What Do Your Mold Lab Test Results Mean?

Interpreting lab test results for indoor mold is currently not standardized. Therefore, it would not be surprising if you give 10 different people same copy of lab test results for interpretation and you get 10 different opinions. However, if you tell the 10 people what you wanted to find out from those results and also […]

Airborne Fungal Spores: Non-viable and viable Air Sampling Methods

Which Sampling Method Should One Use for Airborne Fungal Spores? Concerns about health issues, especially allergic reactions from inhaling fungal spores, has made air sampling an important component of indoor mold investigation. Air can either be sampled onto some growth media for culture analysis (a.k.a viable or culturable samples) or on a sticky surface or […]

How To Interpret Laboratory Results for Airborne Fungal (Mould) Samples

Laboratory results for airborne mould and bacteria concentrations can be difficult to interpret for two major reasons. Maximum exposure limits have not been set Currently, there are no set maximum exposure limits (MELs) or threshold level values for airborne indoor mould and bacteria concentrations. Setting MELs would be difficult for reasons which include limitations in […]

Guidelines for Interpreting Numerical Data of Non-viable (Spore Traps) and Viable Airborne Mould Samples

In this article we discuss additional guidelines for interpreting numerical data for viable and non-viable airborne mould samples. The guidelines may be used to decide whether further investigations are required after initial investigations. However, numerical laboratory results cannot be used as the primary determinant of whether there is a mould problem but should always be […]
