What does the Yeast and Fungal Organisms test measure?

Yeast and Fungal Organisms (Yeast) is a clinical biomarker used in microbiome-gut assessment. Yeasts, particularly Candida albicans and non-albicans Candida species, may colonise the gastrointestinal tract transiently or persistently. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: None to trace; laboratory-specific thresholds for Candida species, Geotrichum, and other yeasts.
Units: Semi-quantitative (none/1+/2+/3+/4+), log₁₀ CFU/g
Measured In: 1 test
Category: —

Functional medicine optimalNone to trace; persistent heavy growth (3+ to 4+) in the presence of symptoms prompts antifungal sensitivity testing and therapeutic consideration.

What is Yeast and Fungal Organisms?

Yeasts, particularly Candida albicans and non-albicans Candida species, may colonise the gastrointestinal tract transiently or persistently. In healthy hosts they are kept in check by commensal bacteria and mucosal immunity. Antibiotic use, immunosuppression, and carbohydrate-rich diets can promote fungal overgrowth.

Why is Yeast and Fungal Organisms measured?

Moderate to heavy yeast growth, especially with symptoms of bloating, diarrhoea, or systemic 'yeast syndrome' complaints, may warrant antifungal therapy and dietary modification. Candida overgrowth is a recognised sequela of broad-spectrum antibiotic use and is implicated in some cases of irritable bowel syndrome.
