Buying a house?

This mold test can be very valuable!

Mold-Specific Quantitative Polymerase Chain Reaction (MSQPCR) is a fast and highly accurate DNA-based analytical method for identifying and quantifying molds. MSQPCR methods can determine the genus and species level of molds. It was developed by scientists at the United States Environmental Protection Agency (USEPA) to detect and quantify molds associated with indoor air quality problems.

Many methods for quantifying molds rely on visually counting mold spores, a time-consuming and laborious process. MSQPCR improves upon these methods because it detects molds based on unique DNA sequences.

MSQPCR methods look for a combination of molds from two groups. One group consists of molds species associated with water-damaged homes and buildings.

Group 1:

Stachybotrys chartarum

Chaetomium globosum

Cladosporium sphaerospermum

Aspergillus versicolor

Eurotium (A.) amstalodami

Penicillium variabile

Aspergillus flavus

Aspergillus restrictus

Penicillium crustosum

Aspergillus niger

Aspergillus sclerotiorum

Penicillium purpurogenum

Aspergillus fumigatus

Penicillium corylophilum

Aureobasidium pullulans

Aspergillus ochraceus

Penicillium brevicompactum

Paecilomyces variotii

Aspergillus sydowii

Penicillium spinulosum

Wallemia sebi

Aspergillus unguis

Scopulariopsis brevicaulis

Scopulariopsis chartarum

Aspergillus penicillioides

Trichoderma viride

The other group consists of mold species commonly found in all homes.

Group 2:

Acremonium strictum

Alternaria alternate

Aspergillus ustus

Cladosporium cladosporioides v1

Cladosporium cladosporioides v2

Cladosporium herbarum

Epicoccum nigrum

Mucor & Rhizopus group

Penicillium chrysogenum

Rhizopus stolonife

The results of the test are then compared to a national database to produce a “moldiness” index specific to the property tested.

So why can this mold test be so valuable when buying a house?

If there is suspected water damage when the seller declares there has been no moisture or water events, finding any mold species in Group 1 can prove there was water damage at some point in time.
