Real Time Labs has the mold test that can identify the tricothecenes, aflatoxins, and ochratoxin A (in urine) that are talked about in the above link. The test is very pricey - $750.

If you want to test your living environment, there something called an ERMI test.

Instead of taking the expensive test RTL test, I took something called the C4A test. It's cheaper at $125 and my BCBS insurance covered most of it. If your results are above the range, then further investigation into mold is warranted.
