Saliva Drug Test Kits

Which Saliva Drug Test Kit Do You Need?

Our range is deliberately tight: two saliva drug test kits, each strong in a different situation. This table shows the practical differences.

If your program needs drugs and alcohol covered in one step, the DrugSense DSO8 Plus saliva drug test kit is the practical choice: one device, eight drug classes and alcohol, no second test to run. The ToxWipe 7 saliva drug test kit is built around collection comfort. It needs only a small sample and avoids the dry-mouth problem that can stall a test, which matters in frequent or observed testing. Neither kit is a compromise; they solve different problems.

What AS/NZS 4760:2019 Verification Means

AS/NZS 4760:2019 is the joint Australian and New Zealand standard, published by Standards Australia and Standards New Zealand, for procedures associated with the collection and testing of drugs in oral fluid. It sets out how oral fluid samples should be collected and handled, and it specifies target cut-off concentrations that screening devices should detect for each drug class.

When a supplier states a device is “verified to AS/NZS 4760:2019”, it means an independent laboratory has confirmed the device performs against the cut-off concentrations the standard specifies. That is a meaningful check on real-world performance, not marketing shorthand.

Note that AS/NZS 4760 covers oral fluid testing specifically. Urine testing has its own standard, AS/NZS 4308, which is covered on our urine collection page.

Cut-Off Levels Compared

A cut-off is the concentration threshold, measured in nanograms per millilitre (ng/ml), at which a screening device reports a non-negative result. Below the cut-off the test reads negative; at or above it, the sample is flagged for confirmatory testing. Lower cut-offs mean greater sensitivity for that drug class. The supplier-published cut-offs for both kits:

These figures match each product page. The notable differences: the ToxWipe 7 screens benzodiazepines at a much lower threshold (10 ng/ml against 50), while the DSO8 Plus adds synthetic cannabinoids and alcohol that the ToxWipe 7 does not cover.

How a Saliva Drug Test Works

A saliva test is often called a mouth swab drug test, and the process is straightforward:

1. Collect. The donor swabs the inside of the mouth to gather an oral fluid sample. Collection is non-invasive and can be directly observed, which protects sample integrity.
2. Saturate. The swab absorbs saliva until the device indicates a sufficient sample. The ToxWipe 7 needs only a small sample, so dry mouth does not stall the process.
3. Read. Results appear in the device window in around 10 minutes, with a separate line for each drug class on the panel.

There are no needles or collection cups involved, and because collection can be watched without any privacy intrusion, oral fluid screening has become the default for on-the-spot workplace testing.

Detection Windows: What a Saliva Test Can and Can't Tell You

Saliva testing detects recent use. As a general guide, THC is detectable in oral fluid for roughly 12 to 24 hours after use, and most stimulants and opiates for roughly 24 to 48 hours, depending on the drug, dose and pattern of use. These are approximate screening ranges, not guarantees; heavy or frequent use can extend them, and individual results vary.

That short window is the point. A saliva screen answers “has this person used recently?”, which is usually the question that matters in a safety-critical workplace. It does not reveal use from last week the way a urine test might, and a good testing policy treats that as a feature rather than a shortcoming. The DrugSense DSO8 Plus also screens alcohol at 0.02% BAC in the same test, so a single saliva drug test kit can cover both recent drug use and alcohol in one collection.

Be equally clear about the limits. A screening result is indicative only. It is not legally definitive and it is not proof of impairment. Any non-negative result should be treated as preliminary and sent for confirmatory laboratory testing before decisions are made on it.

Saliva vs Urine Drug Testing

Oral fluid and urine answer different questions. Choose a saliva drug test when you need to detect recent use, want directly observed collection without privacy issues, and need results on the spot with minimal facilities. Choose urine when a longer detection window matters, such as pre-employment screening, where use over previous days is relevant. Neither method is universally better; the right choice follows from what your policy is trying to establish. Urine testing in Australia is covered by its own standard, AS/NZS 4308, and our urine drug test kits are specified against it.

Many workplace programs run both: saliva for random and for-cause testing where recency is the concern, urine where a broader look-back is appropriate. If you are unsure which fits your policy, call us on 03 9360 0780 and we will talk it through.

Saliva Drug Testing for Australian Workplaces

The saliva drug test kits in this collection support an AS/NZS 4760-aligned workplace testing program. They suit random, for-cause and post-incident testing, where observed collection and a 10-minute result keep disruption to a minimum. The kits are one component; a defensible program also needs a written policy, a trained collection procedure and a confirmatory testing pathway. We supply the hardware and consumables to enable that program, and we are straightforward about the fact that no device on its own makes a workplace compliant.

We also stock a chain of custody book for documenting sample handling from collection through to the laboratory. For larger testing programs, or a quote covering both saliva and urine kits, contact our team and we will put together pricing for the volumes you need.
