DOT-Compliant Testing for Safety-Sensitive Employees

We offer mobile testing collections, so your employees can get tested quickly and conveniently, minimizing downtime and keeping your business moving.

🔹 5-Panel DOT Drug Test
Mandatory drug screening that tests for:

  • Marijuana (THC)
  • Cocaine

Our Non-DOT Testing Services:

🔹 Non-DOT 5-Panel and 10-Panel Drug Testing
Customizable drug panels based on your company’s needs. In addition to our standard drug testing panels, we offer ETG (Ethyl Glucuronide) urine testing to detect recent alcohol consumption. ETG testing can identify alcohol use up to 80 hours after ingestion, making it a valuable tool for zero-tolerance programs, court-ordered testing, or workplace compliance. 

🔹 Pre-Employment Testing
Protect your workplace by screening potential new hires.

🔹 Random Testing Programs
Deterrence and detection of substance abuse in the workplace.

🔹 Reasonable Suspicion Testing
Support your policies by testing employees based on behavioral indicators.

🔹 Post-Accident Testing
Ensure safety by testing employees involved in workplace incidents.

🔹 Return-to-Duty Testing
Help employees reintegrate after a policy violation or rehabilitation program.
