Concierge FIT bowel screening · London
Private FIT bowel screen in London, the definitive screening stool test.
A simple at-home stool test that detects tiny amounts of blood — the definitive screening test for bowel cancer, with a direct pathway to colonoscopy if positive.
Why patients choose us
- 01
The definitive screening test
FIT is the modern, evidence-based stool test for bowel cancer — far more accurate than the old FOBT kits and endorsed by NICE.
- 02
Done from home, no diet changes
A single sample, posted back in the discreet return envelope. No food or medication restrictions to prepare.
- 03
A direct pathway if positive
A positive FIT means a colonoscopy is needed — we book you straight into a consultant gastroenterologist, without delay.

The problem
Bowel cancer screening should be simple and quick.
NHS FIT screening is excellent — but only from age 60 (moving to 50), and only every two years. People often want to screen earlier, sooner, or repeat outside that window, with a consultant available if the result is positive.
-
Too young for NHS screening?
FIT from age 50, or earlier where a family history or symptoms warrant it — arranged privately, at home, within days.
-
Missed an NHS invitation?
A quick private FIT gets you back on track without waiting for the next NHS cycle to come round.
-
Symptoms that need triage?
A quantitative FIT helps prioritise onward investigation — with a consultant gastroenterologist ready if the result is positive.
The journey
From enquiry to result — what happens, in order.
One consultant gastroenterologist available from the first message to the result and any onward colonoscopy — usually within a week.

A positive FIT is booked directly with a consultant gastroenterologist for colonoscopy. Negative results include a clear repeat interval.
Typical end-to-end: 5–10 days. Positive result to colonoscopy: within days.
When to test
The reasons people come to us.
Different reasons need different pathways — routine screening, symptom triage, family history and surveillance are all handled a little differently.
-
Bowel cancer screening
Age 50–74 privately, or 60–74 on the NHS — the routine screening test recommended for asymptomatic adults.
-
Symptomatic screening
Change in bowel habit, abdominal pain or unexplained tiredness — FIT triages who needs colonoscopy first.
-
Family history of bowel cancer
A first-degree relative diagnosed young. FIT supplements — never replaces — a specialist family-history assessment.
-
Distinguishing IBS from IBD
Alongside faecal calprotectin, FIT helps separate benign IBS from inflammatory bowel disease and other causes.
-
Age-related routine screening
A sensible baseline from your fifties onward, especially if you have missed NHS screening invitations.
-
Post-polypectomy surveillance
A quick interval check after polyp removal, per your gastroenterologist’s recommended schedule.
-
Positive FIT → colonoscopy
A positive result is a signal for prompt colonoscopy — we arrange it directly with a consultant gastroenterologist.
-
Red flags: bleeding or weight loss
Rectal bleeding or unexplained weight loss needs an urgent GP review regardless of a FIT result — do not wait.

Symptom-triggered FIT
For change in bowel habit, iron-deficiency anaemia or abdominal pain — used to prioritise onward investigation.
-
Repeat FIT
A surveillance test after a previous FIT or as part of an interval plan set by your gastroenterologist.
-
Home-collection kit (posted)
Discreet packaging, pictorial instructions, a pre-paid return envelope and tracked handling from lab receipt onward.

