HERTSMI-2 Mold Test – Big 5 Mold Dust Analysis
The HERTSMI-2 Mold Test analyzes a dust sample to detect 5 specific molds known as the “Big 5”. These molds are commonly associated with water-damaged buildings, indoor moisture problems, and environments where mold growth may be present.
What does the HERTSMI-2 test analyze?
The HERTSMI-2 test focuses on the following 5 molds:
- Aspergillus penicillioides
- Aspergillus versicolor
- Chaetomium globosum
- Stachybotrys chartarum
- Wallemia sebi
What is it used for?
HERTSMI-2 can help evaluate whether these specific molds are present in the dust of a home, office, or other indoor space. It is a focused mold test because it analyzes only these 5 molds rather than a broader mold panel.
Ideal for:
- Homeowners who want to check for mold in an indoor environment.
- Properties with a history of moisture, leaks, flooding, or water damage.
- Customers looking for a focused test for the molds known as the “Big 5.”
- Environmental evaluations before or after mold cleaning or remediation.
- Indoor spaces where mold exposure is a concern.
Important Information
This test does not replace a professional inspection and is not a medical diagnosis. Results should be interpreted together with the property’s moisture history, visible conditions, reported concerns, and guidance from a qualified professional when needed.
