What does the Faecalibacterium prausnitzii test measure?

Q: What is the reference range for Faecalibacterium prausnitzii?

The standard reference range for Faecalibacterium prausnitzii is Expressed as a proportion of total sequencing reads (relative abundance), compared with the laboratory's adult reference distribution.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Faecalibacterium prausnitzii (F. prausnitzii) is a clinical biomarker used in microbiome-gut assessment. Faecalibacterium prausnitzii is one of the most abundant commensal species of the healthy adult colon and a major producer of butyrate through fibre fermentation. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Faecalibacterium prausnitzii?

Faecalibacterium prausnitzii is one of the most abundant commensal species of the healthy adult colon and a major producer of butyrate through fibre fermentation. Butyrate is a principal energy source for colonocytes and has been studied for roles in epithelial barrier maintenance and mucosal immune signalling. Its relative abundance is sensitive to dietary fibre intake and to colonic conditions such as oxygen tension and pH.

Why is Faecalibacterium prausnitzii measured?

Reduced relative abundance of F. prausnitzii has been reported in inflammatory bowel disease cohorts and other inflammatory states, which has made it a frequently cited marker of a butyrate-producing, 'anti-inflammatory' community. The association is consistent across studies but remains non-diagnostic at the individual level; a low proportion is a prompt for dietary and lifestyle discussion, not a disease label.
