We often get asked: Can you test other things in the same stool sample? Below is an overview of common stool test types and what InnerBuddies does and does not provide.
Our gut microbiome test uses DNA sequencing to analyze your gut bacteria and translates the results into personalized nutrition advice, food diary and supplement suggestions.
Some providers test a fixed list of about 20 to 40 bacteria using a panel approach. It is often cheaper, but provides a more limited picture than DNA sequencing.
Detection of parasites via microscopy or PCR, typically ordered via a clinician or lab for specific symptoms or travel history.
Marker for intestinal inflammation. Typically requested via a clinician for medical triage and interpretation.
Screening test for blood in stool, usually part of a preventive or medical pathway via a healthcare provider.
Targeted testing for specific pathogens, often relevant for acute symptoms.
Markers such as elastase or fat residue (lab dependent), sometimes used when digestion issues are suspected.
Some advanced programs use shotgun metagenomics to profile microbial DNA in more detail. InnerBuddies offers this as part of its Gut Health Operating System for B2B customers. It is not included in the consumer (B2C) test sold on the InnerBuddies website.

Not every stool test answers the same question. A budget panel can be useful for a quick, limited snapshot. But if you want to understand your gut flora in more depth and what to do next, a microbiome test based on DNA sequencing is typically more informative.
Tip: Choose a test based on your goal. For medical diagnostics, a healthcare provider is typically needed. For gut microbiome insights and practical guidance, InnerBuddies is the better fit.
Note: InnerBuddies focuses on a microbiome test and personalized guidance. For medical diagnostics such as inflammation markers, occult blood, or pathogens, a healthcare provider is typically required.

Microbiome diversity refers to the richness and balance of different bacterial species in your gut ecosystem. A diverse microbiome is generally associated with resilient digestion, stronger immune function, better metabolic flexibility, and reduced risk of chronic inflammation. Low diversity, often detected through a gut microbiome diversity test, may correlate with gut imbalance, IBS-like symptoms, reduced microbial resilience, and less stable gut health over time.
Positive bacteria are microbial species scientifically associated with beneficial functions such as fiber fermentation, butyrate production, gut barrier support, and anti-inflammatory effects. These bacteria help maintain a stable gut environment and are often linked to better digestive comfort, metabolic health, and long-term microbiome stability.
In contrast, negative bacteria are species that, when relatively overrepresented, may be associated with gut dysbiosis, inflammation, reduced microbial diversity, or unfavorable metabolic activity. Importantly, microbiome balance—not the presence of a single species—determines overall gut health.
Microbial pathways represent the functional potential of your microbiome—what your bacteria are capable of doing metabolically. These include fiber fermentation, vitamin synthesis, short-chain fatty acid production, bile acid metabolism, and inflammation-modulating pathways. Pathway analysis transforms microbiome sequencing into actionable biological insight, forming the basis of personalized gut health recommendations.
A Healthy Cohort refers to a scientifically defined reference population with microbiome patterns associated with stable gut health, good metabolic function, and lower inflammatory signatures. Comparing your microbiome against a healthy cohort enables deeper interpretation beyond simple bacterial counts.
The Target Group Longevity represents microbiome patterns commonly observed in individuals with long-term metabolic resilience, stable inflammation control, and healthy aging trajectories. Aligning your microbiome toward this profile is a core objective of personalized microbiome optimization and preventive gut health strategies.

The Gut Microbiome Health Index (GMHI) is a composite score derived from microbiome composition patterns observed in large population datasets. It reflects how closely your microbiome profile aligns with patterns typically seen in healthier gut ecosystems versus dysbiotic profiles. A higher GMHI generally indicates stronger microbial balance, while a lower score may suggest areas where personalized nutrition and lifestyle adjustments could support improvement.
InnerBuddies has an exclusive IP license from EAFIT University in Latin America to use their GMHI index in its platform.
Your nutrition recommendations are generated using advanced analysis of your gut microbiome composition, bacterial diversity, and functional metabolic pathways, combined with insights from your 3-day food diary. InnerBuddies links real dietary intake data with microbiome functional pathway activity to understand how your gut bacteria interact with nutrients such as fiber, polyphenols, fats, and carbohydrates. This unique data-driven approach enables precise, microbiome-based nutrition guidance tailored to your individual microbial profile. All recommendations are developed within evidence-based nutritional frameworks and reviewed under the professional boundaries established by our dietician team, ensuring safe, practical, and personalized dietary advice that supports gut health, microbial balance, and metabolic function.
This is exclusive InnerBuddies IP.
Your supplement recommendations are based on scientifically validated probiotic strains and targeted prebiotic fibers supported by clinical research. We analyze your gut microbiome profile to identify beneficial bacteria that may be underrepresented and map these findings to specific probiotic strains and complementary prebiotics known to support microbial balance. In addition, we consider the documented objectives and target populations for which each probiotic strain has been studied, helping align recommendations with your individual microbiome characteristics and nutritional context. This strain-level, evidence-based approach focuses on precision rather than generic probiotics, supporting beneficial bacteria, gut microbiome stability, and digestive function. All suggested probiotics and prebiotics are selected based on scientific evidence and microbiome compatibility.

