GI EcologiX™

Gastrointestinal Health & Microbiome Profile

A clinical tool born from a collaboration between Invivo Diagnostics Laboratory and global consultancy of leading clinicians and researchers in host-microbiome science.

By Invivo Diagnostics, our CQC-approved, B Corp-certified, UK microbiome laboratory.

GI EcologiX™: the ultimate in science, clinical utility, and integrity.

Our aim from the beginning was to elevate the science (methodology, technology, and biomarkers) found in gut microbiome tests, to that in the microbiology field.

We will never put profit above purpose. And our purpose is – and always has been – to provide you with clinical tools for best patient outcomes. We have an uncompromising adherence to the science, and a strong belief in what we are doing.

We asked ourselves: what makes a GI test clinically useful; what do we, as healthcare providers, really need to take away from a gut test result? In the GI EcologiX, we stripped away the unnecessaries – the ‘noise’ – added key health and microbial markers with robust science and links to common symptoms and conditions such as SIBO and intestinal health integrity.

Establishing a methodology that is the most accurate we currently know of in the microbiology field, and using the latest technology was absolutely critical for us in the development of the EcologiX™ profiles. For this, we established an incredibly knowledgeable and experienced Scientific Advisory Board to join the laboratory team, and dedicated time and money to create profiles that are the ultimate in science, clinical utility, and integrity.

The GI EcologiX™ profile uses quantitative real-time polymerase chain reaction (qPCR), using TaqMan technology, which offers superior sensitivity, specificity, and reproducibility. We also measure gastrointestinal health markers by a range of protein-based assays. The sample collection devices underwent extensive validation to ensure optimal DNA yields.
