Negative
A control line and a test line are visible. A faint coloured test line also counts as negative when the control is valid and the result is read correctly. This does not exclude all drug use.

VivaTest · Know your test
A focused cannabis urine screen.
A single-target urine test for cannabis-related metabolite screening at a stated cut-off of 50 ng/mL. Designed for a focused THC screen rather than a multi-drug panel.
- Urine
- 1 drug panel
- Preliminary screening
01 · Screening coverage
What does this test screen for?
The listed panels and cut-offs for this urine test are shown below. Match these to the substances you need to screen.
| Code | Screening target | Cut-off (ng/mL) |
|---|---|---|
| THC | Cannabis (THC) metabolite screen | 50 |
Use the codes, reference substances and thresholds on the supplied device and leaflet for your test. Different sample types and panels can use different cut-offs.
02 · Collection & timing
Urine dip test: how it works
A practical overview. Read the complete supplied instructions before opening the test; they specify sample quantity, collection time and the valid reading window.
-
Prepare
Check the expiry date and sealed pouch. Bring the test and sample to the temperature specified in the leaflet and have a timer ready.
-
Collect the sample
Collect urine in a clean, dry container. Remove the test cap and immerse only the exposed test ends to the marked depth for the duration in the leaflet.
-
Let it develop
Remove the test from the sample, replace the cap if directed and place it flat. Start timing at the step specified in the leaflet.
-
Read each panel
Read the result at 5 minutes after starting the test. Use the supplied leaflet for the final reading window; ignore changes after that window.
Read at 5 minutes
After starting the test, read at 5 minutes. Follow the supplied leaflet for the final interpretation window.
03 · Reading the drug panels
Know what the lines mean
Interpret each drug panel independently, within its valid reading time. C is the control line; T is the drug test line. Match the positions to the printed guide on your device.
Presumptive positive
The control line is visible and the test line is absent for that panel. This is an initial screening result. A more specific laboratory method is needed to confirm it.
Invalid
The required control line has not appeared, with or without a test line. Do not interpret that panel. Review the instructions and repeat using a new device.
Illustrative drug-panel examples only. Some devices share a control across several drug lines; follow the layout in the supplied leaflet. Line darkness does not measure how much drug is present.
04 · Put results in context
A screening result is a starting point
These tests provide preliminary qualitative information. Consider the panel coverage, sample collection and circumstances alongside the result.
Confirm positive screens
Arrange a more specific laboratory confirmation method, such as GC-MS or LC-MS/MS, before making consequential medical, employment or other decisions. Seek qualified interpretation.
Understand a negative
A negative screen does not prove that no substance was used. The substance may not be on the panel, may be below the cut-off, or may no longer be detectable in that sample.
Keep the wider picture
Rapid screens do not determine a dose, exact time of use, dependence or impairment. Medicines and other substances can affect some assays. Do not stop prescribed medicines on the basis of this test.
For workplace screening: use appropriate consent, a clear policy, trained handling and procedures suited to your purpose. A rapid screen alone is not a fitness-to-drive or fitness-for-duty assessment. Read HSE guidance on screening and testing (opens a new tab).
05 · Meet the range
Find the screening format you need
Choose by sample type, individual screening targets and intended use. A higher panel count is useful only when its coverage matches your requirements.
