A new saliva testing standard has been released: AS/NZS 4760:2019, Procedure for specimen collection and the detection and quantification of drugs in oral fluid.
It’s available for purchase at Standards New Zealand right now.
There’s always been an Australian standard for saliva testing, but for the first time, New Zealand has one as well!
When can I start saliva testing to the standard?
Not for a few months at least, because the release of the standard has kicked a few other things into gear.
NZQA will develop unit standards for saliva collection and testing - there’s currently no timeline on this. After that, trainers will create training courses to those unit standards, get the courses approved, them begin publicly offering them. You’ll then be able to be trained to do saliva testing to the standard.
Manufacturers will develop saliva testing devices that meet the cut-off levels, and get these certified to Appendix C of the standard.
Laboratories also need to get set up and accredited for confirmatory saliva testing.
What are the new cut-off levels?
The cut-off levels for saliva screening are:
Amphetamines: 50 ng/mL
Cannabinoids: 15 ng/mL
Cocaine: 50 ng/mL
Opiates: 50 ng/mL
Oxycodone has been added and benzodiazepines have been removed, when compared to the urine standard.
It’s worth noting that the saliva standard measures in nanograms per millilitre (ng/mL), whereas the urine standard tests in milligrams per lite (μg/L), so the cut-off levels between urine and saliva aren’t directly comparable.
Where can I find out more?
Either purchase the standard and have a read through it, or keep an eye out for more updates from us.
