Comprehensive Digestive Stool Analysis (CDSA) Level 4+

This snapshot brings together your key results, context, and next steps to give a clear picture of your health.

how your digestive system is functioning day to day: the appearance and consistency of your stool, its acidity, fat content, and whether blood is present. Together these flag poor fat absorption, inflammation or bleeding that warrants a closer look.

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 are what your gut bacteria make when they ferment dietary fibre. Butyrate is the one to watch — it's the primary fuel source for the cells lining your colon, and low levels are a common finding when the community is depleted. This stool test reports all four: butyrate, acetate, propionate and valerate. Most panels report three or none.

Five parasites, including Blastocystis hominis and Dientamoeba fragilis, both of which are commonly carried without symptoms.

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.

Lactobacilli and bifidobacteria in particular help inhibit gut pathogens, control pH and synthesise vitamins. Reported with quantities against the range expected in a healthy gut.

These bacteria are pathogenic and are those that have the potential to cause disease in the gut.

Organisms normally present in small quantities that can have adverse effects when overgrown. Beneficial bacteria protect against them colonising.

Candida and other yeasts are normal gut inhabitants, so quantity rather than presence is the finding. Overgrowth can follow antibiotics, antacids or steroids.
