Hormone Blood Test UK: What’s Included For Men & Women

Many of us experience symptoms that are difficult to pin down. Persistent fatigue, unexpected weight changes, mood swings, or a sudden change in libido affect millions of people across the UK. these unexplained issues can be signs of an underlying hormonal imbalance in some cases

Historically, hormone testing was mainly reserved for specialist concerns, such as investigating fertility issues. Today, checking your hormone levels is becoming a key part of proactive health management for both men and women. Testing is more accessible than ever, allowing you to build a clearer picture of your internal health. This article is for general information and does not replace advice from a qualified clinician.

This guide provides a clear, comprehensive overview of hormone blood tests in the UK for both men and women. Whether you are experiencing worrying symptoms or simply want to understand your hormonal health, you will learn the signs of a hormonal imbalance and exactly which hormones are measured. We also explain your options for arranging a test in the UK, from the NHS to at-home kits, and what steps you should take once you receive your results.

What is a hormone blood test?

A hormone blood test is a diagnostic tool that measures the amount of specific chemical messengers in your blood to investigate symptoms and monitor existing health conditionsBy checking levels produced by your endocrine system, these tests help doctors identify imbalances affecting metabolism, mood, and reproductive health.

What are hormones and why do they matter?

Hormones are chemical messengers that regulate most of your body’s major processes. They travel through your bloodstream to tissues and organs, controlling everything from metabolism and mood to sleep cycles and sexual function.

These chemicals are produced by your endocrine system, which includes several key glands. The pituitary gland in your brain acts as a master control centre, while your thyroid gland regulates energy. Your adrenal glands manage stress responses, and your reproductive organs (the testes in men and ovaries in women) produce hormones essential for sexual health and fertility. When these glands produce too much or too little of a specific hormone, it can have a significant impact on how you feel.

Why test your hormone levels?

Doctors order a hormone profile to understand what is happening inside your body. Hormone blood tests are commonly used to assess fertility, investigate menstrual problems, check thyroid function, and monitor certain health conditions.

In clinical practice, we use these tests to determine if a specific endocrine gland is functioning normally. Beyond diagnosing an illness, a comprehensive panel can help identify suboptimal levels of certain hormones, giving you and your doctor more information to help optimise your health.

Signs you need a hormone test

The most common symptoms indicating you might need a hormone test include a unexplained weight changes, extreme tiredness, mood instability, and disruptions to your sleep or sexual function. Usually these come as a combination when due to hormonal imbalance.

Common symptoms

Because hormones regulate so many bodily systems, an unbalanced endocrine system can present in many different ways. Symptoms that can affect anyone, regardless of sex, include:

• Unexplained weight gain or weight loss
• Persistent fatigue and low energy
• Mood swings, anxiety, or depression
• Sleep problems and insomnia
• Noticeable changes in skin, such as sudden adult acne or dryness
• Thinning hair or hair loss

Symptoms in women

Female hormones naturally fluctuate throughout the month, but significant imbalances can cause disruptive symptoms. Signs relevant to female reproductive hormones include irregular, missed, or unusually heavy periods. You might also experience hot flushes, night sweats, low libido, or excessive hair growth on the face and body (hirsutism).

These symptoms are often linked to conditions such as polycystic ovary syndrome (PCOS) or the transition into menopause. It is worth noting that for some symptoms, reproductive hormones are not always the first thing we check for example depending on symptoms thyroid tests may be done. If you have abnormal vaginal bleeding in some cases you may need urgent investigation e.g. are post menopausal. If you have symptoms and irregular bleeding - it is best to speak to a doctor. They may need to investigate this further and in some cases urgently.

Symptoms in men

In men, hormonal symptoms typically relate to testosterone deficiency or thyroid issues. Specific signs of a male hormonal imbalance include a reduced sex drive, erectile dysfunction, a noticeable loss of muscle mass, and the development of breast tissue (gynaecomastia).

Men may also experience irritability, a lack of motivation, and difficulty concentrating. NICE guidance outlines these specific signs as key indicators that a doctor should assess a patient for testosterone deficiency.

What does a hormone test panel include?

