Swiffer Sampling Cloths
These cloths are supplied sterile and are intended for sampling of dust from horizontal surfaces.
Using disposable gloves, wipe surfaces of interest, recording the location of sampling on the Chain of Custody form.
Analysis can proceed by Mould Specific Quantitative Polymerase Chain Reaction (MSqPCR) which can detect up to 36 moulds associated with water damaged buildings to species level.
A comparison can be made between a group of 26 water damage moulds and 10 common moulds. This ratio is reported as an Environmental Relative Mouldiness Index (ERMI).
