Drug Testing

Methamphetamine (Meth, P) and precursor drug Contamination Testing

Hill Laboratories have the capability to test for traces of Methamphetamine from suspected contaminated dwellings. The test is carried out on wipe samples according to NIOSH method 9111, and is IANZ accredited.

This includes testing for three precursor drugs; Ephedrine, Pseudoephedrine and Amphetamine. Swab samples from the dwelling are taken and sent to the laboratory where they are extracted and analysed using LCMSMS (Liquid Chromatography with Tandem Mass Spectrometry Detection).  Results for methamphetamine greater than 0.5μg/100sqcm exceed the current New Zealand guideline levels.
