Saliva Drug Testing
Saliva drug testing is a fast, non-invasive method used to detect recent drug and alcohol use. It’s especially effective for identifying current or very recent impairment, making it a preferred choice for post-incident, reasonable suspicion, and roadside testing.

✅ Lab-confirmed results with legally defensible documentation

Not quite yet. While the DOT has officially approved saliva (oral fluid) testing as an alternative to urine under 49 CFR Part 40, it’s not fully implemented yet. We’re still waiting for certified labs to be approved by HHS (Department of Health and Human Services) before DOT saliva testing can be used in practice.
Once those labs are certified, saliva testing will be available — but for now, urine remains the standard for DOT-regulated programs.
