The detection of drugs using urine is well established with the first version of the Australian Standard AS 4308 being released in 1995. The current version of this Standard (AS/NZS 4308:2008) includes the requirements for on-site testing of a urine sample. This is the Standard against which NATA (National Association of Testing Authorities) assesses a Collection Agency when that agency seeks accreditation for its operations.
Most drugs can be detected in urine for 1 – 3 days after use and cannabis metabolites can be detected for much longer (30 days or more) particularly with regular or heavy use.
ToxLogic Pty Ltd trading as JK ProCare Systems is NATA accredited for on-site testing urine testing. We use the ProScreen Cup, which is a validated testing device under AS/NZS 4308:2008. Any urine specimen which cannot be reported as Negative using the on-site testing device is sent to an accredited laboratory for further testing. Confirmed laboratory results are usually available within 48 hours.
Limitations of the ProScreen Cup urine testing device
This testing device is verified according to the requirements of AS/NZS 4308:2008, which means it reliably functions in accordance with the manufacturer’s specifications. The manufacturer has set the cut-off level for one of the amphetamine-type stimulants, MDMA (Ecstasy) at 1,200ug/L. The cut-off level for amphetamine-type stimulants in AS/NZS 4308:2008 is given as 300ug/L. It is likely that a urine level of MDMA under 1,200ug/L will not be detected by the ProScreen Cup and will be falsely reported as Negative.
We have been advised by the manufacturer that the ProScreen Cup is not readily able to detect recent use of temazepam. This is due to the structure of temazepam when it is eliminated from the human body. Some laboratories perform a pre-treatment of sample, which enhances the detection of temazepam.
