Rigorous and Laboratory Tested
Many Meth-testing suppliers employ inadequately trained, inexperienced staff using basic in-field testing kits or hand-held devices. This is of course cheaper. And hand-held devices do give instant results.
The problem with both methods is they do not meet Government guidelines (NZS8510:2017). So, in a tenancy tribunal or other court case, they would not stand up to scrutiny. In-field kits, for example, have issues with external variabilities and sensitivity that can give false positives and false negatives. Yet this is the means of testing used by many suppliers in the field.
At Meth Forensics we follow a two-stage testing procedure:
Step 1: Field Composite Testing
We begin with field composite testing using a kit supplied by our lab partner Hills Laboratories, to establish whether meth is present or not. Applying our skills in forensic examination and fire investigation, target rooms are selected, testing a number of different areas in each room. This identifies if there is a problem by analysing all the swabs together and giving one result.
Samples are analysed at the laboratory, with a result and debrief usually available within three to four working days.
Step 2: Individual Room Testing
If meth is present, the next step is individual room testing (often where we are called in by estate agents or insurance companies) to find exactly where the problem lies. This involves testing and analysing each room separately.
This can save substantial sums, as even with reasonably high levels of contamination, we can usually advise on how to reduce it below Government guidelines, without removing walls.
As you can see, it’s an approach that is not only more accurate and more robust. It’s often the most cost effective.
