Menopause Hormone Blood Test
Are symptoms like fatigue, brain fog, or hot flushes affecting your daily life? Distinguishing between perimenopause and thyroid issues can be difficult. This profile measures key female hormones (FSH, LH, Oestradiol) alongside thyroid function to clarify what's happening inside your body so you can take the right next steps.

What’s measured in this test
Each biomarker helps reveal insights into your health.
Follicle Stimulating Hormone
What is follicle stimulating hormone (FSH)
FSH is made by the pituitary gland in the brain. It stimulates the ovaries to grow follicles, which contain eggs, and helps regulate the menstrual cycle.
What a high result might mean
High FSH can mean the ovaries are not responding well, which happens naturally after menopause or earlier in conditions such as premature ovarian insufficiency. It can also rise after some medical treatments affecting the ovaries.
What a low result might mean
Low FSH can occur if the brain is not sending enough signals to the ovaries, often due to stress, significant weight loss, or excessive exercise. Hormonal contraception also lowers FSH levels while in use.
Free Thyroxine (FT4)
What is Free Thyroxine (FT4)?
Free Thyroxine (FT4) is one of the main hormones produced by your thyroid gland. FT4 is the active hormone that is available to travel throughout your body, regulating your metabolism, energy levels, and body temperature.
What does a High Result mean?
A high FT4 level usually means your thyroid gland is overactive (hyperthyroidism). This is most often caused by Graves' disease or thyroid nodules. A temporary rise can occur due to thyroiditis. Some supplements, particularly biotin, can interfere with the lab test.
What does a Low Result mean?
A low FT4 level usually means your thyroid gland is underactive (hypothyroidism). If your FT4 is low and your TSH is raised, this strongly points to a problem with the thyroid gland itself.
Luteinising Hormone
What is luteinising hormone (LH)
LH is made by the pituitary gland in the brain. It helps control the menstrual cycle and triggers ovulation — the release of an egg from the ovary.
What a high result might mean
High LH levels are normal around ovulation or after menopause. In younger women, they can suggest polycystic ovary syndrome or, if both LH and FSH are high, reduced ovarian function.
What a low result might mean
Low LH may mean the brain is not sending enough signals to the ovaries, often due to stress, weight loss, or excessive exercise. Some medicines and hormone treatments can also lower LH levels.
Oestradiol
What is oestradiol
Oestradiol is the main form of oestrogen in the body. It is made mainly by the ovaries before menopause and helps control the menstrual cycle, fertility, and bone and heart health.
What a high result might mean
Levels naturally rise around ovulation and in pregnancy. Some medicines or hormone treatments can increase it. Ovarian cysts or, rarely, hormone-producing growths can also raise oestradiol.
What a low result might mean
Low levels are normal after menopause. In younger women, they can happen if the ovaries are not releasing eggs, after major stress, weight loss, or excessive exercise. They can also fall if the pituitary gland is not sending the right signals to the ovaries.
Thyroid Stimulating Hormone
What is TSH?
TSH stands for Thyroid-Stimulating Hormone. It is a hormone produced by the pituitary gland (a master gland located in the brain). The pituitary gland acts like a thermostat, constantly measuring the amount of thyroid hormone in your blood.
The Signal: TSH is the signal the pituitary sends to the thyroid gland telling it how hard to work and how much hormone (FT4 and FT3) to produce.
The Best Test: Because of this feedback loop, TSH is the best initial test to check your overall thyroid function.
What does a High Result mean?
A higher TSH level usually means your pituitary gland is trying to push the thyroid to work harder.
Underactive Thyroid (Hypothyroidism): This is the most common reason. The thyroid gland is not producing enough hormone, so the pituitary increases the TSH signal to compensate.
What does a Low Result mean?
A low TSH level means your pituitary gland has slowed or shut down the signal because it senses there is too much thyroid hormone in your blood.
Overactive Thyroid (Hyperthyroidism): This is the most common reason.
Frequently asked questions
What is menopause?
Menopause is when your periods stop permanently because oestrogen levels fall. It’s diagnosed after 12 months without a period (not due to pregnancy, contraception, or illness). Most women reach it between 45 and 55.
What does the Menopause Profile measure?
This focused profile checks 5 key hormones:
FSH - follicle stimulating hormone (rises in menopause)
LH - luteinising hormone
Oestradiol - main female hormone (declines in menopause)
TSH - thyroid stimulating hormone
FT4 - free thyroxine
Who should take the Menopause Profile?
Women experiencing symptoms like hot flushes, night sweats, irregular periods, brain fog, or fatigue who want to clarify whether they're in perimenopause/menopause or if thyroid issues might be contributing.
What is perimenopause?
Perimenopause is the transition leading up to menopause. Hormone levels fluctuate and periods often change. Common symptoms include hot flushes, night sweats, mood or sleep changes, brain fog, and vaginal dryness.
Why check thyroid hormones in a menopause test?
Many menopause symptoms (fatigue, brain fog, mood changes) overlap with thyroid issues. Testing both helps distinguish between them and ensures you're not missing a thyroid problem that could be treated.
Can a blood test confirm menopause?
For ages 45–55, diagnosis is usually based on symptoms and period pattern; blood tests aren’t always needed. Testing can support assessment if you’re under 45, have had a hysterectomy or irregular cycles, or if there’s uncertainty.
Can this test diagnose menopause?
The test provides hormonal evidence supporting menopause diagnosis, but clinical diagnosis also considers your age, symptoms, and period pattern. It's a valuable piece of information for you and your doctor.
Who is this test for?
Women who want a clearer picture of hormone changes during perimenopause or menopause, including those considering treatment options or wishing to understand symptoms like hot flushes, low energy, sleep changes, or mood swings.
What can this test reveal?
It supports assessment of female hormone balance and thyroid function. Results may indicate patterns consistent with perimenopause or menopause and can help assess whether thyroid imbalance may be contributing to symptoms.
How should I prepare for the Menopause Profile?
Follow these steps:
No fasting required
Be well: Avoid testing during illness
Hydrate: Drink water
Bring ID: Photo ID and confirmation

How to Prepare?
• Take your sample when you’re well (avoid testing during short-term illness).
• Hydrate with water beforehand.
• Collect between 6–10am for the most stable hormone levels.
• Avoid biotin supplements for 48 hours unless prescribed.
• If you take thyroid medication: take natural desiccated thyroid or liothyronine after your sample; levothyroxine can be taken as usual.
• Bring photo ID and your order email to your appointment.
