GI EcologiX™ is the ultimate gut health and microbiome stool test using qPCR & ELISA technology to provide a comprehensive analysis of the GI ecosystem and chronic disease-related microbial (bacteria, yeast, parasites) markers, which are backed by the clinical literature, alongside host health markers.​

It is a chronic disease-centric profile, replacing acute microbial markers and those routinely tested for in healthcare systems.

The science ensures you gain data that is personalised and consistent, enabling meaningful clinical output and the ability to confidently compare two sets of results from the same patient.​

Needing just three swabs from one sample, this is a simple and easy home testing kit.

– 7 x health markers to assess inflammation, immune function, digestion, gut barrier health, and occult blood
– 63 x microbial markers including markers related to IBD, mucin degradation and gut barrier impairment, SCFA production, SIBO, H. pylori, dysbiosis, inflammation

4 reviews for GI EcologiX

  1. Rachel Philpotts re:Nutrition FM Clinic verified healthcare provider verified buyer

    This is an excellent functional test, backed by science and supported by an expert team of clinicians. I wouldn’t choose any other GI / microbiome test.

  2. Nicola Warran Holistic Therapies verified healthcare provider verified buyer

    I’m a nutritional therapist (www.ibsresolve.com) and I regularly use the GI EcologiX with my clients. Invivo have been fantastic at teaching therapists how to interpret and analyse the tests for the best results when working with clients. Personally, using the GI EcologiX provides me with so much information regarding a client’s inflammatory markers, digestion markers, mucosa health and levels of dysbiosis, as well as other pathogens/parasites that may be present. This in turn helps me devise a successful treatment plan. I have also run this test on myself on 3 occasions which helps me target any gut health tweaks I need to make.

  3. Lucy Harris verified healthcare provider verified buyer

    I’m a nutritional therapist (https://lucylovesnutrition.com/) and the GI EcologiX is by far my favourite test to recommend to clients experiencing GI symptoms. The results provide so much valuable information, helping me really get to the root cause of their health concerns and allowing me to personalise and target their health plans even further. The support from the clinician team at invivo is also 5*.

    My absolute number one test, I’ve lost count how many times I’ve used it!
