Blood test home kit UK
Male Hormone and Fertility Blood Test Home Kit UK
An eight marker panel linking total and free testosterone with pituitary signals, binding proteins, prolactin and thyroid context.
One low testosterone result does not show whether the origin is testicular, pituitary, thyroid related, medicine related or temporary. This panel is structured around the hormone pathway rather than one headline number.
When it may be considered
Start with symptoms, risk and the reason for testing
- Reduced libido or fewer morning erections
- Erectile dysfunction
- Persistent tiredness with reduced strength
- Fertility concerns alongside semen analysis
- An earlier low or borderline testosterone result
- Confirming fertility without semen analysis
- Diagnosing testosterone deficiency from one sample
- Starting testosterone when future fertility matters without specialist discussion

Eight marker detail
Result bands and clinical context
Luteinising hormone
Luteinising hormone, known as LH, is released by the pituitary gland. In men it stimulates Leydig cells in the testes to produce testosterone.
A lower result can occur with pituitary or hypothalamic suppression, acute illness, obesity, opioid use, anabolic steroids, testosterone treatment or other medicines.
Interpret it with testosterone, FSH, prolactin and symptoms.The result falls within the laboratory interval.
A normal LH does not exclude a pituitary cause if testosterone is low because the value may be inappropriately normal.A raised result can indicate that the pituitary is increasing stimulation because the testes are not responding adequately.
Discuss the result with a GP or endocrinology professional.Albumin
Albumin is the main protein in blood plasma and carries hormones, medicines and other substances. Some testosterone binds loosely to albumin.
A very low result can occur with serious liver disease, kidney protein loss, severe inflammation, malnutrition or critical illness.
Arrange prompt clinical review and follow urgent laboratory advice.A lower result can reflect inflammation, liver disease, kidney loss, poor intake, malabsorption or fluid overload.
Discuss it with a GP and consider wider liver, kidney and inflammatory testing.The value sits inside the reporting laboratory’s stated interval.
Use it as part of free testosterone interpretation where relevant.A high result most commonly reflects dehydration or concentration of the blood sample.
Review hydration and discuss a persistent unexpected result with a clinician.Free testosterone
Free testosterone represents the small fraction of testosterone that is not tightly bound to SHBG or albumin and is available to tissues.
A lower result can support reduced androgen availability when compatible symptoms are present. Causes can include testicular, pituitary, hypothalamic, medicine, metabolic or systemic illness factors.
Confirm the finding with clinical assessment and appropriate repeat testing.The result falls within the laboratory interval.
Persistent symptoms may still require evaluation for sleep, mood, thyroid, medication, vascular or other causes.A raised result can reflect testosterone treatment, anabolic steroid use, low SHBG, assay factors or less common endocrine conditions.
Discuss an unexpected result with a clinician.Thyroid stimulating hormone
Thyroid stimulating hormone, known as TSH, is produced by the pituitary gland and regulates thyroid hormone production.
A markedly suppressed TSH may occur with significant thyroid overactivity, excessive thyroid medicine or other medical factors.
Arrange prompt review, especially with palpitations, weight loss, heat intolerance or tremor.A lower result can occur with an overactive thyroid, thyroid medicine, recent illness or pituitary factors.
A free T4 and sometimes free T3 result may be required.The result falls within the laboratory range.
A normal TSH makes common primary thyroid dysfunction less likely but does not exclude every thyroid or pituitary condition.A high result most commonly occurs when the thyroid is underactive or replacement treatment is insufficient.
Discuss the result with a GP and arrange free T4 testing.A very high result may indicate marked primary thyroid underactivity. Pituitary causes are much less common.
Arrange prompt clinical assessment.Sex hormone binding globulin
Sex hormone binding globulin, known as SHBG, is produced mainly by the liver and binds testosterone in the circulation.
A lower SHBG value can be seen with obesity, insulin resistance, an underactive thyroid, androgen exposure, liver factors or some medicines.
Interpret total testosterone with free testosterone and the wider metabolic context.The result falls within the laboratory interval.
Use it with total testosterone and albumin where free testosterone is calculated.A raised SHBG value can be seen with ageing, an overactive thyroid, liver disease, oestrogen exposure, some medicines or low body weight.
Discuss the complete hormone pattern with a clinician.Prolactin
Prolactin is produced by the pituitary gland. When persistently raised in men it can suppress LH and FSH, reduce testosterone and contribute to reduced libido, erectile dysfunction, breast changes or fertility problems.
A A lower result is often not clinically significant but value can be seen with dopamine agonist treatment or reduced pituitary function.
Discuss it with a clinician if other pituitary hormones are abnormal.The result falls within the laboratory interval.
A normal result makes clinically significant hyperprolactinaemia less likely.A raised result may be temporary or related to medicines, stress, hypothyroidism, kidney disease or pituitary disease.
Mild elevations are often repeated after resting and reviewing medicines.A markedly raised result requires prompt medical assessment, particularly with headache, visual change, breast discharge or low testosterone.
Seek urgent review according to the laboratory instruction.Total testosterone
Total testosterone measures testosterone circulating in both protein bound and unbound forms. It is the usual first laboratory test when testosterone deficiency is suspected.
A lower result can occur with primary testicular dysfunction, pituitary or hypothalamic suppression, obesity, acute illness, sleep disruption, medicines, anabolic steroid withdrawal or systemic disease.
Repeat on a separate morning and interpret with LH, FSH, SHBG, free testosterone and prolactin.The value sits inside the reporting laboratory’s stated interval.
Persistent symptoms may have another cause and still merit clinical assessment.A high result most often reflects prescribed testosterone, anabolic steroids, supplements containing hormones or assay factors. Less common endocrine causes are possible.
Discuss an unexpected result and all hormone products with a clinician.Follicle stimulating hormone
Follicle stimulating hormone, known as FSH, is released by the pituitary gland. In men it acts on Sertoli cells and supports sperm production.
A lower result can occur with pituitary or hypothalamic suppression, testosterone or anabolic steroid use, acute illness or some medicines.
Interpret it with LH, testosterone, prolactin and fertility history.The result falls within the laboratory interval.
A normal FSH does not prove that semen quality is normal.A raised result can suggest reduced sperm producing function or broader testicular dysfunction, particularly when semen analysis is abnormal.
Discuss fertility concerns with a GP, urologist or fertility specialist.Preparation protects the value of the result
Before collecting the sample
- Collect in the morning
- Record testosterone, anabolic agents and supplements
- Rest before collection because prolactin can be stress sensitive
- Avoid testing during acute illness where practical
Collection requirements can vary with the laboratory method, sample stability and clinical purpose. An insufficient, contaminated, delayed or incorrectly labelled sample may not be suitable for analysis.

Common questions
Clear answers without oversized FAQ cards
What is the best time for a testosterone blood test?
Morning collection is recommended because testosterone follows a daily rhythm.
Can one blood test diagnose low testosterone?
No. A low or borderline result usually requires repeat morning testing and clinical assessment.
What do LH and FSH show in men?
They are pituitary signals involved in testosterone production and sperm development.
Why is TSH included?
Thyroid dysfunction can overlap with fatigue, sexual symptoms and wider hormone concerns.
Does this panel assess fertility?
It provides hormone context but does not measure sperm count, movement or shape.
