Dust Testing Showdown: EnviroBiomics vs Liz Biotech vs Mycometrics (ERMI/HERTSMI-2 Experiment)
In this CIRS Group Podcast episode, Barbara describes a controlled dust-test experiment comparing MSQ PCR/ERMI results across three CIRS-relevant labs—EnviroBiomics, Liz Biotech, and Mycometrics—using dust collected the same day from the same home and surfaces, divided into left/middle/right sections to reduce sampling bias. The labs returned very different ERMI/HERTSMI-2 scores (Mycometrics 7.4/12, Liz Biotech 13.4/18, EnviroBiomics 18.8/20), while showing broadly similar mold “fingerprints,” suggesting major differences in reported concentrations rather than species detected. They emphasize the test does not prove which lab is correct, recommend using the same lab for pre/post remediation comparisons, and focusing more on individual species profiles than top-line scores. Because all tests detected Stachybotrys and Chaetomium, Barbara suggests repeated deep cleaning, room-by-room retesting with one lab, and involving a CIRS-literate IEP if results remain concerning, while also sharing pricing, feature differences, and a prior EnviroBiomics reporting/customer-service issue.
