For CIRS evaluation, ERMI or HERTSMI-2 testing is essential, not visual inspection.
Testing hierarchy for CIRS:
- ERMI Test - Gold standard, tests 36 species, $285-290
- HERTSMI-2 - Tests "Big 5" molds, $155, included with ERMI
- EMMA Test - Includes mycotoxins, $400+
- Air sampling - Supplementary only, misses history
ERMI uses DNA-based MSQPCR technology to quantify mold species and compare to national database. CIRS patients need ERMI below 2 or HERTSMI-2 below 11 for safety.
Q: ERMI vs. professional inspection - which is better?
A: Both serve different purposes for CIRS patients:
ERMI advantages:
- Quantifies specific species DNA
- Provides historical contamination picture
- Required for Shoemaker Protocol
- Objective numerical threshold
- Can be DIY collected
Professional inspection advantages:
- Identifies moisture sources
- Finds hidden mold growth
- Provides remediation scope
- Documents for insurance/legal
ERMI's limitation: composite sampling from multiple rooms makes source identification impossible. Best practice: ERMI for CIRS evaluation + professional inspection for remediation planning.
