimenopause, a thyroid issue, or stress? Testing provides objective data to help differentiate these conditions.
• To guide treatment choices: If your oestrogen levels are low, HRT or other targeted interventions can provide significant support. Your doctor needs data to prescribe effectively.
• To assess fertility: If you're trying to conceive later in life, AMH and FSH levels are important for understanding your timeline and options.
• To protect your bones and heart: Oestrogen is highly protective. When it drops, your risk of osteoporosis and cardiovascular disease can increase. Knowing where you are in the transition allows you to intervene early.

The timing of your perimenopause test

Hormones fluctuate during perimenopause. A single test provides a snapshot, but it's most useful when timed correctly.

• If you are still having periods: We recommend testing on days 2 to 5 of your cycle to capture baseline FSH and oestradiol.
• If your periods have stopped: You can test at any time.

Because a single snapshot can be misleading during perimenopause, Everlab focuses on the trend over time. By repeating the panel in 3 to 6 months, we map the trajectory of your hormone levels, not just a single point in time.

Understanding your results

How to book your perimenopause test with Everlab

1. Book online or contact the Everlab team.
2. Complete a brief health and symptom questionnaire.
3. Attend a convenient local clinic for your blood draw (we will advise you on the optimal cycle day if you are still menstruating).
4. Receive doctor-reviewed results with a clear summary of where you are in the transition.
5. Optional: Book a follow-up consultation to discuss HRT, supplements, and lifestyle strategies.

Frequently asked questions

1. Can a blood test definitely tell me if I'm in perimenopause?

Blood tests measure hormone levels that indicate the transition, but perimenopause is also a clinical diagnosis based on your symptoms and history. Because hormones fluctuate, a single test may not be conclusive. Combining repeat testing with symptom tracking gives the clearest picture.

2. My GP says I don't need a test and I should just wait. Is that right?

Some GPs take a symptom-based approach, especially if you're in the typical age range. While that is a valid clinical path, testing adds another layer of information. It can help confirm the hormonal basis of your symptoms, rule out thyroid conditions, and provide data that supports a confident conversation about treatment.

3. Can I take this test while on HRT?

Yes. Testing while on HRT can be useful because it shows your current hormone levels on your existing dose. Your results will reflect both your natural production and the exogenous hormones, which helps your doctor with potential dose adjustments.

4. What if my results show premature menopause (before 40)?

Premature ovarian insufficiency (POI) affects about 1% of women. It has implications for bone density, cardiovascular health, and fertility. Early detection allows for proactive management.
