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 Richness index testing
- Antibiotic resistance gene diversity tracking
- number of distinct resistance gene families detected
What is Richness index?
The Richness index is a derived metric counting the number of distinct antibiotic resistance gene families (unique ARG types) detected in your gut microbiome by shotgun sequencing. It reflects resistance diversity rather than overall abundance.
Why is Richness index important?
A higher number of distinct resistance gene families may indicate broader historical antibiotic exposure or diverse dietary sources of resistance genes. The Richness index complements the Abundance index - one may be elevated while the other is not, revealing different patterns of resistance burden.
What insights will I get?
Your Richness index may indicate the breadth of antibiotic resistance gene types present in your gut. Together with the Abundance index, it provides a more complete picture of your gut microbiome's antibiotic resistance profile than either metric alone.
