Nationwide Oral Fluid Testing

Saliva Drug Screen / Oral Fluid-Based Drug Screen

Saliva / oral fluid-based drug tests can generally detect use during the previous few days. Saliva or oral fluid based drug tests are becoming more prevalent because of their convenience and the fact that they can not be adulterated. Furthermore, on-site oral based tests in particular enable the implementation of random testing programs, proven to be the most effective type of drug screening. Oral fluid based tests are as accurate as urine and can be obtained from quality suppliers in the United States. Testing is usually performed by employers, for either pre-employment, random, post-accident, reasonable suspicion, or return-to-duty testing. Oral fluid based testing most closely mimics results found with blood and is preferable for detecting on-the-job drug use or in post-accident applications in this case because the degree of intoxication can be approximated based on the amount of substance in the blood. 

Detection in Saliva Tests Begins Immediately Upon Use:

  • Marijuana and Hashish (THC): 1 hour after ingestion, up to 24 hours.
  • Cocaine (including crack): From time of ingestion up to 2 to 3 days.
  • Opiates: From time of ingestion up to 2 to 3 days
  • Methamphetamine and Ecstasy (MDMA, "Crank," "Ice"): From time of ingestion up to 2 to 3 days.
  • Benzodiazepines: From time of ingestion up to 2 to 3 days.

Laboratory testing includes collection of the sample, transport to the laboratory, EMIT analysis, GC/MS confirmation by a SAMHSA-certified laboratory and a test review by a Medical Review Officer, if required.
