Dr. Spurgeon has written several books including “The Collection and Interpretation of Indoor Mold Samples – A comparison of methods”. In his book and this presentation Dr. Spurgeon discusses his concern that “none of the sampling methods, or data interpretation methods, we use in the mold industry have ever been validated”. The book goes into detail on the importance of sampling to answer specific questions and gives you examples of what questions to ask. Dr. Spurgeon states that “the selection of the sampling method and data interpretation method affects the ability of the IEP to correctly interpret the sample results and assess condition. One objective of this manual is to improve the investigator’s ability to compare the utility of sampling and data-interpretation methods based on objective criteria.”
