CIRS / ERMI / HERTSMI-2 Testing
across LA.
ERMI (Environmental Relative Moldiness Index) and HERTSMI-2 (Health Effects Roster of Type-Specific Formers of Mycotoxins and Inflammagens) are DNA-based dust-testing methods. Mold X helps clients collect and document these environmental samples according to laboratory instructions, with clear chain-of-custody records and plain-language reporting of the laboratory output. These tests do not diagnose CIRS or any medical condition; medical interpretation belongs with a qualified clinician.
