The DNA analysis

HouseTest has developed a new analysis based on dust or air samples to determine whether a given building is mould infested.

Furthermore, the DNA analysis facilitates the detection of concealed moulds, as mould habitats differ according to species. This also limits the amount of construction work required on the building.

The DNA analysis involves collecting a dust or air sample from the building in question and sending it to our laboratory. The sample is then analysed for traces of mould DNA.

DNA molecules are part of all living organisms and can be used to detect moulds and determine the species, as each has a unique DNA sequence.

As dust will contain mould spores and fragments, DNA can be used to detect moulds and bacteria in dust samples.

Using HouseTest's DNA analysis, the type and quantity of mould can be detected from the dust sample. Depending on the species and quantity found in the sample, the overall state of health of the building is assessed, including signs of mould due to high relative humidity.

HouseTest was founded in 2011 by scientists from the University of Southern Denmark and Danish technological innovation organisation SDTI.

We have developed a new qPCR-based analysis to detect harmful mould and bacteria growths in buildings far quicker and more effectively than by conventional means.

HouseTest cooperates with Danish scientists employing the analysis in their indoor climate research projects.
