DNA Analysis

265,00

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.

Sampling

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

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.

Reporting

Upon receiving a sample, HouseTest will perform The DNA analysis on the same day and notify you with a report by email.

The report states whether the DNA analysis has revealed signs of a mould infestation, and if so, which species. In some cases, the combination of species detected can be used to determine the dampness level and material hosting the infestation, which facilitates subsequent mould detection and control. This is also stated in the report.

Frequently asked questions

How many samples are needed?

Because of high sensitivity and precision of the DNA-analysis one single sample will usually cover a one-storey house of up to 150 square metres, if the sample is collected in a central place in the building, and if there is a normal air flow in the building. In larger buildings one sample per 150 square metres is needed and at least one sample per storey.

Where should I collect the sample?

The sample should be collected centrally in the building, e.g. hallways or living rooms. If a specific area of the building is suspected to harbour mould growth, the samples can be collected in this area.

What should I do if a sample is taken incorrectly?

If you suspect a sample having been collected incorrectly, please contact us, and we will send you a new swab at no expense.

How long does the analysis take?

HouseTest will analyse the sample at our lab and provide a report by mail on the same day we receive your sample in our mail.

What should I do if the analysis finds mould in my home?

HouseTest can facilitate contact to skilled building surveyors, who can help you identify the problem, remove the mould and make sure that the mould does not reappear.

How can the DNA-analysis reveal concealed mould growth?

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.