A comprehensive hormone blood test measures a specific panel of biomarkers, including sex hormones like oestrogen and testosterone, alongside metabolic markers like thyroid and adrenal hormones.

Hormones tested in women

A typical female hormone panel assesses hormones crucial for regulating the menstrual cycle, fertility, and overall wellbeing.

The hormones regulate your periods so change throughout your cycle. The high level and low levels, listed below need interpreting alongside your symptoms and may need to be repeated. Generally doctors will interpret the female hormones based on the pattern rather than one off tests.

Oestradiol (E2) Oestradiol is the primary form of oestrogen in women of childbearing age. It regulates the menstrual cycle, maintains reproductive tissues, and supports bone health. High levels can sometimes be linked to bloating, weight gain, and heavy periods. Suboptimal or low levels, often seen during menopause, can lead to hot flushes, night sweats, and vaginal dryness.

Progesterone Progesterone helps prepare the lining of the uterus for a fertilised egg and maintains early pregnancy. The NHS notes that a progesterone blood test is frequently used to check whether a woman is ovulating. High levels are normal during pregnancy but can otherwise cause fatigue and mood changes. Low levels can result in irregular periods and trouble conceiving.

Follicle-Stimulating Hormone (FSH) FSH is produced by the pituitary gland and stimulates the ovaries to produce eggs. High levels of FSH are typically a sign that the ovaries are responding less, which happens as women approach menopause which is normal or in cases of premature ovarian insufficiency. Low levels can indicate a problem with the pituitary gland and may cause irregular cycles or infertility. Routine hormone blood tests are not generally needed to diagnose perimenopause if you are over 45 with perimenopause symptoms.

Luteinising Hormone (LH) LH works alongside FSH to regulate the menstrual cycle. A surge in LH triggers ovulation (the release of an egg). High levels are often seen in women with PCOS or those entering menopause. Low levels can signal an issue with the pituitary gland, leading to absent periods.

Testosterone While often thought of as a male hormone, women produce small amounts of testosterone in the ovaries and adrenal glands. It supports bone density, muscle mass, and libido. High levels in women can cause acne, excessive body hair, and irregular periods, often pointing to PCOS. Low levels may contribute to a lack of energy and reduced sex drive.

Prolactin Prolactin stimulates breast milk production after childbirth. In women who are not pregnant or breastfeeding, high levels can disrupt the menstrual cycle, cause unexpected milk production, and lead to fertility issues. Low levels are rare and usually do not cause significant problems.

Hormones tested in men

A male hormone panel primarily focuses on testosterone and the related hormones that control its production and impact energy, libido, and muscle mass.

Total Testosterone Total testosterone measures all the testosterone in the blood, both attached to proteins and freely floating. It influences muscle mass, bone density, fat distribution, and sex drive. High levels are uncommon naturally but can result from taking steroid medications, causing mood swings and increased risk of heart problems. Low levels lead to fatigue, erectile dysfunction, loss of body hair, and reduced muscle strength.

Free Testosterone This is the tiny fraction (usually around two per cent) of testosterone that is not bound to proteins. It is the active form that your body's tissues can easily absorb and use.

Sex Hormone-Binding Globulin (SHBG) SHBG is a protein produced by the liver that binds to sex hormones, controlling how much free testosterone is available in the body. High SHBG levels mean less free testosterone is available, which can cause symptoms of low testosterone even if total levels appear normal. Low SHBG can indicate metabolic issues or obesity.

Luteinising Hormone (LH) In men, LH tells the testes to produce testosterone. High levels of LH alongside low testosterone suggest the testes are failing to respond to the brain's signals. Low levels of LH suggest the pituitary gland is not sending the signal to produce testosterone in the first place.

Oestradiol (E2) Men need small amounts of oestradiol for joint health, brain function, and sperm production. High levels in men can lead to weight gain, erectile dysfunction, and the development of breast tissue. Low levels can negatively impact bone density and libido.

Related biomarkers

A comprehensive test often includes hormones not specific to sex, as these also heavily influence how you feel.

