Rapid Tests: How to Adopt Best Practice

Frontline professionals regularly face decisions based on drug and BBV test results—but those results are only as reliable as the conditions around them. Could you spot a false positive? Would you notice if the test kit was expired?

This is the final part of our 3-blog series (part 1 and part 2), spotlighting five more questions from our 15-question knowledge quiz, built to support real-world practitioners. Here’s what else is waiting inside the quiz:


11. Which drug are you least likely to see on a 6-panel urine cup test?

Most 6-panel tests cover common substances like THC, opiates, cocaine, amphetamines, benzodiazepines, and methamphetamines. But what about ketamine? It’s often excluded unless specifically requested.

12. Which factor can affect the accuracy of a urine drug test?

From expired kits to sample handling, temperature issues, and deliberate tampering—many factors can skew results. Are your team’s procedures tight enough?

13. How should a used rapid Blood-Borne Virus (BBV) test be disposed of?

Working in criminal justice or community services means you're handling clinical waste. Are your disposal practices compliant with safety and confidentiality standards?

14. Why is it important to check the expiry date on a test kit?

Out-of-date kits can produce false negatives or false positives, putting people at risk. In services where decisions can affect housing, medication, or liberty, that’s a big deal.

15. How long does cannabis remain detectable in urine cup or oral fluid testing?

This question gets into test windows: oral fluid detects recent use, while urine might show cannabis for days or even weeks, depending on frequency. Know the difference—it matters.
