Key benefits of Ochratoxin A (OTA) testing
- Ochratoxin A exposure tracking from cereals, coffee, wine, and dried foods
- kidney-relevant mycotoxin monitoring
What is Ochratoxin A (OTA)?
Ochratoxin A is a mycotoxin produced by Aspergillus and Penicillium molds that contaminate improperly stored grains, coffee, wine, dried fruits, and spices. It is directly measurable in urine via LC-MS/MS.
Why is Ochratoxin A (OTA) important?
OTA is classified as a possible human carcinogen (IARC Group 2B) and is nephrotoxic (kidney-toxic) based on extensive animal data. It is one of the most frequently detected mycotoxins in human blood and urine samples globally, reflecting widespread low-level dietary exposure. Regular monitoring may be valuable for high-risk dietary patterns.
What insights will I get?
Your OTA level may reflect dietary exposure from coffee, wine, grain products, dried fruits, or spices contaminated with Ochratoxin A. Elevated levels may prompt review of grain storage quality, coffee sourcing, and wine consumption. Members with kidney health goals may find this marker particularly relevant.

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.
