Learn MorePoint of Care Testing Results: Can You Tell What’s Real?
In environments like mental health units, probation settings, or substance recovery services, a single test result can influence major decisions—from medication plans to safeguarding actions. But not every result is straightforward.
Our new 15-question quiz is built for frontline professionals who use rapid drug and BBV tests in complex real-life situations. Below are 5 of the questions you’ll encounter—designed to help you think critically and spot red flags.
Following questions 1 to 5 in this blog, here are five month teasers.
6. What could trigger a non-negative result on a urine cup?
This question explores situations where legal substances (including medications or even certain foods) might raise alarms.
7. Will a pure CBD product show up as a positive for THC on a urine cup?
With clients increasingly using over-the-counter CBD products for sleep, anxiety, or pain, it’s important to know whether they pose a testing risk—and how to discuss it with them.
8. If you have antibodies for a Blood-Borne Virus (BBV), what does that mean?
You might be surprised how many professionals confuse antibodies with active infection. Understanding this difference is crucial, especially in housing and rehabilitation contexts.
9. How soon after infection can a rapid test detect antibodies for a Blood-Borne Virus (BBV)?
Testing too early can result in a false negative due to the window period. This question checks whether you’re thinking in timelines—not just test kits.
10. What is the primary purpose of the control line on a rapid Blood-Borne Virus (BBV) test?
If the control line doesn’t show, the test isn’t valid—simple but often overlooked in rushed or pressured environments. Don’t skip this step.
