Best Home Testosterone Blood Tests in the UK (2026)

Home testosterone tests are a quick way to get a number, but the number only means something if the sample is taken correctly and read in context. Here is what to buy, and how to avoid a misleading result.

Our picks at a glance

How we chose

We looked at UK providers selling testosterone tests direct to the public and checked each product page for price, the exact markers included, sample options and timing advice. We favoured tests that include SHBG and free testosterone, because total testosterone alone can mislead. We noted where a provider also sells testosterone treatment, since that is a commercial interest. Evidence grades reflect that these are standard lab measurements; the grade is Moderate rather than Strong because finger-prick samples add some error and we have not seen independent head-to-head accuracy data for each provider.

What should a home testosterone test measure?

• Total testosterone: all the testosterone in your blood. This is the first number a GP looks at.
• SHBG (sex hormone binding globulin): a protein that carries testosterone around and holds onto it. If SHBG is high, less testosterone is available to your body even when the total looks fine. If it is low, the opposite.
• Free testosterone: the small fraction not bound to proteins. Home tests usually calculate this from total testosterone, SHBG and albumin rather than measuring it directly.
• LH and FSH: messages from the brain telling the testes to work. They help a doctor tell whether a low level starts in the testes or in the brain.
• Prolactin and oestradiol: other hormones that can affect libido and testosterone.

Why does the time of day matter?

Testosterone peaks in the morning and falls through the day, by a meaningful amount in younger men. That is why the British Society for Sexual Medicine recommends a morning sample, repeated to confirm, before anyone diagnoses deficiency. The providers here say the same: Medichecks asks for samples between 6am and 10am, Forth between 8am and 10am, and London Medical Laboratory between 7am and 10am. Avoid hard exercise and sex for 48 hours beforehand, and stop biotin supplements for two days, as they can interfere with some lab tests.

Finger-prick or venous?

Finger-prick kits are cheaper and easy, but they are more prone to problems: not enough blood, clotted samples and, for testosterone, contamination. Medichecks strongly recommends a venous (arm vein) sample if anyone in your household uses testosterone gel, as traces on your fingers can push results up. Venous options cost £35 to £59 extra. Arm devices like Forth's AutoDraw and Numan's Tasso+ sit in between.

Our picks

Medichecks Male Hormone Blood Test (Best overall)

At £79, it covers total and calculated free testosterone, SHBG, albumin, LH, FSH, oestradiol, prolactin and DHEA-S. That is the set a specialist would want to see, and an optional PSA add-on is available. Caveat: for the most reliable result, pay for a venous sample, and remember one test is not a diagnosis.

Medichecks Testosterone Blood Test (Budget pick)

At £19, this is the cheapest way to get a total testosterone number from a large UK provider. It is a sensible first check if you simply want to know whether you are in range. Caveat: without SHBG, a borderline result is hard to interpret.

Forth Testosterone Home Blood Test Kit (Alternative)

Forth's £29 kit measures total testosterone, with an AutoDraw arm device for £20 extra if you struggle with finger-pricks. Caveat: single marker only.

Numan Testosterone Blood Test (Also consider)

Numan's test (from £68) includes total and free testosterone, SHBG and albumin, collected with a Tasso+ device on the upper arm. Caveat: Numan also sells testosterone treatment, so take any low result to your GP for an independent view.

Forth Male Hormone Home Blood Test Kit (Alternative)

£89 for 12 markers, adding a thyroid panel (TSH, free T4, free T3) and morning cortisol. Useful because tiredness is often blamed on testosterone when the thyroid is the issue. Caveat: more markers raises the chance of a borderline result that causes worry.

London Medical Laboratory Male Hormone Profile (Premium pick)

A £99 10-marker panel similar to Medichecks, with finger-prick or in-person phlebotomy. Caveat: dearer than near-identical panels elsewhere.

Randox Health Everyman and Everywoman (Also consider)

A £416 clinic check with up to 150 data points, including a hormone section. Caveat: expensive, and Randox does not list every marker by name, so check testosterone and SHBG are included before booking.

Which test should you choose?

How do I get an accurate home result?

• Sample on waking, between about 7am and 10am, ideally before breakfast.
• Drink water the evening before and warm your hands (a warm shower helps blood flow for finger-pricks).
• Wash hands thoroughly; if anyone at home uses testosterone gel, wear gloves or choose a venous draw.
• Post the sample the same day, Monday to Thursday, so it does not sit in the post over a weekend.
• Note any medicines and supplements (especially biotin) on the form.
• Repeat any low result on a different morning.

What to avoid

• Saliva testosterone tests. UK guidance is based on blood tests; saliva results are harder to compare with standard ranges.
• Afternoon samples. They can make normal levels look low.
• Acting on one result. Repeat any low or borderline result in the morning before drawing conclusions.
• Tests sold as a funnel into treatment without an independent GP opinion.

What should I do with my results?

Home tests are not diagnostic. If your result is low, borderline or unexpected, book a GP appointment and bring the report. Your GP can repeat the test on the NHS, look for other causes such as thyroid problems, sleep apnoea, medicines, weight or depression, and refer you if needed. The NHS stresses that many midlife symptoms are not hormonal at all.

Bottom line

For most men, a mid-priced panel with SHBG and free testosterone, taken in the morning (ideally from a vein), is worth more than a cheap total-only test. If budget is tight, the £19 Medichecks test is a reasonable first look. Whatever you buy, treat the result as a starting point for a GP conversation, not a diagnosis.
