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 Zearalenone (ZEA) testing
- Zearalenone estrogenic mycotoxin exposure tracking
- grain contamination and hormonal pathway monitoring
What is Zearalenone (ZEA)?
Zearalenone is an estrogenic mycotoxin produced by Fusarium molds on corn, wheat, barley, and other grains, particularly following wet or cold pre-harvest conditions. Directly measurable in urine via LC-MS/MS.
Why is Zearalenone (ZEA) important?
ZEA can bind to estrogen receptors and has estrogenic activity in animal models. It is one of the most common mycotoxins in global grain supplies. Regular monitoring may be particularly relevant for members with hormonal health goals or those consuming high amounts of grain products.
What insights will I get?
Your ZEA level may reflect dietary exposure from contaminated corn, wheat, or other grain products. Elevated levels may prompt review of grain sourcing quality and storage conditions. Members interested in tracking dietary estrogenic mycotoxin exposure may find this marker particularly relevant to monitor.
