Key benefits of Chaetoglobosin A (CHA) testing
- Chaetomium fungal mold exposure tracking
- water-damaged building assessment
What is Chaetoglobosin A (CHA)?
Chaetoglobosin A is a cytotoxic mycotoxin produced by Chaetomium species - molds frequently found in water-damaged buildings, soil, and some food substrates. Detected in urine via LC-MS/MS.
Why is Chaetoglobosin A (CHA) important?
Chaetomium is an increasingly recognized indoor mold associated with water damage, often found alongside Stachybotrys. CHA in urine may indicate exposure to Chaetomium-contaminated environments or food. This marker complements other building mold mycotoxins for a more complete indoor mold exposure picture.
What insights will I get?
Your CHA level may indicate exposure to Chaetomium mold from water-damaged environments or contaminated food. If detectable, assess potential water damage sources in your living or working 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.
