This is our most comprehensive gut health screening panel which includes a Complete Microbiome Mapping, a Food Intolerance Check, the Intestinal Permeability (Leaky Gut) Check, and also a SIBO breath test.
The GI Map test goes beyond standard stool testing by using DNA-based PCR technology, allowing for highly sensitive and specific detection of gut microbes. It measures the levels of beneficial bacteria, opportunistic pathogens, parasites, viruses, and fungi, as well as key digestive and immune markers like calprotectin, secretory IgA, and beta-glucuronidase. This in-depth analysis provides insight into how well your gut is functioning, whether there are signs of inflammation, leaky gut, or microbial imbalances that could affect overall health.
The large intestine is packed with bacteria, whilst the small intestine typically contains very few bacteria. If the small intestine becomes overgrown with bacteria it can lead to malabsorption of key nutrients, causing symptoms such as nausea, vomiting, diarrhoea, bloating, fatigue, malabsorption of nutrients and weight loss. Small Intestinal Bacterial Overgrowth (SIBO) is also thought to be a possible factor in some cases of fibromyalgia and chronic fatigue syndrome.
A food intolerance response takes place in the gut, and it occurs when you are unable to properly breakdown the food. This could be due to enzyme deficiencies, sensitivity to food additives or reactions to naturally occurring chemicals in foods. Often people can eat small amounts of the food without causing problems.
The Food Intolerance Check assesses your response to 96 foods. Your blood is screened for IgG antibodies to these foods using the ELISA method.
This is a finger prick blood spot test that doesn't require a visit to a collection centre.
Note that The Australasian Society of Clinical Immunology and Allergy (ASCIA) does not recommend IgG food intolerance testing as a diagnostic tool for food-related symptoms. According to ASCIA, the presence of IgG antibodies to specific foods does not prove the existence of a clinical intolerance or sensitivity. Clinical evaluation, medical history, and elimination diets are the preferred methods for identifying food intolerances or sensitivities.
The lining of the intestine and gut microbiome make the gut highly selective in absorbing specific nutrients. When this gut lining is compromised, unwanted substances can cross the barrier and activate an immune response. The test works on the principle that small molecules are readily absorbed by the gut and excreted in the urine, whilst larger molecules are not. Under normal circumstances the ratio of large molecules to small molecules is low. Where ‘leaky gut’ is present, the larger molecules are found to penetrate the gut lining and are detected in the urine.
Note this test CANNOT BE PERFORMED IF YOU ARE A DIABETIC with a fasting urine glucose level over 6mmol/L.
This urine test assesses levels of a synthetic sugar and mannitol that can be used to monitor improvements or deterioration in intestinal permeability.
This urine test measures:
SIBO Lactulose Breath Test
The lactulose test is used to measure oro-caecal transit time (OCTT) - this is the time interval between ingestion of lactulose and rise in breath hydrogen. Prolonged OCTT has been associated with SIBO.
This lactulose breath test measures:
Faecal Macroscopy
Faecal macroscopy examines the physical appearance of the stool, including colour, form, mucus content, and hidden (occult) blood. These visible features offer valuable insights into digestion, gut lining integrity, and the presence of irritation or inflammation. Changes in stool appearance can often be early signs of underlying digestive issues.
This stool test measures:
Short Chain Fatty Acids
Short chain fatty acids (SCFAs) are important compounds produced by gut bacteria when they ferment fibre, helping to nourish the gut lining, regulate inflammation, and support immune function. Healthy SCFA levels are linked to better digestion, stronger gut barrier integrity, and reduced risk of chronic diseases like diabetes, obesity, and colorectal cancer.
This stool test measures:
Gastrointestinal Functional Markers
Gastrointestinal functional markers assess how well the gut is performing its key roles in digestion, absorption, and immune defence. They measure important indicators such as enzyme activity, inflammation levels, gut barrier function, and detoxification capacity. Together, these markers provide a clearer picture of overall digestive system health.
This stool test measures:
Microbial Diversity
Microbial diversity reflects the variety and richness of different bacterial species living in the gut. A diverse microbiome is associated with stronger immunity, better digestion, reduced inflammation, and improved resilience against disease. Supporting a wide range of beneficial microbes is key to long-term gut health.
This stool test measures:
Parasites
Parasites can disrupt digestion, nutrient absorption, and gut lining integrity, sometimes without obvious symptoms. Detecting parasitic infections early allows for prompt treatment to restore gut function and prevent further health complications. Regular screening is important, especially for those with chronic digestive or immune symptoms.
This stool test measures:
Worms
Intestinal worms can cause a range of digestive and immune issues, particularly if left undetected. Identifying and addressing worm infections helps restore proper nutrient absorption and gut balance. Screening for worms is an important step in protecting overall digestive health.
This stool test measures:
Opportunistic Bacteria
Opportunistic bacteria are strains that are normally harmless in small amounts but can cause problems if they overgrow. Elevated levels may contribute to digestive symptoms, inflammation, or disruptions in the gut microbiome balance. Monitoring these bacteria helps protect gut health and prevent chronic issues.
This stool test measures:
Potential Autoimmune Triggers
Some gut bacteria have been associated with triggering autoimmune responses when present in high levels. Identifying these microbes can offer early insights into autoimmune risk and guide personalised strategies to reduce inflammation and protect immune system balance. Keeping these bacteria in check is important for long-term health resilience.
This stool test measures:
Fungi & Yeast
Yeast and fungi naturally exist in small amounts within the gut but can cause health problems if they grow unchecked. Overgrowth may lead to digestive discomfort, skin issues, fatigue, and weakened immunity. Assessing fungal balance helps identify hidden drivers of gut symptoms and supports targeted recovery.
This stool test measures:
Bacterial Pathogens
Pathogenic bacteria are harmful microbes that can cause acute infections, inflammation, and disrupt the gut microbiome. Detecting these bacteria early helps prevent serious illness and supports faster recovery. Managing pathogenic infections is essential for maintaining a healthy and resilient digestive system.
This stool test measures:
Helicobacter Pylori
Helicobacter pylori is a common stomach bacterium associated with ulcers, digestive discomfort, and inflammation. Testing for H. pylori helps determine if treatment is needed to restore stomach health and prevent complications like gastritis or more serious conditions. Managing H. pylori can greatly improve overall digestive wellbeing.
This stool test measures:
Viral Pathogens
Certain viruses can infect the gastrointestinal tract and contribute to inflammation, digestive symptoms, and immune system strain. Identifying viral infections supports a clearer understanding of gut health and helps guide appropriate immune support strategies. Early detection can help minimise long-term effects on gut function.
This stool test measures:
Normal Bacterial Gut Flora
A healthy gut microbiome is rich in beneficial bacteria that aid digestion, produce important nutrients, and support immune function. Measuring the levels and balance of these bacteria helps assess the resilience and health of the gut ecosystem. Strong levels of beneficial flora are linked to better digestion, mood balance, and disease prevention.
This stool test measures:

This holistic picture provides actionable insights to help you improve your gut health.
There are medical explanations and labels for many gut problems, but the big exception is Irritable Bowel Syndrome (IBS). Since many gut disorders have similar symptoms to IBS, ruling out a more serious underlying gut disease is an important first step.
Some gut problems can be a consequence of an undetected gut infection. A significant number of IBS (irritable bowel syndrome) cases could actually be due to undiagnosed gut pathogens such as Blastocystis hominis and Dientamoeba fragilis.
