Quick Verdict
ZAVA is an online pharmacy and doctor service rather than a pure diagnostics company, and its testosterone test reflects that positioning: a straightforward total-testosterone check from around £53, processed at a UK-accredited partner lab, with a doctor reviewing your result and advising on next steps. It’s a reasonable option if you’d rather your test and any resulting prescription conversation happen through the same regulated service, but you’re paying a premium over lab-only providers for that convenience, and the base test measures total testosterone only.

What You Get, and What’s Actually Tested
ZAVA’s home testosterone test measures total testosterone only — there’s no built-in option to add SHBG or free testosterone at the point of testing, which is a meaningful difference from panel-based providers like Randox or Medichecks’ higher-tier tests. What you are paying for, beyond the lab analysis itself, is a doctor’s review of the result and, if you’re already on prescribed treatment, a more direct route to a repeat prescription conversation, since ZAVA operates as a full online pharmacy and prescribing service rather than a lab-only model.
If your result comes back low, ZAVA’s own guidance is that a repeat test after roughly 4 weeks is recommended before seeing a GP or specialist to discuss treatment, it doesn’t automatically escalate you into a ZAVA-run treatment pathway for a first low result, which is a more conservative approach than some competitors.
Sample Collection Process
- Complete a brief online medical questionnaire before your kit is dispatched
- Kit arrives with instructions for a home capillary (finger-prick style) sample
- Post the sample back to ZAVA’s UK-accredited partner laboratory
- Results and doctor’s advice are typically ready within 2–3 days of the lab receiving your sample
- If you’re already on prescribed testosterone treatment and testing to monitor levels, ZAVA advises checking with your doctor on the best time of day to sample, as this can vary depending on your treatment type
Pricing Breakdown
Pricing varies slightly depending on which ZAVA-branded storefront you order through (ZAVA’s own site, or partner fronts like Asda Online Doctor), typically landing in the low-to-mid £50s for the test kit alone. This sits meaningfully above lab-only competitors — Medichecks’ single-marker test starts around £19, less than half ZAVA’s price for what is, in terms of raw lab output, a comparable total-testosterone-only result. The premium reflects the online-doctor service wrapped around the test, not a difference in what’s measured.
Accuracy and Reliability Notes
The underlying lab analysis is processed through ZAVA’s UK-accredited partner laboratory, and the collection method (finger-prick style capillary sample) carries the same general considerations as any home test: morning collection is advised, and avoiding recent contact with testosterone gels or creams on the sampling hand is standard good practice, though ZAVA’s own public guidance is less detailed on contamination risk than some competitors’ product pages.
Company Reputation
ZAVA (formerly DrEd) is an established online doctor and prescribing service operating across several UK storefronts, including its own branded site and white-label partnerships such as Asda Online Doctor. Independent reviews are generally positive on service quality and doctor responsiveness, though price is a recurring point of friction in customer feedback, with some users noting cheaper alternatives elsewhere for comparable medication or testing. Worth knowing before you order: because ZAVA is a prescribing service as well as a test provider, a low result that leads to a treatment conversation will naturally be discussed within ZAVA’s own service, not necessarily a conflict of interest in the way a company-owned TRT clinic would be, but not a fully independent third party either.
Who It’s a Good Fit For
- You want your test and any resulting prescription conversation handled by the same regulated service, without switching providers
- You’re already on prescribed testosterone treatment and want a straightforward way to test and discuss repeat prescriptions
- You value a doctor’s review being genuinely built into the core service, not an add-on
Who It’s Less Suited To
- Anyone price-sensitive who mainly wants a low-cost baseline reading, lab-only providers are meaningfully cheaper for the same total-testosterone marker
- Anyone who wants SHBG or free testosterone included from the outset, rather than total testosterone alone
- Anyone who’d prefer their test provider and prescribing service to be entirely separate
How It Compares
Against Medichecks’ £19 single-marker test, ZAVA is considerably more expensive for what is, in lab terms, a comparable total-testosterone-only result. The difference is the online-doctor service wrapped around it. Against Randox’s £46 Quickdraw panel, ZAVA offers a narrower single-marker result at a higher price, though with a more conservative low-result pathway (repeat test before referral, rather than an immediate upsell). See our full comparison of UK testosterone test kits for the complete picture.
Bottom Line
ZAVA suits someone who wants a single, doctor-reviewed test folded into a broader online prescribing relationship, particularly if ongoing treatment is a likely next step. If your main priority is the cheapest possible baseline reading, or the broadest hormone panel for your money, lab-only competitors offer better value on both counts.
FAQ
What exactly does the ZAVA testosterone test measure?
Total testosterone only, SHBG and free testosterone are not included in the base test.
Is ZAVA a lab, or an online doctor service?
ZAVA is primarily an online doctor and prescribing service; your sample is processed by a UK-accredited partner laboratory, not an in-house ZAVA lab.
What happens if my result comes back low?
ZAVA’s guidance recommends a repeat test after around 4 weeks, followed by a discussion with your GP or a specialist about next steps, rather than an immediate treatment pathway.
Can I use this test to monitor existing TRT?
Yes, if you’re already on prescribed testosterone treatment, ZAVA can support repeat testing and prescription conversations, though timing of your sample should be checked with your prescribing doctor as it can vary by treatment type.
Why is ZAVA more expensive than lab-only testosterone tests?
The price reflects the online consultation and doctor review built into the service, rather than a difference in the underlying lab analysis, which measures the same total testosterone marker as cheaper single-marker competitors.
