Laboratory Based Oral Fluid (Saliva) Testing

With oral fluid testing, saliva samples are tested for parent drugs and their metabolites. An absorbent collection device is placed in the mouth and the saliva collected is screened for drugs of abuse in the laboratory.  Samples are checked to verify the saliva is human. Oral Fluid offers a substance detection time frame similar to urine and blood testing, but oral fluid samples do not require special collection facilities or working with hazardous bodily fluids.

It is important to note that our oral fluid testing is a completely laboratory based process.

While some instant oral fluid collection devices may be available, they are often not properly FDA-cleared and lack the sensitivity required to detect usage of certain drug classes. It is for these reasons that a laboratory-based process must be used in order to secure valid results. 

Why Choose Oral Fluid versus Urine Drug Testing?

Oral fluid testing can detect drugs immediately after the most recent use and up to 4 days later. Conventional drug testing with urine is unable to detect usage in the first four hours after use.

The use of oral fluid combined with the high-precision testing instruments used by our Laboratories offers many benefits over other types of testing methods. When comparing saliva drug tests vs urine drug tests, consider the following advantages and how they will benefit your hospital, clinic, office or lab.

  • Early Detection Window
  • Deeper Insight into Drug Levels
  • Strong Correlation to Impairment
  • Greater Integrity of Results
  • A Better Process for Collection
  • Oral fluid testing is easy to administer.
  • Observed collections can occur with every test creating trust in the process as both the test administrator and the donor have full view of the specimen every step of the way.
  • It eliminates the need for the myriad precautions needed with urine testing such as putting blue dye in toilet water, turning off the hot water and asking donors to leave their jacket or purse in another room while the collection takes place.
  • “Shy bladder” issues, which can be time consuming and embarrassing for the donor are eliminated.
  • Urine testing is often considered “yucky” by those who are not used to handling another person’s urine, thus oral fluid testing eliminates the “yuck” factor commonly associated with urine testing.
  • Lab-based oral fluid drug testing has proven to be scientifically accurate (the equivalent to a urine screening test) and more effective at detecting recent drug use.
  • Lab-based oral fluid drug testing is legally defensible.
  • Oral fluid testing is virtually adulteration proof, regardless of the cheating method (adulteration, substitution or dilution).
