Urine Drug Testing products should be analysed by an fully accredited NATA (National Association of Testing Authorities) Laboratory. The Compliance Certificate advises the device, "was tested in accordance with Appendix B - Verification of performance of on-site devices around cut off of Australian and New Zealand Standard AS/NZ 4308: 2008."
Confirming the product is made to meet the Cut Off levels specified in the Australian Standard. What does this mean? The Cut Off levels are very important. The AS nominates six substances, including Opiates, THC (marijuana) Benzodiazepines, Cocaine, Methamphetamine and Methamphetamine. Where a donor, generally, an employee produces a urine sample and any one or more of these levels are reached or exceeded, producing a Non Negative or Requires more Testing, it is considered the donor should be removed, "stood down" or moved sideways from the workplace, pending Confirmatory Testing results, using a Laboratory and GC/MS results. Onsite results are referred as providing a Qualitative result or presumptive result. The result is generally referred as being "Negative" or no drugs found, "Non Negative" or "Requires further testing" drug found and not referred to as a "Positive" result.
There should be no intention to apportion blame or Best synthetic urine brands accuse the donor at this stage of the testing process. Onsite results being provided by the device in around 2.5 minutes generally. The urine sample should then be forwarded to a Confirmatory Testing Laboratory, where a sophisticated scientific instrument is used to provide an accurate GC/MS "Quantitative" result. This result indicates the exact reading of nanagrams per mililitre of the specific substance in the Urine. Provided the level exceeds the specified levels the result may then be considered a positive result. This result and this result only should be the basis of any action taken concerning the donor. All actions should be in line with the organisations laid down procedure as disclosed in their workplace Alcohol and other Drugs Policy.
