What does the Lactobacillus species abundance test measure?

Q: Why is Lactobacillus species abundance measured?

Lactobacillus presence supports gut barrier function and pathogen resistance in early life. Low or absent Lactobacillus in the first weeks, especially in caesarean-delivered infants, is a marker of incomplete vertical transmission and is associated with increased risk of early dysbiosis.

Q: What is the reference range for Lactobacillus species abundance?

The standard reference range for Lactobacillus species abundance is Variable; present in vaginally delivered and breastfed infants; often <10% relative abundance.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Lactobacillus species abundance (Lactobacillus %) is a clinical biomarker used in microbiome-gut assessment. Lactobacillus species are early colonisers, particularly in vaginally delivered infants who acquire maternal vaginal lactobacilli during birth. It is measured in 1 laboratory test on BiomarkersLabs.com.

What is Lactobacillus species abundance?

Lactobacillus species are early colonisers, particularly in vaginally delivered infants who acquire maternal vaginal lactobacilli during birth. They produce lactic acid and bacteriocins that inhibit pathogens and modulate immune signalling. Abundance varies with delivery mode and feeding practice and typically declines relative to Bifidobacterium as the milk-fed microbiome matures.
