What it measures
Beneficial Bacteria Profile
Stool (PCR)
Measures Lactobacillus, Bifidobacterium, Akkermansia muciniphila, Faecalibacterium prausnitzii and other protective species. Low diversity is a key dysbiosis pattern.
Reference range: Adequate diversity preferred
Opportunistic Organisms
Stool (PCR)
Clostridium difficile, Enterococcus faecalis, Klebsiella, E. coli pathovars, Staphylococcus aureus. Overgrowth indicates dysbiosis.
Reference range: Low or absent preferred
Parasites
Stool (PCR)
Blastocystis hominis, Dientamoeba fragilis, Giardia, Cryptosporidium. Detection changes treatment approach significantly.
Reference range: Absent preferred
Yeast and Fungi
Stool (PCR)
Candida albicans, non albicans Candida species, Rhodotorula. Overgrowth often drives sugar cravings, brain fog and genital symptoms.
Reference range: Low or absent preferred
H. pylori
Stool (PCR)
The bacteria associated with gastric ulcers, reflux, B12 deficiency and elevated gastric cancer risk.
Reference range: Absent preferred
Calprotectin
Stool
Inflammatory marker that distinguishes inflammatory bowel disease patterns from functional disorders.
Reference range: Under 50 ug/g normal
Pancreatic Elastase
Stool
Measures exocrine pancreatic function. Low elastase indicates digestive enzyme insufficiency and drives malabsorption.
Reference range: Above 200 ug/g normal
Secretory IgA
Stool
Gut mucosal immunity. Both high (active immune response) and low (suppressed immunity) have clinical significance.
Reference range: Within range
Beta Glucuronidase
Stool
Enzyme that recycles oestrogen and toxins. Elevated activity can contribute to oestrogen dominance symptoms.
Reference range: Within range