Thyroid Panel A thyroid panel typically includes Thyroid Stimulating Hormone (TSH), Free T4 (FT4), and sometimes Free T3 (FT3). These tests are used to diagnose and monitor an underactive or overactive thyroid. These hormones help regulate your metabolism. If they are unbalanced, you may experience extreme fatigue, unexplained weight changes, and temperature sensitivity. NICE guidance details exactly how these biomarkers should be used to assess thyroid disease.

Adrenal Hormones Many panels include cortisol, often called the stress hormone. Repeated high levels suggest chronic stress or medical conditions like Cushing's syndrome, while low levels can indicate adrenal insufficiency. DHEA-S, a precursor hormone produced by the adrenal glands, is also frequently measured to evaluate adrenal function. It can fluctuate over the day and you will usually need to repeat this to check if raised.

Getting a hormone test in the UK

You can get a hormone blood test in the UK through an NHS GP consultation, by booking a test with a private clinic or online doctor service, or by ordering an at-home finger-prick test kit.

Your doctor will assess your symptoms and may order an NHS blood test if they suspect a specific clinical condition. Alternatively, many people choose private clinics or tech-enabled platforms to proactively screen their health and access a broader range of biomarkers. Finally, you can easily order at-home testing kits online; modern UK tests are strictly regulated by bodies like the MHRA to ensure safety, as outlined in GOV.UK guidance.

Each private clinic may offer its own package so check what is included.

Preparing for your hormone test

To get accurate results from a hormone blood test, you may need to time your test to a specific point in your menstrual cycle, take the test early in the morning, or pause certain medications, depending on your doctor's advice.

Best time to test

Hormone levels fluctuate naturally, so timing your blood sample correctly is important.

• For menstruating women: Your doctor will usually ask you to take the test on a specific day of your cycle. Around day three of your cycle is common for testing baseline fertility markers like FSH and LH. Day 21 (or seven days before your expected period) is typical for measuring progesterone to confirm ovulation. If your cycles are irregular, your clinician will help you determine the best time to test.
• For men: Testosterone levels naturally peak early in the day. NICE guidance recommends that men having their serum testosterone measured should provide a blood sample in the morning, ideally between 8 am and 11 am.
• For post-menopausal women: Because hormone levels remain relatively steady after menopause, you can typically take the test at any time of the month.

Fasting requirements

Fasting is not usually required for a standard hormone-only panel. Always follow the specific instructions provided by your clinic or laboratory. You will generally be told when this you need to fast but it is best to check

Medication effects on results

Medications designed to alter your hormones, such as the contraceptive pill, hormone replacement therapy (HRT), or testosterone gels, can impact your blood test results. Taking these medications does not mean you cannot have a test, but it changes how the doctor will interpret the report. Always inform your doctor about all medications you are taking, and follow their advice on whether to pause any medication before your test.

Understanding hormone test results

Your hormone test results mean little in isolation; they must be interpreted alongside your personal health history and symptoms, and any abnormal results should be discussed with a qualified doctor to determine your next steps.

Reference ranges

When your blood is processed at the laboratory, your specific hormone levels are measured against a "reference range". This range represents the levels typically found in a healthy population and can vary significantly based on your age, sex, and the specific laboratory equipment used to analyse the sample.

It is important to remember that falling inside the "normal" range does not always mean your levels are "optimal" for you as an individual. Some people experience symptoms even when their hormones are technically within normal limits so results are interpreted alongside your symptoms

Abnormal results

Receiving an abnormal result can feel worrying, but the first step is always to discuss the report with a qualified healthcare professional. An abnormal or borderline result is rarely a final diagnosis on its own. It is a starting point for a conversation. Hormones fluctuate, and a doctor may want to repeat the test a few weeks later to confirm the finding, or order additional investigations to build a clearer clinical picture.

Next steps

A doctor interprets your blood test results in the context of your lifestyle, medical history, and how you actually feel day-to-day. Based on this review, your GP might suggest lifestyle changes, prescribe medication, or monitor your levels over time.

If your results show a complex endocrine issue, your GP can refer you to a specialist endocrinologist or a gynaecologist for expert care. If you have test results you want to understand better, our clinicians can help. You can book an appointment with a Doctor Care Anywhere GP for a thorough review and professional guidance.
