Concierge stool testing · London
Private stool tests in London, from FIT to microbiome analysis.
From FIT bowel-cancer screening to calprotectin for IBD — accurate stool testing run in UKAS-accredited labs, with sterile home-collection kits.
Why patients choose us
- 01
We explain, not just report
A clinician talks you through what a positive FIT or raised calprotectin actually means — before you go looking online.
- 02
No bundle upselling
A focused panel that answers your question — not a five-hundred-pound microbiome kit if a FIT is what you need.
- 03
Accredited labs only
UKAS-accredited laboratories, results reviewed by a consultant pathologist, onward referral where indicated.

Prices vary by laboratory, how many markers are included, and how quickly you need the results. We come back with a firm quote within one working day.
The problem
A raised marker is not a diagnosis.
Plenty of websites will sell you a stool kit. Knowing which test to run, and what to do with a positive FIT or a raised calprotectin, is the part that matters. That is what we do.
-
Not sure which panel?
Tell us the symptoms and we suggest the test that answers them — not the biggest bundle on the shelf.
-
Worried about a result?
We explain a positive FIT or raised calprotectin, and arrange the right onward step rather than leaving you to Google it.
-
Want it done at home?
Every panel we arrange uses a sterile home-collection kit posted to you, with pre-paid return.

Off to the lab

After
Results reviewed
Results are checked by a consultant pathologist, usually within 3–14 days depending on the panel.

After
We explain them
We talk you through the findings and arrange onward gastroenterology or urgent GP review when needed.
Typical end-to-end: 1–2 weeks. Urgent cases: a few days.
What it shows
Find the panel that matches the symptom.
Stool tests answer very different questions. These are the reasons people come to us most.
-
Bowel cancer screening (FIT)
Detects trace blood in the stool — the first-line test for suspected bowel cancer in primary care.
-
IBD vs IBS (calprotectin)
Faecal calprotectin distinguishes inflammatory bowel disease from irritable bowel syndrome.
-
Chronic diarrhoea investigation
A structured panel to work up persistent, unexplained diarrhoea rather than guessing.
-
Parasites and travel illness
Ova, cysts and parasite testing for post-travel diarrhoea and persistent gut symptoms.
-
C. difficile infection
Toxin testing after antibiotics or hospital admission, when diarrhoea will not settle.
-
H. pylori (stool antigen)
Non-invasive detection of the bacterium behind many cases of dyspepsia and peptic ulcer.
-
Microbiome analysis
A comprehensive stool panel for those wanting a broader look at the gut ecosystem.
-
Red flag symptoms
Rectal bleeding or unexplained weight loss? These need urgent GP review, not a home kit — we will say so.
Available panels
The stool panels we arrange most.
What each option is actually for.
-
FIT (faecal immunochemical test)
Quantitative test for occult blood in stool — the standard bowel cancer screen.
-
Faecal calprotectin
Marker of gut inflammation used to distinguish IBD from IBS.
-
Stool culture + sensitivities
Identifies bacterial causes of infective diarrhoea and appropriate antibiotics.
-
Ova, cysts and parasites
Microscopy for parasitic causes of gut infection, particularly after travel.
-
C. difficile toxin
Detects toxin-producing C. difficile in antibiotic-associated diarrhoea.
-
H. pylori stool antigen
Non-invasive confirmation of active H. pylori infection.
-
Faecal elastase (pancreatic function)
Measures pancreatic enzyme output for suspected exocrine insufficiency.
-
Comprehensive microbiome panel
Broader analysis of gut flora and diversity for patients wanting a fuller picture.
Our vetted London network

