Medichecks Testosterone Test Review 2026

General information, not medical advice. This is an independent review, we’re not affiliated with Medichecks. Last updated September 2026.

Quick verdict

Medichecks’ testosterone test is the cheapest credible starting point in the UK at £19, with a fast, well-run process and a doctor’s comment included. The catch: it measures total testosterone only, the free finger-prick option isn’t the one Medichecks itself recommends, and a low result feeds into a TRT clinic the company owns.

At a glance

What you get, and what’s actually tested

The base £19 test measures total testosterone — a single figure combining both the testosterone your body can use freely and the portion bound to proteins and inactive. It doesn’t distinguish between the two, which matters if your total comes back “normal” but you still have symptoms, that’s a free-testosterone question, not a total-testosterone one. (We cover the difference in more detail in our testosterone testing guide.)

If your result is borderline, Medichecks’ own next step is to upsell you to their Free and Total Testosterone test, which adds SHBG and a calculated free testosterone reading. Worth factoring in before you buy: £19 may not be your final cost if you want a complete answer the first time.

Sample collection process

1. Order online; the kit arrives by post with step-by-step instructions
2. Take your sample between 6am and 10am — testosterone peaks in the morning, and testing later in the day can read artificially low
3. Skip biotin supplements for two days beforehand, as biotin can interfere with the lab assay
4. Post the sample back in the prepaid envelope
5. Results land in your online account in around 2 working days of the lab receiving it, with a doctor’s comment attached unless you opted out

Pricing breakdown

This is the section worth reading closely. Medichecks explicitly recommends venous collection over finger-prick for this test, to avoid sample contamination from testosterone gels, creams, or residue on skin and surfaces. That guidance is easy to miss on the product page. If you’re already using a topical treatment, the “free” finger-prick option isn’t the one the provider itself would choose for you, and the real price is closer to £54–£78.

Accuracy and reliability notes

Beyond the contamination risk above, two other factors affect reliability: timing (samples taken outside the 6am–10am window may not reflect your true baseline) and biotin interference (common in multivitamins and hair/skin/nail supplements, worth checking your own supplement stack before testing). Medichecks flags both directly in their test instructions, which is a reasonable sign of transparency.

Reference ranges and what results mean

Medichecks uses a men’s reference range of roughly 8.7–29 nmol/L, based on British Society for Sexual Medicine (BSSM) 2022 guidance, which set 12 nmol/L as the threshold below which TRT eligibility discussions typically start. A result between 8 and 12 nmol/L without symptoms is treated by Medichecks as satisfactory rather than automatically flagged — useful context before you test, since a lot of anxiety around this test comes from not knowing where the actual thresholds sit.

Company reputation and conflicts of interest

Medichecks has operated since 2001 and holds a strong Feefo score (4.7/5 across 14,000+ five-star reviews). One thing every reader should know before testing here: Medichecks owns Leger Clinic, a TRT provider. If your result comes back low, don’t be surprised if the recommended next step leads toward that clinic rather than a neutral GP referral — it’s not necessarily bad advice, but it isn’t independent advice either.

Who it’s a good fit for

• You want the cheapest reliable first check and aren’t currently using any topical testosterone product
• You’re comfortable with a total-testosterone-only result as a starting point, not a final answer
• You want a fast turnaround without booking a GP appointment

Who it’s less suited to

• Anyone currently on TRT or using testosterone gel/cream (venous draw is strongly advised here, adding £35–£59)
• Anyone who wants free testosterone and SHBG from the outset, to avoid paying for two tests
• Anyone who specifically wants a treatment pathway independent of the test provider

How it compares

Against ZAVA, Medichecks is cheaper for a first check but ZAVA’s kits sit within a pharmacy-registered service rather than a lab-only model. Against Randox Health’s Tasso+ device, Medichecks’ finger-prick method is more convenient but, per Medichecks’ own guidance, less reliable if you’re using topical testosterone. See our full comparison of UK testosterone test kits for the complete picture.

Bottom line

At £19, this is hard to beat as a first check, and the process itself is fast and well-documented. Just budget for a higher real cost if you need venous collection, and go in aware that a low result leads toward Medichecks’ own TRT clinic rather than a fully independent pathway.

FAQ

Does the £19 price include a doctor’s comment? 

Yes, it’s included by default, you can opt out if you already have a clinician who will interpret the result for you.

Can I use this test while on TRT? 

Yes, Medichecks markets it as suitable for monitoring while on treatment, though they also offer a dedicated TRT-specific test that additionally checks liver health.

Why does Medichecks recommend a venous sample over finger-prick for this test specifically? 

Because finger-prick samples are more vulnerable to contamination from testosterone gels, creams, or contact with contaminated surfaces, a risk that doesn’t apply to a venous draw.

Is the £19 test enough on its own? 

For a first, low-cost check, yes. If the result is borderline or your symptoms don’t match a “normal” total testosterone reading, a free testosterone/SHBG panel will likely be the more useful next step.