What to know
The practical things worth knowing before you test.
Collection, timing, and the difference between a screening result and a definitive cancer exclusion.
-
Home collection, at your own pace
The kit is posted to you and returned by pre-paid envelope. There is no clinic visit needed for the sample itself.
-
Sample within a few days of arrival
Once the kit arrives, take and return your sample within the timeframe printed on the instructions — usually 3 days.
-
No dietary restriction
Unlike the older FOBT (guaiac) tests, FIT is not affected by red meat, vitamin C or most medications. Eat normally.
-
Avoid contamination
Keep the sample away from urine and toilet water — both can affect the result. The kit includes a paper catch sheet to help.
-
Take one sample only
A single sample from a single bowel motion is all that is needed — more is not more accurate for FIT.
-
Pregnancy is safe
The test is a laboratory analysis of a stool sample. There are no exposures, medications or procedures involved.
-
Not a 100% cancer exclusion
A negative FIT does not rule out bowel cancer entirely — a small number of cancers do not bleed enough to be detected.
-
Positive results need colonoscopy
A positive FIT is a signal, not a diagnosis. Colonoscopy is needed to look for the source of the blood.
-
Repeat as recommended
For screening we repeat every two years by default — your gastroenterologist may recommend a different interval.
Reading your report
A FIT report is just one number — with a plan.
Whatever the value, the report follows the same four parts — read the impression first.
A quiet reminder
A negative FIT is not a 100% exclusion of bowel cancer — red-flag symptoms still need a specialist review.
If you want us to talk you through your report before deciding what to do next, just ask.

Routine bowel cancer screening is generally self-funded; where symptoms are being investigated we confirm cover with your insurer.
Frequently asked
Everything we get asked about the FIT bowel screen.
Quick, plain answers on what FIT measures, thresholds, cost, collection, turnaround and what a positive result means.
-
What does a FIT test actually measure?
FIT (faecal immunochemical test) is a quantitative laboratory test for tiny amounts of human haemoglobin in a stool sample. Because bowel polyps and cancers can bleed intermittently, detecting even minute blood traces is a highly sensitive way to flag people who need a colonoscopy.
-
How is FIT different from the old FOBT tests?
The older guaiac FOBT tests reacted to any peroxidase activity, including red meat and vitamin C, needed multiple samples and had a high false-positive rate. FIT is antibody-based, so it is specific to human haemoglobin, needs only a single sample and does not require any dietary restriction. It is the test the NHS Bowel Cancer Screening Programme now uses.
-
What threshold makes a FIT positive?
FIT is quantitative — it reports a number in micrograms of haemoglobin per gram of faeces. In the UK a common positive threshold is 10 μg Hb/g in symptomatic pathways, and higher for asymptomatic screening. Your report explains which threshold was used and what your specific value means.
-
How much does a private FIT test cost?
A single at-home FIT is typically £45–£120. Adding a private GP review takes the package to £150–£300. A fuller stool panel that adds calprotectin and other markers runs £200–£450. Firm figures come back within one working day.
-
How do I collect the sample?
The kit contains a small sample bottle, a paper catch sheet and pictorial instructions. You take one small scraping from a single bowel motion, avoiding contact with urine or toilet water, seal the bottle back into the return envelope and post it the same day. It takes a couple of minutes.
-
How long do the results take?
Results are usually available within 3–7 days of the laboratory receiving your sample, delivered by a secure link with a plain-English interpretation. Bundled stool panels take a little longer, at 5–10 days.
-
What happens if my FIT is positive?
A positive FIT means human haemoglobin was detected above the reporting threshold. It is not a cancer diagnosis — most positive FITs are due to benign causes such as polyps or haemorrhoids — but it does mean a colonoscopy is needed to look for the source. We arrange this directly with a consultant gastroenterologist.
-
Does a negative FIT rule out bowel cancer?
A negative FIT is reassuring but it is not a 100% exclusion — a small number of bowel cancers bleed too little, or too intermittently, to be picked up. If you have red-flag symptoms such as rectal bleeding, weight loss or a persistent change in bowel habit, you still need a specialist review regardless of a negative FIT.
-
Is FIT safe in pregnancy?
Yes. The test is a laboratory analysis of a stool sample, so there are no exposures, medications or procedures for you or the baby. If you have symptoms during pregnancy that prompted testing, your obstetric team should be informed of the result.
-
When should I see a GP urgently instead of doing a FIT?
If you have visible rectal bleeding, unexplained weight loss, a persistent change in bowel habit for more than a few weeks, iron-deficiency anaemia, or a strong family history of bowel cancer at a young age, you need an urgent GP review — FIT is not a substitute for that assessment.
