Mold Testing

Mycometrics Mold Testing

We recommend dust sample testing through Mycometrics Labs as the most accurate way of getting the “big picture” of a building’s mold counts.

There are two different test options that we recommend.

#1 : ERMI – Environmental Relative Moldiness Index

This test was originally developed by the US Environmental Protection Agency (EPA).

It involves the examination of the proteins in a dust sample from the building for the genetic presence of 36 different mold species.

The HERTSMI is the same basic genetic test as the ERMI, except that it checks for the presence of only five particularly dangerous species of mold: Aspergillus penicilloides, Aspergillus versicolor, Chaetomium globosum, Stachybotrys chartarum, and Wallemia sebi.

How to Order

Option #1:

To order a test kit from Mycometrics, go to https://www.mycometrics.com/products.html

Select which test kit you would like.  

We recommend the ERMI – AccuCloth Kit or the HERTSMI – AccuCloth Kit (see the difference between the two above).

Place your order and you will receive the kit with further instructions on performing the test.

Option #2: 

Perform your own test with a brand new Swiffer dust cloth and mail it to the company.

We have found this option to be helpful as we search for a place to live and haven’t always had the time to purchase a kit online in advance.

You will need to purchase:

Directions for Gathering a Sample:

  1. Remove the number of plastic bags you will be using for collected samples from the box.
  2. Open Swiffer cloth container.
  3. Put on a pair of gloves and remove Swiffer cloths from the package, placing each in a plastic bag and seal the bag.
  4. Now you have cloths for several tests, if you would like to perform more than one.
  5. You may want to change gloves and follow the directions from Mycometrics linked below.

Please note: These directions are from Mycometrics and for use with their AccuCloth.  Please see contact information at the bottom to contact them with any questions you may have.  We are providing the following forms as current at time of posting.  Please email the company to verify these forms are the most up-to-date.

Mycotoxin Testing

The late Dr. Thrasher recommended using RealTime Labs for testing of mycotoxins.  We have never performed these tests ourselves, as they are quite expensive to do in addition to mold testing.  However, we would like to share this resource with you in case you are interested in furthering your knowledge of the toxins in your environment and body.
