The experts say that fungal species identification is the key to an accurate mold exposure assessment. The American Conference of Governmental Industrial Hygienists included a whole chapter dedicated to mold exposure assessment in the 1999 publication “Bioaerosols: Assessment and Control.” However, many investigators do not follow these guidelines and continue to use technology that not only provides genus level accuracy, like a spore trap. It is now 2012 and new technologies are energizing the industry. Breakthroughs in the world of molecular biology provide industrial hygienists with access to rapid and accurate DNA detection technology. The biases of spore trap and culture based inertial impaction technologies are becoming non-issue when investigators elect to use advanced mTrap technology. The mTrap was developed to standardize fungal species identification by providing the resolution necessary to identify airborne mold exposure issues. Data interpretation is no longer fuzzy. The mTrap ensures that the investigator is equipped with the necessary confidence to compare outside to inside fungal species.
