ERMI & HERTSMI-2 Dust Testing
DNA-based settled-dust testing — the screening method most CIRS-literate physicians reference — with collection protocols that make the results valid and interpretation that treats the score as an instrument reading, not a verdict.
What's included
- Collection planning: composite versus room-specific sampling matched to the question
- Proper collection sites: undisturbed dust reservoirs, not floors or fresh surfaces
- Accredited-lab qPCR analysis of water-damage and outdoor marker species
- Species-level interpretation against building findings, not just the composite score
- Baseline documentation for valid post-remediation comparison
Why it matters
Settled dust integrates weeks of exposure — a far better match for chronic-exposure questions than one air snapshot.
Species-level results point investigations: humidity organisms tell a different story than long-saturation markers.
A valid baseline is what makes your post-remediation retest mean something.
- A single hallway air cassette sold as a building screen
- Scores interpreted without any building context
- No documentation of collection sites and method
A defensible answer to 'is this building a problem' with species-level detail that directs the inspection — and a baseline your final clearance will be measured against.
