4. ERMI Test
The Environmental Relative Moldiness Index (ERMI) was originally developed by the US Environmental protection Agency (EPA) and is based on dust samples collected throughout a home or building. Thirty Six (36) different fungi make up the ERMI test and are species specific. There are two types of mold groups:Group I (Water damaged homes) and Group II (commonly found in all homes). ERMI does not help identify the mold “Ground Zero” or what the water trigger is. And many times, ERMI does not give you all the answers you are looking for.
5. ARMI Test
The ARMI is an acronym for American Relative Moldiness Index. This test is a more cost efficient version of the ERMI testing but is not as thorough. This test correlates with the ERMI for predicting the moldiness of homes. 13 different fungi make up the ARMI and are designated a group 1 (water damaged homes)and group 2 (commonly found in all homes). The fungi identified in the ARMI tests are: Stachybotrys chartarum, Chaetomium globosum, Cladosporium sphaerospermum, Aspergillus versicolor, Eurotium (A.) amstalodami, Penicillium variabile, Aspergillus flavus, Aspergillus restrictus, Penicillium crustosum, Penicillium purpurogenum, Aspergillus fumigatus, Penicillium corylophilum,
6. MSQ / PCR
Mold Specific Quantitative (MSQ) Polymerase Chain Reaction (PCR) air testing. Is a fast DNA based analytical method for genus and species level identification and quantification.
7. Petri Dish test
Different molds like different food sources where agar plate cultivation via a Petri Dish is the best way to identify Genus and Species of a particular mold. But is time consuming often taking more than 2 weeks to get an answer where some molds don’t grow well on this medium (likeStachybotrys)
There are many sources available for quick, inexpensive, DIY mold tests. Some are more reliable than others where none offer interpretative services that are reliable. Stay away from these testing services as it ultimately is a waste of time and money.
Mold Test Cost
Genus level mold testing from a competent / experienced firm usually runs from $75 - $150 per sample (depending on type of test) where species level testing runs a bit more ($150 - $300 per sample). Be sure to ask your mold pro what the difference is where they should be able to explain it to you very easily.
Want the Truth?
If you have a health related issue involving mold or just want to get to the bottom of your mold issue once-and-for-all, you will benefit greatly from engaging an experienced and competent mold investigative firm that not only knows how to identify hidden sources of mold (Mold Assessment), but how to correct the problem (Mold Remediation).
