— Defined
What “toxic mold” can and cannot mean.
“Toxic mold” is an informal, non-clinical term, not an environmental or medical diagnosis. It is often used in discussions of molds that may produce mycotoxins under some conditions, including Stachybotrys chartarum, Aspergillus, Penicillium, Fusarium, and Chaetomium. Environmental sampling may characterize the material collected from specific locations, but it cannot determine toxicity, exposure, illness, or health risk.
We discuss methods suited to the environmental question: spore-trap air sampling for a time-specific airborne snapshot, surface sampling to characterize collected material, and DNA-based ERMI or HERTSMI-2 analysis of settled dust. No method detects every condition in a building or directs medical decisions. Laboratory analysis is performed by AIHA-LAP accredited partners.
— Protocols
Five testing methods.
Spore-trap air sampling
Indoor and exterior baseline cassettes processed for genus identification and per-cubic-meter spore count.
Surface characterization
Tape-lift or swab from accessible material, processed to characterize the sample. Results apply to the sampled material, not the whole building.
ERMI
Environmental Relative Moldiness Index — qPCR DNA analysis of settled dust across 36 mold species.
HERTSMI-2
A focused DNA dust panel that characterizes specified mold targets in the submitted dust sample; it is not a health assessment.
Mycotoxin analysis
Laboratory analysis of selected dust or tape-lift material may be available by scope. It characterizes the submitted sample and does not diagnose toxicity or illness.
Clearance documentation
Post-remediation inspection and sampling can document conditions against an agreed scope; it does not guarantee future conditions or reoccupancy decisions.
