Precision and Legacy only
Foundation retains the main annual testing, nutrition and training system without this added layer.
Advanced testing guide
A gut baseline. Not a diagnosis.
Gut microbiome testing adds one view of the microbial community found in a stool sample. Inside the Longevity Programme, it is considered alongside symptoms, medical history, nutrition and the rest of the clinical picture.

In short
Precision and Legacy include gut microbiome testing at the start of each membership year. From the second year, renewal creates a year-over-year comparison. The result does not diagnose a condition on its own.

Guide overview
Use the report as one layer of context, not the answer to every symptom.
Clinical microbiome testing is still developing. The useful question is not whether a report contains many organisms; it is whether the information changes a cautious, practical clinical conversation.One baseline each membership year
A real year-over-year comparison is possible only after renewal into a second year.
No stand-alone diagnosis
Symptoms, history, medicines, diet and other investigations still matter.
What the test adds
The report describes organisms and patterns detected in the submitted sample. It can add context to a broader discussion about symptoms, food pattern and digestive history.
It does not replace a medical assessment, blood testing, imaging or another investigation your doctor considers necessary.
Where it sits in the membership
Gut microbiome testing is included in Precision and Legacy. The sample is collected at the start of every membership year and acts as that year's baseline.
Foundation does not include this layer. Its annual calendar still includes the full panels, priority-marker checks, doctor review, precision nutrition and functional training.
What changes on renewal
Your first year creates a baseline. If you renew, the next annual sample creates a genuine year-over-year comparison.
This is different from the Legacy epigenetic test, which is completed once in the first year and is not repeated on renewal.
What the result cannot claim
- It cannot diagnose a disease by itself.
- It cannot identify one universal ideal microbiome.
- It cannot prove that one food or supplement will solve a symptom.
- It should not be used to stop prescribed treatment.
Clinical interpretation stays cautious.
Microbiome science is developing. The programme uses the report as context, not as a stand-alone answer.
How it informs the next conversation
Your doctor and nutrition professional consider the report with your symptoms, history and current plan. Useful findings may shape questions or nutrition decisions, but changes still need to be practical and clinically appropriate.
For active digestive symptoms, the Lyxaa Gut Health Programmes may be the more direct starting point.
What can affect a sample and its interpretation
A stool sample is one point in time. Recent antibiotics, medicines, supplements, acute illness, major dietary changes, collection conditions and laboratory methods can all matter to interpretation.
- Follow the collection and storage instructions exactly.
- Tell the team about recent antibiotics, medicines and supplements.
- Report a recent infection or major change in diet.
- Do not compare reports from different methods as if they are automatically equivalent.
Questions worth asking about any report
Clinical meaning
Does this finding change a decision when my symptoms and history are considered?
Uncertainty
What can the method detect, and what remains uncertain or unsupported?
Action
Is the next step practical, safe and supported by more than one report line?
Follow-up
Would another clinical test be more appropriate for the concern being discussed?
Common questions
Clear answers before you choose a next step.
Can a microbiome test tell me exactly what to eat?
No. It may add context, but it does not generate one proven diet for every person. Nutrition decisions still need symptoms, history, routine and clinical judgement.
Should I stop probiotics, supplements or medicines before the sample?
Do not stop prescribed treatment on your own. The team will provide preparation instructions and should know about recent antibiotics, medicines and supplements when interpreting the result.
Is this the right page for active digestive symptoms?
The Gut Health Programmes are the more direct starting point for recurring digestive symptoms. The Longevity Programme uses microbiome testing as one annual layer within a wider membership.
