Oral Fluid drug testing is the preferred method for post incident or reasonable suspicion situations as it provides a short window for substance detection with little to no potential for adulteration. This drug screen option is extremely convenient as there are very few limitations as to where this test can be administered.

 Canadian Screening offers two oral fluid test options: 

  • Express POCT (Point of Care Test)​ which will provide quick, qualitative, same day result delivery
  • Lab Based Test​ which will provide quantitative court admissible test results in 2-5 business days

An oral fluid drug test has the ability to screen for the following substances: 

  • Amphetamine, Benzodiazepines, Barbiturates , Cocaine , Methamphetamine, Methadone, Opiates,  PCP, Propoxyphene


How long is a substance detectable in an oral fluid sample?

There are several variables that will determine how long a substance will remain detectable in an individual’s oral fluid sample but ultimately, it’s completely dependant on the substance ingested and the individual being tested.

Can Oral Fluid drug testing be selected for reasons besides post incident and reasonable suspicion?

Yes. The method of drug testing is at the discretion of the employer or individual and can be selected for pre-employment, pre-access, random testing etc. However, urine drug testing is the preferred method for pre-employment or pre-access situations as it offers an increased detection timeline.

How accurate is Oral Fluid testing?

Oral Fluid express testing provides a reliable, qualitative, preliminary result, however, a lab based oral fluid test is required to obtain a quantitative, court admissible test result. Canadian Screening offers oral fluid laboratory testing as a secondary method after a non-negative express result is received or as a stand alone service.
