Organisms in the digestive tract, such as bacteria, parasites and viruses can be the underlying cause of many digestive conditions and illnesses. The GI-Microbial Assay Plus or GI-MAP test offers a comprehensive analysis using DNA/PCR techniques that can provide the markers most relevant for understanding the digestive environment and the effects on the human body paying particular attention to microbial balances.
What is being measured
A summary of what is being tested:
- Parasitic, Bacterial and Viral Pathogens
- Normal Bacterial Flora – including Bacteroides fragilis group, Bifodobacter, Enterococcus & Lactobacillus
- Dysbiotic Bacteria – including Morganella morganii, Pseudomonas spp & Streptococcos spp
- Autoimmune Triggers – including Proteus mirabilus, Proteus spp & Klebsiella pneumoniae
- Opportunistic Parasites – including Blastocystic Hominis, Dientamoeba Fragilis & Endolimax nana

A little more detail
Blastocystis hominis – tested using PCR – which check for the DNA of the parasite.
Blastocystia hominis is a parasite commonly found in the GI tract. Symptoms of infection include:
- Abdominal cramps
- Weight loss
Candida species are constituents of a normal healthy gut flora however if an overgrowth of the yeast (candidosis) occurs, gut permeability can increase leading to leaky gut syndrome. This can allow the yeast hyphae to penetrate the gut wall lining resulting in potential systemic infections.
Helicobacter pylori is commonly thought to be the bacteria responsible for causing stomach ulcers, gastritis and virtually all abdominal ulcers, apart from drug-induced forms. It survives the acidic environment of the stomach and infection can lead to pain and inflammation, which over time can significantly increase the risk of gastric cancer. There is also the h. pylori breath test available by following the link.
(Faecal) Zonulin is a protein modulator of intestinal tight junctions that is used to assess intestinal permeability (IP). Recent peer-reviewed literature highlights the role that intestinal permeability plays in a host of chronic GI and systemic conditions.

Before taking the test
You will need a break after you have finished any anti-microbial programmes before being able to complete this test otherwise you risk having false negative results. The length of the break depends on the medication.
Samples must arrive back at the lab within 3 days of collection and must arrive on a Monday, Wednesday or Friday. Please check there isn’t a bank holiday if the Monday falls on day 3.
15 working days
