What does the Proteobacteria (phylum) — dysbiosis signal test measure?

Q: What is the reference range for Proteobacteria (phylum) — dysbiosis signal?

The standard reference range for Proteobacteria (phylum) — dysbiosis signal is Relative abundance at phylum level; typically a minor fraction of the adult gut community, with higher proportions flagged as a potential instability signal.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Proteobacteria (phylum) — dysbiosis signal (Proteobacteria) is a clinical biomarker used in microbiome-gut assessment. Proteobacteria is a phylum that includes many facultative anaerobes and several enteric organisms. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Proteobacteria (phylum) — dysbiosis signal?

Proteobacteria is a phylum that includes many facultative anaerobes and several enteric organisms. In a balanced adult colon it usually represents a small minority of reads. Expansion of this phylum has been proposed as a non-specific ecological marker of a perturbed or inflamed gut environment, for example where mucosal oxygen availability favours facultative anaerobes.

Why is Proteobacteria (phylum) — dysbiosis signal measured?

A sustained bloom of Proteobacteria is described in the literature as a candidate signature of microbial instability rather than a diagnosis in its own right. It is non-specific and can reflect recent illness, antibiotics, or dietary shifts, so an elevated proportion warrants context and repeat assessment rather than treatment of the number.

Reference ranges
