How Do Hygienists Check for Mold?
Sampling Techniques Professionals Use
Hiring an environmental hygienist to perform a mold test is the most accurate method for determining whether mold is growing in a residence. Learn about the sampling techniques professionals use and how test results can increase the effectiveness of mold cleaning.
An environmental hygienist will take samples to send to a lab for analysis. Depending on the situation, a hygienist may obtain different types of samples:
- Bulk (contents or materials)
Any of these methods can yield conclusive results about the type of mold present in a house. Air testing may include analysis of microbial volatile organic compounds and spores. Bulk testing may focus primarily on the presence of spores. All of these methods allow for targeted mold remediation measures.
There are several methods of lab analysis that a hygienist or mold specialist may recommend. The amount of detail and speed of these methods vary:
- A combination of these methods
Microscopy involves visual analysis and can provide results in as little as two days. Culturing is a slower process that involves growing mold spores in a Petri dish. This process can provide more detailed results, such as the subspecies of mold, but is slower and more expensive.
A hygienist can provide test results and recommendations for mold cleaning. A homeowner may want to work with a full-service restoration company to ensure that mold remediation proceeds as efficiently as possible. Depending on the species of mold and the extent of an infestation, different cleaning or quarantining methods may be recommended.
These are the three major stages of checking for mold. An environmental hygienist can recommend the best mold cleaning methods for a particular species of fungi or type of infestation. If a homeowner is concerned about mold damage at a residence in Reston/Herndon he or she should hire a certified hygienist.
