Key benefits of Verrucarin A (VRA) testing
- Macrocyclic trichothecene exposure tracking
- water-damaged building mold assessment
What is Verrucarin A (VRA)?
Verrucarin A is a macrocyclic trichothecene mycotoxin produced by Stachybotrys species and related molds associated with water-damaged buildings and some food substrates. Detected in urine via LC-MS/MS.
Why is Verrucarin A (VRA) important?
Like Roridin E, Verrucarin A is primarily a marker of water-damaged indoor mold exposure. Detection alongside other trichothecenes provides stronger evidence of Stachybotrys exposure than any single marker alone.
What insights will I get?
Your Verrucarin A level may indicate exposure to water-damaged building mold. Detection alongside Roridin E may strengthen the case for mold inspection of your home or workplace environments.

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.
