Saliva laboratory drug testing

The saliva laboratory drug test (oral-fluid drug test) is an accredited alternative to urine laboratory drug testing. As a result, laboratory reports from this drug test are court admissible. Furthermore, it has an effective drug detection window for the average person of up to *two days, and is a popular method for random drug testing in the workplace. * Dependant on multiple factors.

How does saliva laboratory drug testing work?

After taking a drug, it enters a person’s bloodstream. Next, the drug is metabolised within the body, and what remains of the drug is excreted from the body. One type of excretion is through saliva, so this enables us to analyse the metabolites of drugs using saliva samples.

First, we perform a screen of the sample in the laboratory. The laboratory screen is very accurate and provides an advantage over the saliva Point of Care Test (POCT). The screen results take 1 to 2 working days from the appointment. If nothing is detected in the screen, we will issue a negative (Pass) report. But if the sample screens non-negative, the sample will go on for confirmation drug testing. In this case we will issue an ‘Undergoing Further Analysis’ notification.

Frequently Asked Questions

What happens at the saliva laboratory sample collection?

We perform the saliva laboratory sample collection using strict chain of custody procedures. 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. Two saliva samples are taken and will be labelled as A and B samples, while written consent is also obtained from each donor. Finally, samples and documentation are sent securely to the laboratory for analysis.

What is laboratory confirmation drug testing?

Confirmation drug testing will identify the drug or metabolite found in the sample. Also, it will determine the quantity of the drug present. This process can take up to a further three to five working days.

Next, if the presence of the drug is over a specific cut-off level, we will issue a positive lab report. This could provide evidence of abuse.

In this case, the report may specify whether the drug and its quantity are therapeutic. For instance, in line with declared medication. To confirm this, we may also offer an optional Medical Review Service.

Why use the saliva laboratory drug test?

The saliva laboratory drug test is an accredited legally defensible method. For example, the laboratory test report can be used as evidence in a disciplinary process, employment tribunal or for court purposes.

Other advantages of the saliva laboratory drug test:

  • Regarded as a fairer test in the workplace due to the short detection window of up to 48 hours.
  • Less invasive than urine testing. Also, secure toilet facilities are not required.
  • Takes less time than urine testing. For example, ‘shy bladder’ issues cause delays when collecting urine samples.
  • Difficult to cheat a saliva drug test. This is because the collection officer will witness the sample collected. As a result, this removes the chance of adulteration or substitution.
What is the detection window for laboratory saliva drug testing?

Many factors affect the length of time that this test can detect a certain drug in the body. These factors include:

  • body mass.
  • hydration levels.
  • how long ago the person took the drug.

Also, other variables could include gender, age and even genetics.

If a person uses a drug often or in large quantities, a saliva drug test could detect it for a longer period.

What drugs can we test for?

As standard, we can analyse the following drug groups for this test:

  • Amphetamines, including Methamphetamine and Ecstasy (MDMA)
  • Benzodiazepine (including Diazepam and Temazepam)
  • Cannabis
  • Cocaine
  • Opiates
What are cut-off levels?

Saliva laboratory drug tests use cut-off levels. This means that a result will only be positive if the amount of the drug is above a certain level. Cut-off levels follow EWDTS guidelines. Having cut-off levels helps prevent false-positive results. For example, they reduce the chance of testing positive after only passive exposure to a drug.

What is the cost of the saliva laboratory drug test?

The cost per person can be very competitive depending on the number of individuals attending the appointment. This can be as little as £60 per person, including a breath alcohol test. Appointments for single individuals at a clinic start from £180.

Also, the price of an optional medical review to confirm positive drug confirmations is £120. This could confirm that declared medication is in line with a therapeutic use.

Prices quoted include VAT.
