Mold Identification Methodology
There are various methodologies utilized in mold identification. The most common is the “spore trap” whereby a prescribed amount of air is impacted onto a microscope slide. This slide is then observed under several magnifications where the various fungi are qualified (identified) and quantified (counted). The molds are identified as type and number per cubic meter of volume.
Other methodologies for mold identification are swabs and tape lifts. In this methodology a moistened swab or a piece of clear tape is applied to the suspected fungal colony.
All collected samples are submitted to a certified laboratory for mold identification. The laboratory prepares a report that identifies the types of mold and the spore counts or colony forming units.
Mold Identification to the genus level
When a homeowner or facility manager request mold identification, they will receive a report from Georgia Environmental Assessment identifying the mold to the genus level. There are over 100,000 different types of mold identified so far. Each genus has or may have many specific species with each having its own characteristic. Even if there is need for mold identification to the specie level, the genus has to be identified in order to target a specific specie.
Mold Identification to the Specie Level
This is a more costly methodology as it requires a collected sample to be “grown” in controlled laboratory conditions. It usually takes approximately 10 days of “growing” in order to identify a specific specie. The process is usually requested by a medical doctor so that a correct course of action may be developed to treat a specific allergenic issue.
