Gut Microbiome Testing

Comprehensive Gut Microbiome Testing Services – Advanced Metagenomic and Metabolomic Profiling for Personalised Health and Clinical Insights

The human gut microbiome is a complex and dynamic ecosystem that plays a pivotal role in health and disease, influencing digestion, immune function, metabolism, and even neurological processes. The increasing recognition of the gut microbiota as a key factor in conditions ranging from inflammatory bowel disease and metabolic syndrome to mental health disorders has driven demand for high‑resolution, clinically actionable gut microbiome testing. However, a meaningful gut microbiome analysis is far more than a simple taxonomic report; it requires a sophisticated, multi‑layered approach that integrates shotgun metagenomic sequencing, strain‑level resolution, functional gene profiling, metabolomic analysis, and host‑microbe interaction modelling. A superficial analysis that only reports relative abundances at the genus level fails to capture the functional potential, the metabolic activity, and the strain‑specific variations that are critical for understanding the host‑microbe dialogue. Our ISO/IEC 17025‑accredited and GMP‑compliant laboratory offers a fully integrated gut microbiome testing platform, covering the entire spectrum from standardised sample collection and nucleic acid extraction to high‑depth sequencing, advanced bioinformatics, and personalised interpretative reporting. We deliver quantitative, traceable data, including species‑level and strain‑level taxonomic profiles, functional gene repertoires, metabolic pathway activity assessments, and, where requested, correlations with host phenotypes and health parameters. Our expert team of microbiologists, bioinformaticians, and clinical scientists provides comprehensive study design, flawless execution, and clear, actionable reports, enabling you to understand the functional status of your gut microbiome, to monitor the impact of interventions, and to make informed decisions for health optimisation or clinical management.

1. The Scientific and Clinical Rationale for Gut Microbiome Testing

Gut microbiome testing serves multiple essential purposes: (a) to characterise the taxonomic composition of the gut microbiota, identifying the presence and relative abundance of bacteria, archaea, fungi, and viruses; (b) to assess the functional potential of the microbiome, by profiling the genes and metabolic pathways that are present; (c) to evaluate the metabolic activity of the community, by measuring the production of short‑chain fatty acids, neurotransmitters, and other metabolites; (d) to monitor the impact of interventions (e.g., dietary changes, probiotic administration, antibiotic treatment) on the gut ecosystem; (e) to identify biomarkers associated with specific diseases or health states; and (f) to support clinical research and personalised health strategies. The choice of analytical approach – whether targeted amplicon sequencing (16S rRNA), whole‑metagenome shotgun sequencing, or metatranscriptomics and metabolomics – must be tailored to the research or clinical question, the required resolution (genus‑level vs. strain‑level), and the need for functional inference. Our service begins with a comprehensive consultation to define the optimal testing strategy, including the selection of the appropriate analysis depth, the development of a customised reporting format, and the integration of any available host‑related data, ensuring both scientific rigor and clinical utility.

2. Our Comprehensive Gut Microbiome Testing Platform – High‑Resolution and Multi‑Omic

We maintain a complete, validated workflow for gut microbiome testing, all performed in a dedicated molecular biology and bioinformatics facility with stringent contamination controls, and using certified reference materials (e.g., ZymoBIOMICS Microbial Community Standards) for method validation and quality assurance. Our portfolio includes:

2.1 Standardised Sample Collection and Processing – Stool, Biopsy, and Swab
We provide validated sample collection kits for stool, biopsy, and mucosal swab samples, with clear instructions and stabilising buffers that preserve the nucleic acids and metabolites at room temperature for up to 7 days. We perform DNA and RNA extraction using optimised, bead‑beating protocols to ensure the lysis of both Gram‑positive and Gram‑negative bacteria, and we quantify the nucleic acid yield and purity using fluorometry and spectrophotometry. We also collect and stabilise stool aliquots for metabolomics (short‑chain fatty acids, bile acids, and other small molecules) using appropriate preservatives.

2.2 Shotgun Metagenomic Sequencing – Species‑Level and Strain‑Level Resolution
We perform high‑depth shotgun metagenomic sequencing (targeting > 10 million reads per sample) on Illumina NovaSeq platforms. Our bioinformatics pipeline includes: (a) taxonomic classification using MetaPhlAn 4 and Kraken2/Bracken, providing species‑level and, where possible, strain‑level identification; (b) functional gene profiling using HUMAnN 3, which quantifies the abundance of gene families and metabolic pathways (KEGG, UniRef, and MetaCyc); (c) pathway coverage and abundance calculations; and (d) resistome analysis for antimicrobial resistance genes (using CARD and ResFinder). We provide a comprehensive report that includes the species‑level taxonomic profile, the functional gene repertoire, and the metabolic pathway activity scores.

2.3 Metabolomics – Profiling of Short‑Chain Fatty Acids, Bile Acids, and Neurotransmitters
We perform targeted and untargeted metabolomics using LC‑MS/MS and GC‑MS on the same stool samples. We quantify the concentrations of short‑chain fatty acids (acetate, propionate, butyrate), branched‑chain fatty acids, bile acids (primary and secondary), tryptophan metabolites, and neurotransmitters (e.g., GABA, serotonin, dopamine). We provide the absolute concentrations (in µM or µM/g) and the relative abundance of the different metabolites, enabling the correlation of the functional profile with the actual metabolic output.

2.4 Metatranscriptomics – Active Gene Expression and Metabolic Activity
For a dynamic view of the gut microbiome’s activity, we perform metatranscriptomics (RNA‑seq) to measure the actively expressed genes and pathways. We deplete ribosomal RNA (using a Ribo‑Zero kit) and sequence the remaining mRNA. We quantify the expression of functional genes and provide a profile of the actively transcribed pathways, enabling the identification of the metabolic pathways that are genuinely active at the time of sampling.

