The case for The Specialist

One answer beats years of not knowing.

Many people spend years and a great deal on tests that lead nowhere, while the symptoms stay. The Specialist puts a consultant, comprehensive testing and a nutritionist into one programme, so the cause is found, dealt with, and behind you.

Find the cause

Comprehensive and consultant led, so you stop treating the wrong thing.

A plan that fits you

Built from your results by a nutritionist, not a generic list.

Confirmed, not assumed

Repeat testing at the end shows the plan worked, in your numbers.

Prices are indicative and confirmed at consultation. Microbiome sequencing is used to understand your gut and personalise nutrition, not as a medical diagnosis. The bowel cancer safety check follows a defined clinical pathway, and any result needing further investigation is escalated by a doctor. Tests are arranged only where clinically appropriate.
Why they came to us
I had spent years and a great deal on tests that told me nothing. Here, a doctor actually explained what was going on.

Finally understand your body

A doctor explains exactly what is going on, in plain English, and what to do about it.

Never pay for a test that changes nothing

Evidence led, so every test on your list earns its place, and the rest are left out.

Eat in a way that works for you

A nutritionist turns your results into the meals, fibre and fermented foods that settle your gut.

Free guide

The doctor's gut guide, free.

Sixteen pages on what the science shows, what is worth testing, and the changes that settle most symptoms.

Your guide arrives by email.
The evidence

Everything traces to a source.

Validated tests find real disease

The right stool test separates genuine inflammation from a sensitive gut, so serious conditions are caught and the rest reassured.
NICE DG11. Breath testing, Rezaie et al, Am J Gastroenterology, 2017.

The microbiome is best read deeply, and honestly

Deeper sequencing reads the whole community that shallower tests miss. It is powerful for understanding your gut, and it is not a diagnosis.

Food changes your gut

Fermented foods raise diversity and lower inflammation, and a wide range of plants tracks with a healthier gut. Higher fibre tracks with markedly lower mortality.
Wastyk et al, Cell, 2021. Reynolds et al, The Lancet, 2019.

Some popular tests are not worth doing

IgG food sensitivity testing reflects what you eat, not what harms you, and the allergy bodies advise against it. We do not offer it.
Stapel et al, EAACI, Allergy, 2008.
Questions

Good to know.

How much does a private gut health test cost in London?+
Our doctor-led programmes start at £695 for validated stool and blood testing with a written plan, £1,595 for a programme that adds full microbiome sequencing and a registered nutritionist, and £3,950 for a comprehensive, consultant-led investigation with follow-up testing.
What is the best gut health test?+
The most useful approach combines validated clinical tests, such as faecal calprotectin to tell inflammation from a sensitive gut, with microbiome sequencing for context, all read by a doctor. A test on its own is only useful if a clinician turns it into a plan.
Is a microbiome test a medical diagnosis?+
No, and we will never present it as one. Microbiome sequencing helps us understand your gut and personalise your nutrition. For diagnosis we use validated clinical tests, read by a doctor.
Do you offer food intolerance or leaky gut testing?+
We do not offer IgG food sensitivity panels or leaky gut scores. The evidence does not support them, and the allergy bodies advise against IgG food testing.
Do I need to visit the clinic?+
No. Testing is done at home and your results are explained by phone or video, so the programme fits around you. In-person appointments are available if you prefer.