Answers to the most common questions about the InnerBuddies gut microbiome test, methodology, and privacy.
A gut microbiome test is a stool-based laboratory analysis that examines the trillions of bacteria living in your digestive system. Our at-home microbiome test uses advanced DNA sequencing to measure bacterial diversity, beneficial and harmful microbes, and overall gut health. The results help you understand digestion, metabolism, immunity, and how your microbiome may influence symptoms like bloating, low energy, or gut imbalance.
Our microbiome test kit is simple to use at home. You collect a small stool sample, send it to our certified laboratory using the prepaid return package, and we perform DNA sequencing of your gut bacteria. Within a few weeks, you receive a detailed microbiome report with personalized nutrition and lifestyle recommendations to improve your gut health.
Our gut microbiome analysis measures bacterial diversity, key beneficial bacteria, potentially harmful bacteria, and important microbial functions linked to digestion, metabolism, and inflammation. The test also evaluates your overall gut health score and identifies areas where your microbiome may be imbalanced (dysbiosis).
Our microbiome test uses validated DNA sequencing technology (16S rRNA sequencing) performed in ISO-certified laboratories. This method is widely used in scientific microbiome research and provides a reliable overview of your gut bacterial composition. While microbiome testing is not a medical diagnostic tool, it offers valuable insights for optimizing nutrition and gut health.
A gut microbiome test is helpful for people who experience digestive issues such as bloating, irregular bowel movements, or gut discomfort, as well as individuals interested in optimizing their health, metabolism, and immune function. Many people use microbiome testing to better understand how diet, lifestyle, and supplements affect their gut bacteria.
A microbiome test cannot diagnose medical conditions, but it can reveal imbalances in gut bacteria that are often associated with digestive symptoms such as bloating, irregular digestion, and gut discomfort. Understanding your microbiome may help guide dietary and lifestyle changes that support gut balance and overall digestive health.
The gut microbiome changes over time due to diet, lifestyle, antibiotics, and environment. Many people repeat a microbiome test every few months to track progress and see how their gut bacteria respond to nutrition and lifestyle changes. Longitudinal testing provides deeper insight into improving gut health over time.
Our microbiome test combines advanced DNA sequencing, scientific gut health analysis, and personalized nutrition guidance. Instead of only showing raw bacteria data, we translate your microbiome into clear insights and actionable recommendations designed to help improve digestion, metabolism, and overall gut balance.
After your sample arrives at our laboratory, microbiome sequencing and analysis typically takes 3 to 4 weeks. Once complete, you will receive an email and will receive access to your full gut microbiome report online, including your gut health score, bacterial diversity, and personalized recommendations.
Improving your gut microbiome usually involves dietary changes, increasing fiber intake, consuming prebiotics and probiotics, reducing processed foods, and maintaining a healthy lifestyle. Your personalized microbiome report provides tailored recommendations based on your unique gut bacteria composition.
Microbiome testing provides a snapshot of gut bacteria at the time of sampling. Results can vary with diet, recent illness, travel, medications, and sample collection. It is not a diagnostic test and should not replace medical evaluation for persistent or severe symptoms.
A microbiome test does not diagnose disease, does not replace colonoscopy or clinical labs, and typically does not directly measure viruses or parasites unless explicitly included. It focuses on bacterial patterns and gut health insights for nutrition guidance.
Yes. Antibiotics can significantly alter gut bacteria. For the most meaningful baseline, it’s often recommended to avoid testing immediately after antibiotics and to consider retesting later to track recovery (follow your clinician’s advice if you have a medical condition).
Samples are analyzed in a ISO-certified professional laboratory in Austria using standardized sequencing workflows (Illumina MiSeq) and quality-control steps. The goal is reproducible measurement of bacterial composition and diversity from stool samples.
Reliability depends on correct sample collection, safe transport, laboratory QC, and validated bioinformatics. We use standardized protocols and quality checks to detect insufficient sequencing depth or low-quality reads before producing your report.
16S sequencing is widely used in scientific research for profiling gut bacteria. It is best suited for microbiome composition and diversity insights, not as a stand-alone medical diagnostic tool.
Recommendations are based on your microbiome profile combined with your questionnaire and your 3-day food diary. The output focuses on actionable nutrition and supplement guidance aligned with current microbiome science.
No. Recommendations are educational and intended for wellness and nutrition support. If you have a medical condition, are pregnant, take medication, or have severe symptoms, you should consult a qualified healthcare professional before making major changes.
