Method: LC-MS/MS (Liquid Chromatography/Tandem Mass Spectrometry) measuring free (unconjugated) mycotoxins in urine (CLIA 17D0919496); not cleared or approved by the FDA. Results in ng/g creatinine. Not a stand-alone diagnosis; should be interpreted in clinical context.
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 Roridin E (ROE) testing
- Trichothecene mycotoxin exposure tracking
- water-damaged building and mold exposure assessment
What is Roridin E (ROE)?
Roridin E is a macrocyclic trichothecene mycotoxin produced primarily by Stachybotrys chartarum (black mold) and related species. It is detected in urine via LC-MS/MS and reflects exposure to water-damaged building mold or contaminated food.
Why is Roridin E (ROE) important?
Macrocyclic trichothecenes from Stachybotrys are associated with water-damaged buildings. Urinary Roridin E may indicate exposure to indoor mold from water damage. Members interested in indoor mold exposure assessment may find this marker relevant.
What insights will I get?
Your Roridin E level may indicate exposure to Stachybotrys mold from water-damaged buildings or food contamination. If detectable, inspect your living and working environments for water damage and mold growth.
