Environmental illness is real with measurable physiological effects. And it is treatable.

Unlike mold-caused asthma and allergies, "Toxic mold illness" and CIRS (Chronic Inflammatory Response Syndrome) are not real conditions, as described in a recent Australian report:

"Toxic mold illness" is a popular scam among the grifters who market themselves as integrative/functional/naturopathic: https://www.thedailybeast.com/why-is-the-internet-so-obsesse...
The CDC warned against urine testing promoted by the "toxic mold" scammers: https://www.cdc.gov/mmwr/preview/mmwrhtml/mm6406a7.htm

I have been treated by Dr Shoemaker and am currently being treated by Dr Scott McMahon who is an expert researcher in the field. Call him and set up a consultation. There is a fair amount of blood tests but your symptom history and VCS tests will go a long way toward diagnosis.
YMMV, but after initial treatment I felt 40% better in 6 months. Ensuring a clean environment is critical. It took 5+ years of treatment to reach the 90% improvement.
However, each person is unique. Younger and less genetically susceptible patients improve much quicker.

There are two tests we do periodically: https://realtimelab.com https://mosaicdx.com/test/mycotox-profile/
You may be able to find ways to get the tests directly (not through a health practitioner) if that ends up being the path you need. They are not cheap and not typically covered by insurance, but we found being mysteriously ill was way more expensive in the long run than paying for tests. May your path to healing be a straight one!
"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
This area is definitely more "gray" than implied by your comment. I have tremendous respect for Shoemaker, but there are some gaps in that paper that did not appear to address how our practitioner used those tests for us. Many of the studies mentioned in the meta-review focus on the presence or absence of mycotoxins not the measured amount. Also, our practitioner used the test "backwards" compared to procedure outlines in the review paper. Our practitioner used the test before we had any evidence that we lived in a water-damaged building, whereas the paper is specifically focused on determining cause of illness after exposure to a water-damaged building.
