The Complete Microbiome Mapping (GI Map) uses advanced PCR technology to provide a detailed analysis of your gut health. It identifies beneficial bacteria, pathogens, parasites, viruses, and markers of inflammation and digestive function, offering a complete picture of your microbiome. This comprehensive test helps uncover hidden imbalances and guides personalised treatment strategies to restore optimal gut health.
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 Complete Microbiome Mapping test gives you a detailed understanding of your gut health, helping you uncover hidden imbalances that may be affecting your digestion, energy, mood, and immune function. It analyses beneficial bacteria, harmful microbes, and key digestive markers to provide a clear picture of how your gut is working. With these insights, you can take targeted action — such as adjusting your diet, adding specific probiotics, supporting digestion with supplements, or addressing infections — to help repair your gut, rebalance your microbiome, and optimise your overall wellbeing and long-term health.
What's included
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.
Gut Functional Markers
Gut 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.
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.
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.
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.
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.
Parasites
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 parasites such as Blastocystis hominis and Dientamoeba fragilis.
Worms
PCR-based stool worm tests are particularly useful when other diagnostic methods, such as microscopic examination of stool samples, do not yield definitive results. They can provide a more precise identification of the specific worm species present, aiding in targeted treatment and management of the infection.
Potential Autoimmune Triggers
An imbalance in the gut microbiome (called ‘dysbiosis’) has been associated with autoimmune diseases, particularly, rheumatoid arthritis, type 1 diabetes, multiple sclerosis and autoimmune liver disease.
Fungi & Yeast
This test looks for evidence of candida or other yeast overgrowth. Whilst yeasts are a normal inhabitant of the gastrointestinal tract, they may become an opportunistic pathogen after disruption of the mucosal barrier, imbalance of the normal intestinal flora or impaired immunity. This can be caused by things like antibiotics, antacids and stress.
Bacterial Pathogens
This panel also looks for evidence of other bacteria which may be pathogenic in nature, such as C.Diff, Citrobacter and Klebsiella.
Helicobacter Pylori
Viral Pathogens
