As organizations explore different workplace drug testing methods, two questions often come up: Is saliva drug testing accurate? And just as important, is it defensible?
Modern oral fluid drug tests use validated screening technology designed to detect specific substances at established cutoff levels. These thresholds are developed to promote consistency across testing environments and to reduce the likelihood of inaccurate screening results.
Like other drug testing methods, saliva testing typically follows a two-step process. The initial screening provides rapid results, often within minutes, making it practical for workplace programs that require timely insight. When necessary, non-negative screening results can be sent to certified laboratories for confirmatory testing using advanced analytical methods.
Defensibility also depends on how testing programs are implemented. Clear workplace policies, proper collection procedures, and adherence to applicable regulations all play a role in ensuring that drug testing results are handled appropriately.
Another factor supporting defensibility is the observable collection process. Because oral fluid samples are typically collected in plain view, the chain of custody can be easier to maintain compared with methods that rely on private specimen collection.
No testing method is perfect in every scenario. However, when used as part of a structured and compliant program, saliva drug testing can offer a reliable and practical option for many employers.
Fact Friday takeaway:
When supported by proper policies, procedures, and confirmatory testing, saliva drug testing can be both accurate and defensible in workplace screening programs.
