Hormone testing used to be a side request bolted onto a consultation. Now it is often the first thing a patient asks for when they land on a clinic's site, and the clinics doing it well treat the panel, the collection route and the review step as one connected decision, not three separate ones.
Why hormone testing has become a core part of the clinic offering
Once a clinic can run a blood test at all, hormone panels are usually the first thing patients ask for: tiredness, low mood, changes around midlife and fertility worries all tend to lead a patient to search for a hormone test before they search for a doctor. Our guide to adding a private blood testing service covers the build-out; this one is about which panels to put in front of patients once that service exists.
The operational challenge is restraint. A clinic that offers every hormone marker under the sun ends up with results nobody has a protocol for. A clinic that picks a short, well-defined set of panels, each with a clear next step attached, builds something it can actually run at scale.
The panels patients actually ask for
Most demand clusters around a handful of panels rather than a long menu:
- Thyroid function: TSH, usually with free T4 if TSH is out of range; fatigue and weight-change queries are the most common trigger.
- Male hormone panel: total and free testosterone with SHBG, the entry point into a TRT pathway for men who go on to need one.
- Female hormone panel: FSH, LH and oestradiol, useful for fertility and cycle questions as well as the midlife symptoms our menopause care guide covers in more depth.
- Wellbeing add-ons: vitamin D, B12 and ferritin, commonly bundled alongside a hormone panel rather than sold alone.
- Cortisol: worth offering with caution; it is one of the most timing-sensitive markers and needs clear patient instructions and clinician interpretation, not a standalone self-service add-on.
Launching with four or five well-understood panels, each mapped to a pathway, beats a long list that patients cannot read and clinicians cannot action.
Collection routes: match the method to the panel
PExpo connects clinics to national UK laboratory partners by API, with four collection routes patients will ask for:
- Home finger-prick kit: the cheapest and most familiar route, posted out and returned in a prepaid pack.
- Tasso+ upper-arm device: a single button press on the upper arm, a useful alternative for patients who struggle with a finger-prick tube.
- Nurse home visit: a venous sample taken at home, the natural fit for a fuller profile.
- Partner clinic draw: a venous sample taken at a clinic near the patient, where the laboratory's network covers them.
A capillary sample from a finger-prick kit or Tasso+ device is usually fine for a single-marker screen such as TSH. A fuller profile, several markers at once, tends to need a venous sample from a nurse visit or partner clinic draw; let the clinician's protocol decide the cut-off rather than defaulting every patient to the cheapest route.
A hormone panel only earns its place in the service once a clinician reviews every result and an abnormal one is tracked to acknowledgement, not just filed: that is what separates a diagnostic add-on from a liability.
Timing and preparation matter as much as the panel
Several hormones only mean something at the right time of day or cycle day: testosterone is typically measured in the morning, cortisol is highly time-sensitive, and female hormone markers can depend on where a patient is in their cycle or whether they have reached menopause. Our TRT guide sets out the specific morning-sample protocol for testosterone; the general point here is that every hormone panel needs its own timing instructions, not a generic "any time" label.
Build the instructions into the booking step, not into a results email after the fact. Capture a mobile number at checkout and pass it to the lab: kits and visits generate texts and booking calls, and a poorly timed or badly prepared sample is the most common reason a result comes back unusable and has to be repeated at the clinic's cost.
Clinician review and escalation when something is abnormal
Every hormone result should be reviewed by a clinician before the patient sees it, and any result the laboratory flags as abnormal or urgent should be escalated and tracked through to acknowledgement, not left sitting in an inbox. That is as true for a routine thyroid screen as it is for a male or female hormone panel.
Clinical review is also where the service earns trust: a raised marker does not always mean treatment on this platform. Sometimes the right outcome is a referral back to the patient's GP, a repeat test at the correct time, or reassurance that the result sits within a normal range for their age and circumstances. A pathway that only knows how to sell the next product is not a diagnostic service.
The best hormone panel is the one your clinicians can act on, not the one with the most letters on the report.
When a hormone blood test is not the right first step
Not every symptom needs a blood test before a decision can be made. NICE guidance (NG23) on menopause diagnosis, for example, generally does not recommend FSH testing in women over 45 with typical symptoms; the diagnosis can usually be made on history alone, with testing reserved for atypical presentations or younger women. Our menopause care guide goes further into that distinction.
The same discipline applies across the board: a clinic that only orders a test when the result will change the clinical decision looks more credible to the GPhC, the CQC and the ASA than one that sells a panel to every visitor as a matter of routine. Pressuring patients toward testing they do not need is also the kind of claim the ASA's CAP Code takes a dim view of in advertising.
How PExpo supports hormone testing for clinics and brands
PExpo runs hormone blood testing as a core service: our API connects clinics to national UK laboratory partners across all four collection routes, home finger-prick kits, the Tasso+ device, nurse home visits and partner clinic draws where the laboratory's network covers the patient. Every result is reviewed by a clinician before release, and any result the lab escalates as abnormal is tracked to acknowledgement.
Clinics with their own prescribers can create a clinic account and start offering panels within weeks; brands without clinical staff can launch the same testing on our white-label network. See the diagnostics page for the full list of panels and routes.
Hormone testing rewards clinics that keep the menu short and the pathway clear: a handful of panels, a collection route that fits each one, and a clinician on every result. Our guides to starting a TRT clinic and menopause care beyond HRT go deeper on the two busiest hormone pathways, and the pricing page sets out how testing fits into a clinic or brand plan.
Frequently asked questions
Which hormone blood tests should a UK telehealth clinic start with?
Most clinics do well starting with thyroid function, a male hormone panel and a female hormone panel, often alongside wellbeing add-ons such as vitamin D or B12. Pick panels you have a clear next step for, rather than offering every marker available.
Do hormone blood tests need a venous sample?
It depends on the panel. A single marker such as TSH is often fine from a finger-prick kit or the Tasso+ device, while fuller profiles with several markers typically need a venous sample from a nurse home visit or partner clinic draw. The clinician's protocol should set the cut-off, not the patient's preference alone.
Who reviews hormone test results before a patient sees them?
A clinician should review every hormone result before it reaches the patient, and any result a laboratory flags as abnormal or urgent should be escalated and tracked through to acknowledgement. Patients should not be left to interpret a hormone panel without that review.
