Saliva Drug Test FAQ

Frequently asked questions regarding saliva drug testing

What are the detection windows for the drugs in saliva?

Detection times for oral fluid testing ( saliva ) depend on the brand of drug test used and the drug test, but as a general rule, drugs are usually only detectable on a saliva test, for up to 48 hours after last use. Cannabis and methadone have a very short detection period in the saliva of about 12-14 hours.

Is there is there any specific time that I should carry out the saliva drug test?

An oral saliva drug testing kit can be performed at any time of day but must be at least 20 minutes after the individual last ate, drank or smoked or put anything in their mouth.

How do you perform a saliva drug test with a test kit?

The drug test is performed using a mouth swab drug test kit that is then either inserted into a container with an inbuilt drug screen, or the swab is actually built into the drug test kit ( a direct saliva drug test kit). Some of the new direct saliva drug testing kits are even easier to perform as the drug test is incorporated directly into the swab and they have a saliva indicator to show when enough saliva has been absorbed. The direct saliva drug test kits are currently only available for 6 drug groups or less.

You then get an individual result for each drug group tested. It is a screening drug test, and you would need to send a laboratory confirmation chain of custody urine or saliva drug test (this has to be sent away) to confirm any positive results if you are performing the saliva drug test in a workplace setting.

How long do the results take with a saliva drug testing kit?

A saliva test kit is an instant near patient test which means you get the results within minutes of performing the drug test. If the result is negative you do not need to do anything else. If you are performing the saliva drug test in a workplace setting you should then confirm all positive results using a laboratory confirmation chain of custody urine drug test (this has to be sent away)

I see you have a saliva test that shows if someone has had Cannabis within the last 12 hours, do you have these for other drugs such as Cocaine?

We also have single saliva drug test kits for Cocaine

and saliva drug test kits for Cotinine (Nicotine and smoking detection)

All the saliva drug testing kits have a shorter window of detection than the urine drug tests are ideal for workplace drug testing where you wish to know if someone is under the influence of drugs while at work or if you need to establish if someone has appropriate levels to return to work if they have taken a drug. The window of detection for most drugs including Cannabis and Cocaine in saliva is up to 12-14 hours.

Are there any mouth swab or saliva drug test kits that detect drugs for longer periods?

The simple answer is no. The detection times for drugs in saliva is very short when compared with urine drug testing kits.

Which oral drug and alcohol testing kits are best for the workplace?

The 12 in 1 oral fluid mouth swab saliva drug & alcohol testing kit is the most comprehensive oral drug & alcohol test kit. It tests for 11 drugs plus alcohol on one drug test kit and is an ideal choice for a workplace saliva drug test.

What action do we need to take if one of these saliva drug tests should prove positive?

The saliva drug test kits are drug screening tests. If the test results are negative you do not need to do anything further. If the drug test result is not negative, what you do depends on your drug and alcohol policy.

If you intend to take any disciplinary action on the basis of the results, then you would need to do a GCMS lab confirmation urine drug test with a chain of custody. Most companies keep at least one lab pack in stock for when they get a non-negative drug screening result.
