Unfortunately, urine mycotoxin testing is not diagnostically significant.

"Even if we are presented with impeccable lab results from ELISA and thorough use of standard differential diagnosis (we aren’t), based on world-wide control data, and a robust literature on CIRS, there is no basis to ascribe any diagnostic significance to urine mycotoxin testing" https://www.survivingmold.com/Publications/Urinary_mycotoxin...

However, there are significant blood tests including Transforming Growth Factor Beta-1 and Complement C4-A. https://en.wikipedia.org/wiki/TGF_beta_1 https://en.wikipedia.org/wiki/C4A
