The Dect4mould Mould Test is simple to use, giving you accurate results in as little as 5 minutes. The tests identify mould species that the U.S. EPA considers to be health concerns for you and your family. The Detect4Mould Test kit contains two test cassettes for the identification of mould species linked with poor Indoor Air Quality aspergillus and Penicillium (Asp/Pen) and stachybotrys. This product is intended for use in the home and office for performing rapid screening of potential mould-containing samples.
Where to sample:
First, determine the area(s) that you will be sampling. Typically, this will be:
Settled dust on a flat surface (bookshelf, window sill, top of door frame, etc) in the room of concern, or in a central room. Areas of visible (suspected) mould growth due to water intrusion or other events. Samples from multiple areas, if you have only one test kit but wish to test multiple areas. Note: A “positive” result indicates one (or more) of the areas sampled as contaminated with mould and further testing may be necessary.
Collecting the sample:
Remove the Dect4mould swab from the package (it has a liquid bulb at it’s top)
Grasp the “Collection tube” with both hands and gently seperate the liquid-filled bulb end from the swab sleeve, exposing the white cotton swab tip. Rub the white cotton swab on the surface area until some of the material is visible on the cotton swab. In areas you see mould – do not over sample. If you can see visible material on the white cotton bud, you have a sufficient sample.
After collecting the sample, firmly insert the swab back into the swab tubes sleeve.
Bend the liquid-filled bulb at its base until you hear the blue extension snap, then bend it back in the other direction until it snaps again. Squeeze the bulb several times, releasing the rinse buffer onto the white cotton swab in the sleeve. Shake the “collection tube” for ten seconds.
You are now ready to run the cassette test.
Running the cassette test:
Open the foil pouches and place both the Asp/Pen and Stachybotrys test cassettes on a level surface. Twist off the white cap at the bottom of the “collection tube”. Slowly add five drops of the sample to both cassettes by gently squeezing the sides of the swab tube sleeve, placing the five drops into the round sample port of the cassette. Note that the drops are most easily dispensed by squeezing the collection tube sleeve – not the bulb part. Record the time when the sample was added, visually evaluate the test cassette after five minutes. Positive results may appear in just a few minutes, but also inspect the test cassette after 15-20 minutes have elapsed.
Interpretation of results:
Within minutes, one or two-coloured lines will appear on the test cassettes. At high concentrations of mould, positive results can be seen more quickly. DO NOT interpret results if more than 20 minutes have elapsed.
The cassette is negative when a single coloured line (C – control line) appears.
The test is positive if two coloured lines appear. ( c – control line and T – test line ) Note: Any visible line in the test window indicates a positive test.
What does a POSITIVE result mean?
Dect4mould screening tests are highly sensitive to specific mould types that are suspected to cause health issues. A positive result indicates that the area that was sampled contains detectable levels of these moulds. It does not necessary indicate that you have a serious mould issue but rather that you should consider consulting with a professional indoor air quality inspector or remediation service professional. The actions you take will depend on many factors including the extent of the mould infestation, the specific type of mould, the overall air quality in your living spaces and the costs involved. For serious mould issues, it is strongly recommended that you follow up with a laboratory test. These can be conducted through MedNZ Ltd.
What does a negative result mean?
Remember there is mould everywhere around you. The question is at what level and whether certain individuals may be sensitive to the types that are present. AlthoughDect4mould tests are highly sensitive screening devices for specific mould types, a NEGATIVE result indicates that the area sampled does not contain mould levels above a certain significant level. It also does not conclusively indicate that there may not be a mould issue elsewhere in your property. A negative result on a settled dust sample does give a general indication that there is not a significant mould spore level in the air within the areas tested. .
Limitations of the procedure:
Negative results may occur when levels of specific antigens (mould) are below the detectable concentration level (sensitivity) of the cassette test.
Dect4Mould is not intended for post-remediation clearance testing.
