VINScreen GHB – Gamma-Hydroxybutyric Acid Rapid Urine Test Cassette
Single-panel urine cassette for rapid qualitative detection of GHB (gamma-hydroxybutyric acid) at a cut-off of 10 μg/mL.Suitable for professional screening environments, including emergency, forensic, correctional, and investigative settings, VINScreen GHB offers a simple visual result to help guide next steps.
Panel & Cut-Off
GHB — 10 μg/mL
Enzyme-based biochemical assay with colour-card comparison for semi-quantitative reading (10–50+ μg/mL range).
Why GHB Testing Matters
GHB is rapidly metabolised — typically undetectable in urine after ~12 hours and in blood after ~6 hours. Early collection and rapid onsite screening are critical to detection.
Best For
Emergency departments, forensic investigation units, sexual assault response teams, law enforcement, drug rehabilitation programs, and clinical toxicology.
How This Test Works — Enzyme-Based Colour Change
Unlike standard immunoassay strip tests, the VINScreen GHB cassette uses an enzyme-based biochemical reaction. When GHB is present, the reaction pad changes from colourless to purple. The intensity of the colour corresponds to GHB concentration — compare the pad against the included colour card to estimate the level (10 μg/mL light purple → 50+ μg/mL dark purple).
Performance & Accuracy
| Metric | Result |
|---|---|
| Positive detection at cut-off (10 μg/mL) | 100% (30/30) |
| Negative at 0% & −50% cut-off | 100% (30/30) |
| Multi-site precision (3 labs, 3 lots) | Consistent across all sites |
| Read time | 10 minutes |
| Sample type | Urine |
| Sensitivity (cut-off) | 10 μg/mL |
Screening results are preliminary. Confirm any positive result by GC/MS as required by your protocol.
How to Use
- Allow the test cassette and urine specimen to reach room temperature (15–30°C).
- Remove the cassette from the sealed pouch and use within one hour. If the reaction pad already shows a purple colour before applying the sample, do not use — discard and open a new cassette.
- Place the cassette on a clean, level surface. Hold the dropper vertically and transfer 3 full drops of urine (approx. 120 μL) to the specimen well (S).
- Start the timer. Avoid trapping air bubbles in the specimen well.
- Read results at 10 minutes by comparing the reaction pad colour against the included GHB colour card. Do not interpret results after 15 minutes.
How to Interpret Results
- Negative: No colour change on the reaction pad, or colour is lighter than the 10 μg/mL reference on the colour card. GHB concentration is below 10 μg/mL.
- Positive: Reaction pad changes to purple. Light purple indicates ~10 μg/mL; dark purple indicates 50 μg/mL or higher. Compare against the colour card for an estimated concentration.
- Invalid: If the reaction pad shows purple colour before the urine sample is applied, discard the cassette and retest with a new device.

FAQ
What is GHB and why is rapid testing important?
GHB (gamma-hydroxybutyric acid) is a central nervous system depressant associated with drug-facilitated sexual assault. It is rapidly metabolised — typically undetectable in urine after approximately 12 hours — so early specimen collection and rapid onsite screening are critical.
How does this test differ from standard drug test strips?
This is an enzyme-based biochemical assay, not an immunoassay. Instead of reading lines, you observe a colour change on the reaction pad and compare it to the included colour card. Purple = positive; no colour = negative.
