ERMI · Mold qPCR Analysis
A reading of your home’s mold signature, interpreted.
A whole-house dust profile across 36 mold species.
This home returns an ERMI of 16.6 — the HIGH relative-moldiness band against the U.S. national survey.
Spore equivalents per mg of dust by mold-specific qPCR, each with its national quartile (Q1–Q4). Green Q4 bars mark the species pulling this home’s index upward.
| Species | SE / mg | Level | Q |
|---|---|---|---|
| Eurotium amstelodami | 5,254 | Q4 | |
| Penicillium brevicompactum | 1,254 | Q4 | |
| Penicillium corylophilum | 746 | Q4 | |
| Aspergillus niger | 190 | Q3 | |
| Aspergillus penicillioides | 133 | Q2 | |
| Stachybotrys chartarum | not detected | Q1 | |
| Aspergillus versicolor | not detected | Q1 |
The species driving this score — Eurotium and Penicillium — are most commonly associated with humidity and settled dust, not widespread water damage. Here is the plan we recommend.
These results suggest elevated humidity may be present. We recommend confirming indoor humidity holds below 50% and correcting any damp areas first — before any cleanup — so the profile doesn’t simply return.
A whole-home deep clean — surfaces, and behind furniture and appliances — paired with an HVAC clean and sanitize addresses the dust reservoir this profile points toward. These results do not indicate anything more aggressive.
Once the cleaning is done, a second dust test shows whether the index has moved back toward the normal range. We compare the two side by side.
A clear answer and a plan you can act on.
ERMI characterizes the building’s settled dust — a measure of the home, not its occupants. It samples non-viable organisms at an unknown timepoint and does not detect active growth. It does not diagnose conditions or predict health outcomes; for any health question, consult your physician.
FAQ
Usually the next step is a targeted clean or a closer look at the source. We spell out which, and when a professional is worth calling.
Often not. Many results end in a thorough clean and a re-test. When a remediation or repair is the right call, we say so.
Yes. Many people re-test after a fix, a move, or a season. Your earlier report makes the comparison easy.
