Best Perimenopause Hormone Tests in the UK
A guide to the best perimenopause hormone tests available in the UK, including what to test, when to test, and how to interpret your results.
Do You Actually Need a Hormone Test?
This is a question worth addressing honestly. In the UK, NICE guidelines state that perimenopause is a clinical diagnosis based on symptoms and age in women over 45. Blood tests are not routinely required to diagnose perimenopause and are not always reliable because hormone levels fluctuate considerably throughout the menstrual cycle and between days. A single FSH or oestrogen reading tells you what was happening at one moment in time, not a stable picture of your hormonal status. That said, testing has real value in specific situations. If you are under 45, a blood test can help confirm or rule out early menopause. If you have an IUD or have had a hysterectomy and are not sure whether you are in perimenopause, testing can provide useful context. And if you are monitoring changes over time or considering HRT, baseline bloods are useful to have.
What Tests Are Most Relevant
The most informative hormone tests for perimenopause include FSH (follicle-stimulating hormone), oestradiol, and progesterone. FSH rises as the ovaries produce less oestrogen, and a significantly elevated FSH can indicate you are entering perimenopause or menopause. Oestradiol gives a snapshot of current oestrogen levels, though as noted, this fluctuates considerably. Beyond the reproductive hormones, a complete picture should include thyroid function (TSH, T3, T4) because hypothyroidism shares many symptoms with perimenopause, including fatigue, brain fog, weight gain, and low mood. DHEA-S, testosterone, and cortisol are also worth testing if energy, libido, and stress regulation are significant concerns. Vitamin D, iron, ferritin, and B12 round out a comprehensive panel.
NHS Testing: What You Can Access
Through your GP, you can request many of these tests on the NHS, though access varies by practice. A standard blood panel for perimenopausal symptoms might include FSH, oestradiol, thyroid function, full blood count, and B12. Some GPs are proactive about ordering comprehensive panels; others may require more advocacy on your part. If your GP declines to test, asking to see a practice nurse or requesting a referral to a gynaecologist or menopause clinic are both reasonable options. NHS menopause clinics, though not widely available in all areas, can offer more thorough testing as part of a full clinical assessment. If you cannot access what you need through the NHS, private testing is a practical alternative.
Home Testing Kits in the UK
Several companies now offer home hormone testing kits for perimenopause that you can order online. Medichecks is one of the most reputable and offers a Menopause Blood Test and an Advanced Menopause Blood Test that covers FSH, oestradiol, testosterone, SHBG, thyroid, and more. Results are typically available within a few days and come with a GP-reviewed report. Lets Get Checked offers similar services and ships to most UK postcodes. Thriva provides a subscription model where you can test regularly over time and track changes. These services typically range from 35 to 150 pounds depending on the breadth of the panel. Home testing involves a finger-prick blood sample rather than a full venous draw, which is accurate for most markers though some complex panels require a clinic visit.
Private Clinic Testing Options
For a more comprehensive assessment, private clinics offer full panels with blood draws and practitioner consultations to interpret results. The Newson Health Menopause Centre, Marion Gluck Clinic, and BUPA's women's health clinics all provide perimenopause-focused assessments. Nuffield Health offers private GP appointments that include blood testing. At the higher end, specialist functional medicine clinics offer dried urine testing (DUTCH test) which measures not just hormone levels but how the body metabolises hormones, providing a much richer picture of what is happening. The DUTCH test costs between 250 and 400 pounds typically. It is most useful for women with complex symptom pictures or those who have not responded as expected to standard HRT.
Interpreting Your Results
Results mean much more with context. A single elevated FSH does not confirm perimenopause on its own. What you are looking for is the combination of results alongside your symptoms. Many women find that their results come back within the normal reference range yet still have significant perimenopause symptoms. This is because reference ranges are based on population averages and do not reflect what is optimal for an individual. Working with a GP or practitioner who understands perimenopause, rather than simply comparing your results to a reference range, makes interpretation far more useful. If your GP dismisses clear symptoms because bloods are within range, seeking a second opinion from a menopause specialist is entirely reasonable.
Testing Timing Matters
If you are still having periods, the timing of testing in your cycle significantly affects results. Oestradiol and progesterone are best tested at specific cycle phases, typically day two or three for oestradiol and day 21 for progesterone. FSH is most meaningful when tested in the early follicular phase, around days two to five of your cycle. Testing at the wrong point can produce misleading results. If your periods are already very irregular, this is harder to time precisely. For home tests, the kit instructions will guide you on timing. For GP or clinic tests, ask your practitioner when to come in relative to your cycle. Recording the date of your last period and cycle length in advance helps ensure the test is done at the most informative time.
