Decoding Drug Test Panels: What Do MET, THC, and K2 Mean?

Decoding Drug Test Panels: What Do MET, THC, and K2 Mean?

If you are managing a WHS program or testing at home, the codes on a testing device can look like a chemistry exam.

To ensure your site is compliant with Australian Standard AS/NZS 4760:2019, it is vital to understand exactly what substances are being screened. Below is the breakdown of the standard substance abbreviations used on our 9-Panel SalivaTracer™, tailored for Australian workplace risks.

The Standard Panels (The "Big 7")

These 7 panels cover the most common illicit and prescription risks found in Australian industries (Mining, Construction, Transport).

  • MET (Methamphetamine)

    • Common Terms: Ice, Crystal, Shard.

    • Screening Focus: Highly potent stimulants. This is currently the highest-risk substance in Australian heavy industry due to its impact on aggression and risk-taking.

  • THC (Cannabis)

    • Common Terms: Marijuana, Pot, Weed.

    • Screening Focus: Cognitive impairment and slowed reaction times. Unlike urine tests (history), saliva targets recent use (fitness for work).

  • COC (Cocaine)

    • Common Terms: Coke, Blow.

    • Screening Focus: Short-term stimulants that cause erratic behavior followed by severe fatigue ("the crash").

  • OPI (Opiates)

    • Common Terms: Heroin, Smack, Codeine, Morphine.

    • Screening Focus: Central nervous system depressants that slow reaction times.

  • AMP (Amphetamines)

    • Common Terms: Speed, Goey.

    • Screening Focus: Stimulants similar to Meth but chemically distinct.

  • BZO (Benzodiazepines)

    • Common Terms: Benzos, Valium, Xanax.

    • Screening Focus: Prescription sedatives. A major concern for "fit for work" assessments as they mimic the effects of alcohol (drowsiness/coordination loss).

  • OXY (Oxycodone)

    • Common Terms: Endone, OxyContin.

    • Screening Focus: Semi-synthetic opioids. These are often not detected by standard OPI panels, requiring this specific strip for accurate screening.

The "Plus 2" (Why choose a 9-Panel?)

Our upgraded 9-Panel kits include two extra strips to target "synthetic" and "party" drugs that standard kits miss.

  • MDMA (Ecstasy)

    • Common Terms: E, Pills, Caps.

    • Screening Focus: While often cross-reactive with MET, a dedicated MDMA line ensures specific detection of this psychoactive substance.

  • K2 (Synthetic Cannabis)

    • Common Terms: K2, Spice, Chronic.

    • Screening Focus: Synthetic compounds sprayed onto plant matter. These are dangerous because they are often invisible to standard THC strips. Screening for K2 is essential for zero-tolerance sites.
