Sample Limitations:  Dust by Swiffer cloth sampling – we require a minimum of 10 mg dust – if you can see plenty of dust on the Swiffer it will be fine.

 

1. Please avoid sampling surfaces that have been hot.

2. Avoid surfaces that have been exposed to biocides, e.g Chlorine containing chemicals

3. Please, don’t sample from surfaces where there is Drywall dust or clay-like powder present.

 

 

 

Actinomycetes

The most frequent bacteria species found on Water-Damaged Building are Actinobacteria (which includes Actinomyces and Mycobacteria) this is the kind of bacteria that produce biotoxins similar to mold mycotoxin.  As a whole, biotoxins from bacteria by weight and by mass are far more important than say, mycotoxins. ”  This test is based on Next Generation DNA sequencing, also known as 16S metagenomics.  The test is based on microbial I.D of all the bacteria in the sample.  The Actino test was developed by selecting the top 40 Actinobacteria species in the sample to create a score of actinobacteria in a situation of Building-Related Illness (BRI).

 

Species included in the score have been reported on multiple studies linking them with BRI.

 

    The score ranges from a value of 0 to 40 Actinobacteria species.

Score system:

15 or Less: Indicative of a Healthy Building.

16-20: Further investigation needed.

21-40 Suggestive of Building Related Illness.

 

HERTSMI-2 Testing

 

Overview

HERTSMI-2 is a mold test that analyses the dust sample provided for 5 molds. These moulds are known as the “Big 5”. HERTSMI-2 is an acronym for Health Effects Roster of Type-Specific Formers of Mycotoxins and Inflammagens – 2nd Version.

 

How does HERTSMI-2 Differ from ERMI Testing

HERTSMI-2 differs from ERMI Testing in a few ways;

HERTSMI-2 Testing looks at 5 molds, ERMI looks at 36 mold species.
The ERMI gives the result as an easy to understand the comparison to an established database of water damaged buildings and nonwater damaged buildings.
As HERTSMI-2 Analyses for 5 molds it is cheaper to do the analysis compared to 36 for the ERMI.

Which Mould Species are identified in HERTSMI-2

Aspergilus Penicilloides
Aspergillus Versicolor
Chaetomium Globosum
Stachybotrys Chartarum
Wallemia Sebi

 

How Can the HERTSMI-2 Score be used

A HERTSMI-2 score <10 is indicative that the building is safe for re-occupancy.
