Microbiome Testing
£250.00
Our microbiome test delivers a detailed examination of your gut's microbial community using advanced shotgun sequencing technology. The analysis measures over 30 critical biomarkers—including bacterial strains, viral populations, fungal species, and archaeal organisms—that collectively influence digestive wellness and systemic health. Each microbial domain contributes specific functions to your gut ecosystem, from nutrient processing to immune signalling. The comprehensive results reveal your microbiota's composition, diversity, and functional capacity, enabling you to understand how your unique microbial profile supports or compromises your wellbeing.
