A Perimenopause Blood Test involves measuring specific hormone levels in your blood to assess whether you might be in the transitional phase leading up to menopause, known as perimenopause.

Key hormones typically assessed include follicle-stimulating hormone (FSH) and oestradiol, among others. These hormone levels can fluctuate during perimenopause, providing insights into changes that may be occurring in your body.

Assessing hormonal changes associated with perimenopause can be conveniently done at home using our finger-prick blood test kit. Once you collect the sample, it is sent to our laboratory for analysis. The results will provide insights into your current hormone levels. Do note that this blood test does not diagnose perimenopause, but instead may help explain some of your symptoms.

The Perimenopause Blood Test checks 12 biomarkers including Oestradiol and Progesterone, which are hormones that play a central role in perimenopause. We also include AMH (Anti-Müllerian hormone), which can provide insights into reproductive health and egg reserve, particularly in evaluating how close someone may be to menopause. Beyond these three, this test also checks FSH, LH, Total Testosterone, SHBG, Free T4, TSH, FAI, Vitamin D and Prolactin.

If you’re starting to notice changes like irregular periods, mood swings, or hot flushes — especially if you’re over 45 — the Perimenopause Blood Test can help you understand what’s happening beneath the surface. It looks at key hormones such as oestradiol and FSH to spot the fluctuations common in early perimenopause, AMH to help gauge how close you might be to menopause, and progesterone and LH to check whether ovulation is becoming irregular. You’ll also get insight into other important markers like thyroid function (Free T4 and TSH), testosterone, and Vitamin D, so you can see the bigger picture of your health during this stage.

If your periods have stopped for 12 months and you’re experiencing menopause symptoms, the Menopause Blood Test offers a clear confirmation and a fuller understanding of your hormone health. It measures oestradiol and FSH (where high FSH and low oestradiol can indicate menopause), alongside progesterone and LH to confirm reduced ovarian function. Additional markers like testosterone, SHBG, Free T4, and TSH give a complete overview, helping you and your healthcare team make more informed decisions about symptom management and long-term wellbeing.

This test checks key fertility hormones like AMH, FSH, LH, and oestradiol, which can help you and your doctor understand your ovarian reserve and ovulation patterns. However this test alone can not diagnose fertility problems. 

This test provides clinically valid results that can help identify typical hormone fluctuations during perimenopause. However, it's important to remember that hormone levels can vary widely within and between cycles, so the test provides a snapshot of your hormone profile rather than a comprehensive diagnosis.

The findings from a perimenopause test can help to reveal if your hormone levels are undergoing changes consistent with the perimenopausal transition. This information can help explain symptoms you may be experiencing, such as hot flushes, mood swings, or changes in menstrual cycle regularity.

For the most accurate results, take the test on Day 2 to Day 5 of your menstrual cycle, ideally on Day 3. Day 1 is the first day of bleeding.

If you have irregular periods, we recommend that you wait until your next cycle to test as close to Day 3 as possible.

If you have no periods, for instance, due to a type of contraception you may be using, you can take this test on any day, but it might be harder for our doctors to interpret your results. If you haven't had a period in over 12 months, check out our Menopause Blood Test.

Fasting is not required for this blood test.

With the finger prick test, you may feel a small prick and the area may be a bit tender afterwards. With the Tasso+ device, you can easily collect blood without pricking your finger. Attach the device to your upper arm and press—it's as simple as that.

Some biomarkers such as AMH and thyroid hormones can be tested while on hormonal contraception, but results for FSH, LH, or oestradiol - which are included in this test - will not show your natural cycle due to hormonal contraception. 

If you’re stopping the pill, wait until your periods return to normal before testing. We recommend using alternative contraception if you’re not planning pregnancy.
