Comprehensive parasite test using stool sample to detect various gut parasites and bacteria.
Gut health testing evaluates the function and integrity of your digestive system through specialized markers. Tests may measure intestinal permeability (zonulin), small intestinal bacterial overgrowth (SIBO breath testing), food intolerances, parasitic infections, or microbiome composition. The gut is increasingly recognized as central to overall health — influencing immune function, mental health, nutrient absorption, and systemic inflammation. Results guide targeted interventions including dietary modifications, antimicrobial protocols, probiotics, and gut-healing supplements. Many chronic health issues — from skin conditions to autoimmune disease — have roots in gut dysfunction.

Biomarkers Tested
12Variations may indicate abnormal gastrointestinal conditions.
Detects bleeding in the digestive tract, indicating potential disease.
Salmonella infection usually results from ingestion of the bacteria from contaminated food, water or hands.
Campylobacter infection (campylobacteriosis) is a bacterial infection which most commonly causes gastroenteritis.
Shigella infection (shigellosis) is a type of gastroenteritis caused by Shigella bacteria.
This infectious bacteria can cause gastroenteritis and symptoms beyond the gut.
Aeromonas are bacteria that can cause an acute diarrhoeal illness.
Symptoms of Giardia infection can occur with 3 to 25 days and may include diarrhoea, nausea, vomiting, pale greasy foul-smelling stools, stomach cramps, passing excess gas, bloating, weight loss and fatigue.
Cryptosporidium is a microscopic parasite that causes the diarrhoeal disease cryptosporidiosis.
The bacteria can be present in the gut for months or year and misdiagnosed as IBS.
Amoebiasis is a parasitic disease (also known as amoebic dysentery) caused by infection with Entamoeba histolytica.
Some research suggests that people with IBS may be more likely to have Blastocystis hominis organisms in their stool.
