The GI360 Complete is an advanced comprehensive stool test designed to assess gut microbiome balance, digestive function, intestinal inflammation, immune activity and the presence of pathogens.
It combines multiple laboratory methodologies to deliver one of the most detailed overviews of gastrointestinal health currently available from a single at-home stool sample.
This test evaluates 253 biomarkers, providing deep insight into how well your gut is digesting food, absorbing nutrients, defending against pathogens and maintaining immune balance.
Why this test is useful
The gut plays a central role in digestion, immunity, inflammation, metabolic health and even mood and cognition. Subtle imbalances in the microbiome or digestive processes may contribute to chronic or unexplained symptoms long before they are detected on routine tests.
The GI360 Complete is commonly used to investigate:
chronic digestive symptoms
unexplained inflammation
suspected infections or parasites
immune dysregulation
food sensitivities and malabsorption
autoimmune and inflammatory conditions
By combining molecular testing, culture, microscopy and biochemical analysis, this test provides both broad screening and clinically actionable detail.
How the test works
You collect a stool sample at home using the materials provided
The sample is returned to the laboratory for analysis
Multiple advanced testing methodologies are applied to the same sample
Results are presented with clear reference ranges and interpretive markers
What is measured
This test assesses gastrointestinal health across several key domains:
gut microbiome composition and balance
pathogenic bacteria, parasites and yeast
digestive enzyme output and nutrient absorption
intestinal inflammation and immune activation
gut barrier integrity and mucosal immunity
microbial metabolic activity
Biomarkers tested
The GI360 Complete includes assessment of the following categories and markers (not exhaustive):

Laboratory methodology
A comprehensive, multi-layered analytical approach is used:
Multiplex PCR for simultaneous detection of commensal organisms and pathogens
Gold-standard microscopy for parasites, yeast, cells and fibres
Culture techniques for bacterial identification
Macroscopic stool assessment (colour, consistency, mucus)
BÜHLMANN fCAL® and fPELA® assays for calprotectin and elastase
ELISA for lactoferrin, lysozyme and secretory IgA
Gas chromatography for short-chain fatty acids
Colorimetric testing for carbohydrates
Guaiac testing for occult blood
Who should consider this test
This test may be useful if you:
experience chronic bloating, diarrhoea, constipation or abdominal pain
have suspected gut infections, parasites or yeast overgrowth
have inflammatory or autoimmune conditions
experience food sensitivities or malabsorption
want a deep assessment of gut microbiome balance
are addressing unexplained fatigue, brain fog or systemic inflammation
Understanding your results
Results highlight patterns of microbial imbalance, inflammation, immune activation, digestive insufficiency or pathogenic exposure.
Findings should always be interpreted in the context of symptoms, medical history, diet and lifestyle. Follow-up with a qualified healthcare professional may be appropriate to guide targeted interventions.
Returning samples to the lab
It is the user’s responsibility to organise sample returns.
Full instructions are included in the collection kit, which contains a pre-paid return envelope.
Results timeframe
Laboratory processing time is 6–8 business days, excluding transit time.
Timeframe begins once the laboratory receives your sample.
Important limitations
This test provides functional and clinical insight but does not diagnose medical conditions
Results may be influenced by diet, medications, supplements and recent illness
Abnormal findings should not be acted upon without appropriate professional guidance
