Supposedly they identify 92% of people that have a problem with biotoxins.

I passed my VCS, but I still benefit greatly from extreme mold avoidance. I only tried this because I have one of the mold susceptible haplotypes.

Yes it's the visual contrast test. Not sure about blood tests but shoemakers site talks about some markers he follows I think.