-
Onward referral to gastroenterology when the findings need it
Preparation and practicalities
Simple to collect — if you follow a few rules.
Stool tests are non-invasive and safe, but preparation matters — diet, contamination and timing can all change the result. We tell you exactly what to do.
-
Sample collection at home
A sterile kit is posted to you with clear instructions. Most people find it straightforward and private.
-
Keep the sample clean
Avoid contamination with urine or water from the toilet bowl — the kit includes a collection device to help.
-
Diet before a FIT
Some FIT assays advise avoiding red meat for three days beforehand. We tell you exactly what applies.
-
Medication
Continue your usual medication unless we tell you otherwise. Iron and anti-inflammatories can affect some tests.
-
You may need more than one sample
Culture and parasite tests sometimes require samples over several days to catch intermittent shedding.
-
Pregnancy
Stool tests are safe in pregnancy. Some reference ranges shift and we interpret accordingly.
-
Results interpretation matters
A raised calprotectin or positive FIT does not equal disease — context and repeat testing often matter.
-
Storage and return
Return the sealed sample promptly using the pre-paid envelope. Refrigerate briefly if there is a delay.
-
Abnormal FIT
A positive FIT triggers the two-week wait colonoscopy pathway. We arrange onward referral quickly.
Reading your report
A stool test report can look intimidating. It isn’t.
However many markers are run, the report follows the same four parts.
A quiet reminder
Read the impression first — the rest is the working.
If you would like us to talk you through the report before any follow-up, just ask.
- 01 Header
Your details and the indication
Your details, which panel was requested, and the clinical question behind it.
- 02 Technique
Which panel was run
The specific assays used — FIT, calprotectin, culture, PCR, microscopy — and the laboratory that ran them.
- 03 Findings
Each marker, with reference range
Every marker reported alongside its reference range, with anything outside the range clearly flagged.
- 04 Impression
The conclusion: read this first
What the results mean — reassurance, repeat sampling, further tests, or urgent referral.
Recognised by major UK insurers
Cover varies by policy. Where testing is medically indicated we confirm cover with your insurer before booking.
Frequently asked
Everything we get asked about stool tests.
Quick answers on cost, sample collection, referrals, microbiome kits and when to see a GP urgently.
-
What does a FIT test show?
FIT (faecal immunochemical test) looks for tiny amounts of blood in the stool that are invisible to the eye. It is the first-line screening test for bowel cancer in primary care and can also flag other bowel conditions that need investigation.
-
What is the difference between calprotectin and an IBS test?
Faecal calprotectin measures gut inflammation. A raised result points to inflammatory bowel disease (Crohn’s or ulcerative colitis) and usually leads to colonoscopy. A normal result makes IBS much more likely, saving unnecessary investigations.
-
How much do private stool tests cost in London?
A FIT costs £45–£120, calprotectin £75–£180, and a comprehensive microbiome panel £200–£500. We quote a firm figure within one working day once we know what you need.
-
Do I need a referral?
Most stool tests accept self-referral. For panels that need clinical interpretation — or where symptoms suggest urgent investigation — we can arrange a fast-track private GP or consultant gastroenterologist.
-
How do I collect the sample at home?
A sterile kit arrives by courier with a collection device, sample tube and pre-paid return envelope. Instructions are plain English. Avoid contamination with urine or water and post it back the same day.
-
How many samples do I need?
A FIT or calprotectin usually needs one sample. Culture and parasite panels sometimes require samples on separate days to catch intermittent shedding — the lab will tell us if that applies.
-
Are microbiome tests evidence-based?
Microbiome panels can give useful insight into gut diversity, but the clinical evidence is still developing. We are honest about what the results can and cannot tell you, and never sell them as a diagnostic test.
-
How quickly will I get my results?
FIT, calprotectin and H. pylori antigen results are typically back in 3–7 days. Culture and comprehensive microbiome panels take 7–14 days. We share the timeline when you book.
-
Can I do a stool test in pregnancy?
Yes — stool tests are safe in pregnancy. Some reference ranges shift slightly and we interpret results with that in mind.
-
When should I see a GP urgently instead?
Rectal bleeding, unexplained weight loss, a persistent change in bowel habit or nocturnal symptoms need urgent GP review — not a home kit. We will tell you if that is the right route rather than take your money.
