Method: Shotgun metagenomic sequencing (CLIA 21D2062464); not cleared or approved by the FDA. Results reflect relative microbial abundance for wellness education purposes. Not intended to diagnose or treat disease and not a substitute for clinical consultation. Microbial associations are based on emerging scientific research and may change over time. Derived from laboratory results. This score or index is not an FDA-cleared test. It aids clinician-directed assessment and is not a stand-alone diagnosis.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Xylooligosaccharides testing
- XOS prebiotic fermentation capacity tracking
- plant hemicellulose fiber processing potential
What is Xylooligosaccharides?
This metric estimates your gut microbiome's capacity to ferment xylooligosaccharides (XOS) - prebiotic fibers derived from plant hemicellulose found in bamboo shoots, corn cobs, and sugarcane, and available as a prebiotic supplement. Estimated from xylanase-encoding genes by shotgun sequencing.
Why is Xylooligosaccharides important?
XOS selectively stimulate Bifidobacterium and Bacteroidetes species. XOS fermentation capacity reflects the presence of hemicellulose-degrading bacteria and may indicate how effectively your microbiome can process plant cell wall-derived fibers.
What insights will I get?
Your XOS fermentation capacity indicates how well your microbiome can utilize xylooligosaccharide substrates from dietary hemicellulose. It may inform decisions around plant food diversity and targeted XOS prebiotic supplementation.
