Meth testing questions

A meth test samples surfaces in a property — walls, ceilings, door frames, exhaust fans and vents — for methamphetamine residue. Samples are read on site with a presumptive screen or sent to an accredited laboratory for a measured result in µg/100cm².

Queensland has no legislated figure of its own. The national 2011 guidelines say methylamphetamine on inside surfaces should not exceed 0.5 µg/100cm², and Queensland bodies such as the RTA refer to those guidelines.

Sampling time depends on the number of rooms and structures in the scope. Screen results are available on the day; laboratory turnaround is confirmed when the test is booked.

Usually whoever needs the answer: the buyer before settlement, the owner for a rental, or the insurer during a claim. Every test is quoted before it is booked.

Levels and their pattern give a strong indication. Manufacture usually leaves higher, more widespread readings; smoking usually shows lower readings concentrated in certain rooms. The report explains what the results suggest.

No. Meth Testing QLD only tests. Keeping testing separate from the works means the clearance result is independent of whoever did them.

No. Wipe and swab samples are taken from small marked areas using a template. Nothing is removed from the property.

Living areas, bedrooms, kitchen and bathroom exhaust points, return-air vents and any room where use is suspected. The 2011 guidelines say any room used by a child under 16 should be sampled at least once.

Yes. A tenant can raise suspected contamination with the owner or manager. The RTA describes a Form 11 notice to remedy breach if the request is ignored.

Yes. Unmarked vehicles, and the job is not discussed with neighbours or anyone the client has not authorised.

They are useful for a first look. For a purchase, an insurance claim, a tenancy dispute or a clearance, an independent tester’s documented report carries more weight.

Some policies do, often with conditions such as a baseline test or regular inspections. Check the policy wording; reports are written to support a claim.

No. The Environmental Health Australia code of practice uses 10 µg/100cm² for commercial and industrial settings and roof spaces, and 0.5 µg/100cm² for homes.
