How does Instant Saliva Drug Testing work?

After consuming a drug, it enters a person’s bloodstream. Next, the drug is metabolised within the body. After this, what remains of the drug gets excreted out of the body. One method of excretion is through saliva. As a result, this enables us to analyse the metabolites of drugs in the saliva.

First, the saliva sample is obtained and collected using a mouth swab device. The screen within the device is activated by the collection officer. Results of the screen can usually be observed around 5 minutes after activation. Next, the collection officer will read and record the results on the chain of custody document. A non-negative result could be an indication that a metabolite of the drug group may be present in the saliva sample. In this case, and if authorised to do so, we will obtain a fresh saliva sample and dispatch this to the laboratory. In this case, the sample will undergo a saliva laboratory drug test. Furthermore, it is important to do this if the results are to be legally defensible.

The screen analysis is undertaken against predetermined cut-off levels for all drugs tested.

The standard panel includes 6 drug groups:

  • Cocaine
  • Amphetamine
  • Benzodiazepine
  • Cannabis
  • Methamphetamine
  • Opiates


Saliva Drug Test Process

We perform this test under strict chain of custody protocols. Also, the collection is undertaken by trained and certified sample collection officers. In addition, identification takes place by obtaining official ID such as passport or driving licence. Also, we provide the drug test results at the appointment. Whereby a copy goes to the donor and one going to the donor’s organisation/employer, if applicable. Beforehand, the trained collection officer will interpret the analysis from the saliva collection device. Next, they decide on whether the sample needs further analysis at the lab. But this is depending on authorisation being in place to do so.

The detection window for drugs in saliva is up to two days depending on the drug. Also, alcohol testing is available in conjunction with this test. For example, a breathalyser screen provides evidential alcohol results.

In addition, the above process is compliant with ISO 9001, ISO 27001 and ISO 14001. As a result, GDPR compliance is assured.


When to use Saliva Drug Testing?

Instant saliva drug testing is a cost effective and prompt method of determining very recent drug use. Screening results are available within minutes of sample collection. Also, it is a popular testing method in the workplace. For instance, within industry and commercial organisations for random drug testing programmes.

Many organisations choose this option as it provides the following benefits:

  • Instant screen results providing an early sign of drug abuse. For example, when results are time sensitive and required for quick deployment of personnel
  • Cost effective
  • Suitable for mass screening of workforce
  • Quality device providing reliable initial signs of drug abuse
  • Less invasive than urine testing and less prone to adulteration or substitution of the sample.


The pros and cons of Saliva Drug Testing

There are many benefits in using this test. Yet, there are limitations that you must consider before deciding if this is the right one for your circumstances.

These include:

  • Accuracy of the test compared to saliva laboratory screen and confirmation drug test. The laboratory test is performed in a UKAS 17025 accredited facility when analysing the samples.
  • False positive and negatives can occur. We recommend lab analysis for all non-negative results from a POC screen. Only the confirmation testing at the laboratory is legally defensible.
  • What if there is a large amount of non-negative test results? In this case the extra cost to confirm the results may outweigh any initial cost benefits.
  • Taking disciplinary action based on POC Test results is not advisable. Instant oral-fluid drug testing is not legally defensible due to potential false negative or positives. Laboratory confirmation testing must be undertaken before making any disciplinary decisions.
  • The detection period is very short (up to two days). If you need a longer period of analysis, it may be worth considering urine or hair drug testing.

So there are many things to consider for this option. But this is an effective method for certain circumstances. Please speak to our team who will talk you through the pros and cons.
