USD 350 · at-home stool sample
- Species-level DNA sequencing
- Clinical lab in Santiago, Chile
- Reviewed with your physician
- Report in Spanish and English
Three steps, one sample
You collect a stool sample at home. Our partner lab does the sequencing, and your physician helps you act on the results.
Send and analyze
Your sample travels to our partner clinical lab in Santiago, Chile, where the bacterial DNA is sequenced to species level and mapped to diversity, bacterial ratios and functional pathways.
Get results and take action
Your report arrives in your online portal with a 0–100 Health Index, a food plan and a suggested probiotic formula. Retest at 4–6 months to see how your gut has changed.
What your report shows
Seven modules that move from one clear score to the specific bacteria, functions and foods behind it.
Microbiome Health Index
One score from 0 to 100 that sums up diversity, balance, beneficial bacteria and pathogens.
Diversity and richness
How many species you host and how evenly they are spread. More variety means a more resilient gut.
Enterotype
Your dominant ecosystem type, linked to eating habits and inflammation risk.
Bacterial ratios
Firmicutes/Bacteroidetes, Proteobacteria/Actinobacteria and other markers of metabolism and inflammation.
Species of interest
Pro-inflammatory or pathogenic species, and beneficial bacteria you are missing across 13 probiotic genera.
Functional pathways
Butyrate and B-vitamin production, fiber, lactose, gluten and alcohol breakdown, serotonin and GABA.
Your action plan
Foods to increase and reduce, lifestyle steps, a suggested probiotic formula and when to retest.
Dysbiosis: below 60
Vulnerable: 60–69
Healthy: 70–79
Optimal: 80 and above

Questions
Is this a medical diagnosis?
No. The test is a functional-medicine tool that helps you and your physician personalize nutrition, probiotics and lifestyle. It does not diagnose disease or replace a clinical evaluation.
What sample do I need to give?
One stool sample, collected at home with the kit. There is no blood or saliva sample.
Where is my sample analyzed?
At our partner clinical laboratory in Santiago, Chile, which sequences the bacterial DNA in your sample and identifies bacteria at genus and species level.
How long do results take?
Turnaround time will be confirmed with the laboratory before launch. You will get an email when your report is ready in your portal.
Why retest at 4–6 months?
Your microbiome changes with diet, medication and lifestyle. A second test shows whether the food plan and probiotic are working.
Which countries do you ship to?
Costa Rica, Chile and Colombia at launch, with more Latin American countries to follow.
How is my data protected?
Your results are linked to your kit code and shared only with you and the physician you choose. We follow the data protection laws of each country we serve.
