A certified mold inspector, trained in appropriate sampling methodology will perform the necessary testing. There are two types of mold tests, air quality testing and surface swabbing. Air quality testing is used to determine the type of mold and amount of airborne contamination. It is often used in conjunction with sample swabs. Air quality testing is often used when building inhabitants are suffering from health problems which may be association with fungal exposure, but when no obvious evidence of mold growth is present. First a sample of the outdoor air is collected – since mold spores are everywhere, the outdoor sample acts as a control to measure the indoor samples against. If the indoor air samples which are taken at several different location throughout the building report higher levels of mold, or types of mold that aren’t present in the outdoor samples then a mold problem may exist.
Surface swabbing occurs when visual mold is present. Samples are collected from visibly moldy surface by scraping or cutting the material with a clean tool. Or by wiping the area with a sterile swab or stripping the suspected area with clear tap. The samples are places in sterile plastic bags which are sent for testing. The surface samples are used to identify the specific mold types present.
All mold testing, analysis and reporting is done by an independent third party lab.