2.5 Diversity and Ecological Analysis – Alpha, Beta, and Network Metrics
We perform a comprehensive ecological and statistical analysis of the microbiome data, including: (a) alpha diversity (Shannon, Simpson, Chao1, observed species, and Faith’s phylogenetic diversity); (b) beta diversity (Bray‑Curtis, Jaccard, and weighted/unweighted UniFrac) with ordination plots (PCA, PCoA, and NMDS); (c) differential abundance analysis (using DESeq2 and ANCOM‑BC) to identify the taxa or pathways that are significantly associated with different phenotypes; (d) co‑occurrence network analysis (using SPIEC‑EASI) to identify positive and negative interactions; and (e) machine‑learning models (random forest) for classification and biomarker discovery.

2.6 Host‑Microbe Correlation – Integrated Analysis with Phenotypic Data
We integrate the microbiome data with any available host‑related data (e.g., clinical metadata, dietary records, or host genotype) to identify correlations and potential causal links. We use Spearman correlation, canonical correlation analysis (CCA), and other multi‑omics integration tools to identify the microbial taxa and functions that are most strongly associated with specific phenotypes.

2.7 Personalised Report and Actionable Insights – Translation into Practice
We generate a comprehensive, personalised report that translates the complex data into clear, actionable insights. The report includes: (a) a visual summary of the gut microbiome composition and diversity; (b) a functional profile highlighting the metabolic pathways and the production of key metabolites; (c) a comparison to reference populations (e.g., healthy controls or specific disease cohorts); (d) recommendations for dietary modulation, probiotic or prebiotic supplementation, or lifestyle changes, based on the observed imbalances or functional deficits; and (e) a longitudinal comparison if multiple samples are collected over time.

3. Advanced Capabilities – Longitudinal Profiling, Strain Tracking, and Custom Panels

For clients requiring a deeper or more specialised characterisation, we offer a suite of customised, research‑grade services that go beyond standard gut microbiome testing:

3.1 Longitudinal and Time‑Series Monitoring – Tracking Community Dynamics
We perform longitudinal profiling by collecting and analysing samples from the same individual at multiple time points (e.g., before, during, and after an intervention). We use mixed‑effects models and trajectory analysis to identify the taxa and functions that change significantly over time, providing a dynamic view of the microbiome’s response to the intervention.

3.2 Strain‑Level Tracking – Strain Persistence and Engraftment
We use strain‑resolved metagenomic analysis (using StrainPhlAn or inStrain) to track the presence, persistence, and engraftment of specific probiotic or commensal strains over time. This is essential for evaluating the effectiveness of a probiotic intervention or for studying the colonisation dynamics of a specific strain.

3.3 Virome and Mycobiome Profiling – Complete Gut Ecosystem
We characterise the gut virome (Bacteriophages and eukaryotic viruses) and the gut mycobiome (fungi) using a combination of viral enrichment, specific primers, and shotgun sequencing. We provide a complete picture of the gut ecosystem, including the phage‑bacteria interactions and the fungal diversity.

3.4 Antibiotic Resistance Gene (ARG) Profiling – Resistome Characterisation
We provide a detailed resistome analysis by identifying all antimicrobial resistance genes (ARGs) present in the metagenome, their abundance, and their potential mobility (by identifying the plasmids or transposons carrying them). We provide a risk assessment of the resistance burden.

3.5 Gut‑Brain Axis and Neuroactive Metabolite Profiling
We perform a targeted analysis of the metabolites that are relevant to the gut‑brain axis, including neurotransmitters (GABA, serotonin, dopamine, glutamate), tryptophan metabolites, and short‑chain fatty acids. We provide a comprehensive report on the neuroactive potential of the gut microbiome.

3.6 Custom Report Design and Data Integration – For Clinical or Research Protocols
We can design custom reports to match your specific requirements (e.g., for a clinical trial, a specific disease cohort, or a research study). We can integrate the microbiome data with your existing data streams (e.g., clinical, biochemical, or dietary), and we provide the data in a format that is ready for publication or for submission to regulatory authorities.

4. Data Integrity, Standardisation, and Comprehensive Reporting

All analyses are conducted under a strict quality management system that includes the use of certified reference materials, routine controls (including extraction blanks and PCR blanks), and participation in proficiency testing schemes. Our reports provide:

• Full method description – detailing the sample collection, DNA/RNA extraction, library preparation, sequencing platform, and bioinformatics pipeline.
• Detailed results – including the taxonomic profile (with relative abundance at phylum, family, genus, and species levels), the functional gene profile, the metabolic pathway analysis, the metabolomics data, and the alpha/beta diversity metrics.
• Quality control data – the results of the concurrent controls (e.g., extraction blanks, PCR blanks, and positive controls), confirming the validity of the run.
• Graphical outputs – including taxonomic bar plots, diversity curves, ordination plots, heatmaps, network diagrams, and, where appropriate, personalised dashboards.
• Interpretative comments – by our senior clinical microbiologists and bioinformaticians, providing a clear, actionable summary of the findings, the implications for health or disease, and the specific recommendations for intervention.

Our reports are structured to meet the requirements of clinical research, regulatory submissions, and individual health consultations. All data are stored in a secure, auditable environment.

Turnaround times: 3‑4 weeks for standard shotgun metagenomic analysis, 4‑5 weeks for metagenomics combined with metabolomics, and 2‑3 weeks for 16S rRNA amplicon profiling. Expedited services are available for urgent clinical or research projects.
