The most advanced microbiome test available, species-level precision
Shotgun metagenomic sequencing analyzes all the DNA in your stool sample — not just bacteria, but fungi, viruses, archaea, and parasites — providing species-level identification and functional pathway analysis of your gut microbiome.
Unlike 16S rRNA sequencing (used by most consumer microbiome tests), shotgun sequencing identifies organisms to the species and strain level and reveals what your microbiome is actually doing: producing beneficial metabolites like butyrate, or synthesizing harmful compounds like LPS and ammonia.
Most microbiome tests give you a vague snapshot of bacterial genera. Shotgun sequencing reveals the complete ecosystem with precision: exactly which strains you have, what they're doing, and what they're producing. This data allows Gabriel to design hyper-personalized probiotic, prebiotic, and dietary interventions based on your unique microbiome profile — not generic gut health advice.
Collect a stool sample at home using the provided kit. Ship it in the prepaid envelope. The sample undergoes whole-genome sequencing — a complex process that takes 4–6 weeks. Results include detailed microbiome composition and functional pathway maps. Upload to Gabriel for precision microbiome optimization.
Conventional practitioners read these results through a disease-focused lens — looking for what's broken. Gabriel reads them through a holistic lens — looking for what's out of balance and how to restore it. We see optimal ranges, not just "normal" ranges. We connect findings across all your diagnostics to reveal patterns that siloed specialists miss.
GI-MAP uses targeted PCR to look for specific known pathogens. Microbiome sequencing (16S rRNA or shotgun metagenomics) sequences ALL the bacterial DNA in your sample, revealing the full diversity and composition of your gut microbiome, including species that targeted tests would miss.
You'll learn your microbial diversity (higher is generally better), ratios of beneficial vs potentially harmful bacteria, which metabolic pathways your microbiome supports (like butyrate production or bile acid metabolism), and how your gut composition compares to healthy populations.
Popular options include Viome (metatranscriptomics, measures what microbes are actually doing), Thorne/OneGevity, and BiomeSight. Each uses different sequencing methods with varying depth. Viome's approach of measuring microbial activity rather than just presence is particularly informative.
A baseline test followed by retesting 3-6 months after dietary or supplement interventions. Your microbiome can shift meaningfully in weeks, but sustainable changes take months to establish.
Consumer kits range from $100-400 depending on sequencing depth. Viome's full panel is around $200-300. Clinical-grade sequencing through a practitioner can cost $400-600 with detailed interpretation.
