GI Comprehensive Testing Package & Plan
GI Comprehensive Testing Package - Rather than simply handing you results, we connect the dots between your symptoms, lifestyle and gut profile - so you understand what’s really going on and feel confident about what to do next.
This package is ideal if you’re looking for a more detailed and clinically comprehensive overview of your gut health, or if your symptoms have been ongoing and need deeper investigation, the GI Comprehensive includes additional markers such as zonulin (a marker associated with intestinal permeability) and a broader assessment of Clostridia species, offering greater insight where symptoms may be more persistent or complex.
It may be particularly helpful if you experience:
Longer-standing digestive symptoms
Bloating, intermittent IBS-type discomfort or food reactions
Skin concerns that may be linked to gut health
Joint or arthritic symptoms potentially associated with intestinal permeability
Unpredictable digestion that hasn’t fully resolved
What you get as a part of the package: Simple at home stool test, a symptom checker questionnaire, dietary analysis, professional results interpretation and a personalised plan all designed to help you understand what’s driving your symptoms and support you on your individual health journey.
More Information:
Using advanced qPCR analysis and 16s rRNA sequencing, this test reveals what’s really happening in your microbiome so you can stop guessing and start taking targeted action.
What this test measures
A wide-ranging panel of essential markers, including:
✔ Full microbiome profile: Detailed mapping of beneficial, neutral and potentially harmful bacteria.
✔ Yeasts and parasites: Detect unwanted organisms that may be contributing to symptoms.
✔ Malabsorption indicators: Understand how well your body breaks down and absorbs nutrients.
✔ Inflammation and gut barrier markers: Includes calprotectin, secretory IgA and zonulin — key for understanding inflammation, immune response and intestinal permeability.
What’s included in your GI Comprehensive package
Everything you need for accurate insight and personalised action:
✔ At-home stool collection kit: Easy, discreet and non-invasive.
✔ Prepaid return shipping: Send your sample straight to the lab at no extra cost.
✔ Advanced lab analysis: qPCR and 16s rRNA sequencing provide clinical-grade results.
✔ Symptom questionnaire: Helps us connect your symptoms with your test findings for more accurate interpretation.
✔ Diet analysis:We assess your dietary patterns to identify potential triggers or areas impacting your gut health.
