The ecosystem
living inside you

A stool sample allows the composition and bacterial diversity of your gut to be characterised. Not a list of bacteria. A portrait of an ecosystem.

What the microbiome is

A community that works with you

The gut microbiome is the community of bacteria that lives in the intestine. It breaks down components of food the body cannot digest on its own - such as dietary fibre - and converts them into substances with a positive effect on the body, such as short-chain fatty acids.

This community is not just digestive. The report highlights that more than 70% of the immune system is located in the gut and is supported by the bacteria living there.

Composition varies between people and over time, influenced by diet, medication, age, physical activity and health status.

Diversity, not a head count

What matters is how many different species are present and how evenly they are distributed - not just which ones show up.

Fibre is raw material

Beneficial bacteria ferment fibre and resistant starch. What you eat determines what the community has to work with.

Described pathways, not certainties

Research links the microbiome to immunity, metabolism, skin and mood.

What the test analyses

Six chapters, from the ecosystem down to the individual genus

Each chapter cross-references the composition found with reference ranges and profiles from reference populations.

The overall state of the ecosystem: how varied it is, how balanced it is and what long-term dietary pattern characterises it.

Microbial diversity

Calculated with the Shannon index, which combines two separately reported values: species richness (how many different species are in the sample) and species evenness (how balanced the distribution between them is). The report describes diversity as the most important parameter for analysing microbiome health.

Dysbiosis index

Quantifies the degree of ecosystem imbalance. The report notes it is useful for monitoring changes over the course of treatments or dietary adjustments.

Enterotype

Classification of the microbiome into three dominant bacterial groups, associated with long-term dietary patterns.

Enterotype 1
Bacteroides

Associated with a diet rich in animal-based foods.

Enterotype 2
Prevotella

Associated with a plant-based diet rich in fruit, vegetables, legumes and whole grains.

Enterotype 3
Ruminococcus

Associated with a mixed diet rich in complex carbohydrates, including fibre.

Reading your result

There are no good and bad bacteria

Almost nothing in the report is read in isolation. Each value is positioned against a reference range and only makes sense alongside diversity, the overall balance of the ecosystem and your context - diet, medication, symptoms and lifestyle.

What you will receive

Exactly what is included

A complete digital report, the raw data layer behind it, and the translation of that data into decisions you can actually make.

An 8-chapter digital report

Every parameter comes with its value, the reading scale, and an "additional information" block explaining what is being measured.

  • Indices and scores: diversity (Shannon), richness, evenness, dysbiosis index, enterotype and inflammatory potential
  • 14 tendency parameters - immunity, inflammation, skin, weight, leaky gut, IBS, SIBO, gluten, mental and physical well-being, blood sugar, blood pressure, liver and thyroid
  • Bacteria lists by function: probiotic, mucin-producing, butyrate-producing and sulphate-reducing
  • F/B ratio and a full genus table with frequency and reference range
  • A recommendations chapter organised by the same themes, with a consolidated closing summary

Recommendations you can apply

Each recommendation comes with an explanation of why, plus a practical block with concrete implementation suggestions.

  • Dietary strategies aligned with your enterotype and profile
  • Suggestions for fibres, prebiotics and fermented foods
  • Lifestyle strategies: movement, alcohol, caffeine, ultra-processed foods
  • Recipes aligned with the areas to work on

Integrated into Lyvoo

Results do not sit in an isolated PDF: they feed into your plan, cross-reference your other health data, and stay available for comparison at your next reassessment.

How it works

From home collection to report

A single stool sample, collected at home. All processing is laboratory-based and bioinformatic.

1
You receive the kit

The collection kit arrives at your home, with instructions for collection, storage and return.

2
You collect the sample

A stool sample, following the kit instructions. No travel and no blood draw.

3
Laboratory analysis

The sample is assigned its own ID and processed in the laboratory.

4
Results in Lyvoo

The report becomes available on the platform, integrated into your plan and ready to be compared at your next reassessment.

Limitations and scope

What the test does not do

A microbiome test is valuable precisely because you know where it ends. These are the boundaries stated in the manual itself.

Limitations of the result

These apply to any microbiome analysis, and are described in the report.

  • One sample represents one moment. Composition varies over time with diet, medication, antibiotics, illness, travel and lifestyle.
  • Detecting a microorganism does not imply disease, and not detecting one does not rule out the presence of a disease-causing agent.
  • Other organisms may be present that this test does not detect.
  • Results are tendencies and propensities, not diagnoses. They should be interpreted alongside symptoms, clinical history and other data.
  • Scientific association does not mean causality. The enterotype in particular indicates only a tendency, and the types may overlap.
  • The summary in the recommendations chapter is generated with the help of artificial intelligence, as stated in the report itself.
  • It does not replace diagnosis or medical decision-making. Health decisions should not rest on these results alone.

What this test is not

Different gut tests answer different questions. This one answers a single question.

  • It does not screen for parasites, fungi, viruses or archaea. The analysis covers the bacterial community.
  • It is not a food intolerance test. The gluten sensitivity parameter estimates a tendency from bacterial composition without diagnosing the condition.
  • It does not directly measure intestinal permeability. The leaky gut tendency is inferred from composition, not from a barrier marker.
  • It is not an antibiogram and does not replace established methods for identifying micro-organisms.
  • It is not a stool culture for detecting infectious agents.
  • It does not determine "the right probiotic for you". It quantifies the probiotic groups present and helps assess whether a strategy is warranted, together with a professional.
