DFA use Mycometer analysis as a qualitative investigation tool when assessing the extent and severity of mould contamination within a property. Mycometer testing analyses both air and surfaces and was developed in Denmark following a rigorous data collection and testing methodology of indoor environments. Mycometer testing has been validated by the Environmental Protection Agency in the United States and is used globally to assess the levels of mould in the air or on surfaces.
Mycometer testing is based on identifying a specific enzyme that is present in mould, known as NAHA, which provides a ‘relative mouldiness’ level. The activity of this enzyme is measured using a fluorescent molecule that binds to the enzyme and releases fluorescence under ultraviolet light. The relative levels of light released are measured via a fluorometer. The fluorescence signal produced is proportional to the amount of mould present in the sample.
DF&A use Mycometer testing to:
- Understand the amount of mould present, both viable (living) or non-viable (dead)
- Provide an objective scoring method for understanding the ‘relative mouldiness’ of a property compared against an exhaustive research library
- Reveal whether there is any hidden mould within a property, such as in void spaces.
- Indicate whether further investigation using more targeted test methodologies such as DNA speciation are required
