Mold testing involves two main methods: air sampling and surface sampling. Both types require analysis by a certified laboratory.
Air sampling is conducted indoors and outdoors using spore traps or canisters. This method is used when there are no visible signs of mold. The outdoor samples are used to create a control or baseline to determine the level of contamination, and then the control is compared to the indoor samples.
Surface sampling is completed when mold is visibly present.
