What Is a DOT Urine Drug Test?
DOT urine drug testing is required by federal law for employees in safety-sensitive positions regulated by:

​

• FMCSA (Federal Motor Carrier Safety Administration)

• FAA (Federal Aviation Administration)

• FTA (Federal Transit Administration)

• PHMSA (Pipeline & Hazardous Materials Safety Administration)

• FRA (Federal Railroad Administration)

These drug tests follow strict chain-of-custody protocols and must be conducted by a DOT-certified collector — like us. All samples are sent to SAMHSA-certified laboratories for processing and are reviewed by a Medical Review Officer (MRO) before results are finalized.
 

 

What Substances Are Screened?
Our standard DOT 5-Panel Urine Drug Test screens for:
 

• Marijuana (THC)

 

• Cocaine

 

• Opiates (including codeine, heroin, morphine)

 

• Amphetamines (including methamphetamine)

 

• Phencyclidine (PCP)

For Non-DOT tests, additional panels (such as 10-panel or customized screenings) can be arranged upon request, covering substances like benzodiazepines, barbiturates, methadone, ecstasy (MDMA), and more.
 

 

Who Needs a DOT Urine Drug Test?

• Commercial drivers (CDL holders)

​

• New hires in safety-sensitive positions

 

• Employees returning to duty after a violation

 

• Individuals in follow-up or random testing pools

​

• Federal contractors or transportation workers

 

 

What Is a Non-DOT Urine Drug Test?
A Non-DOT urine drug test is used for:
 

• Pre-employment screenings

 

• Post-accident testing

 

• Probation or court compliance

 

• School athletics

 

• Workplace testing programs

​​

• Personal or family concerns

These tests are not federally regulated and offer more flexibility in panel types, testing frequency, and collection procedures.
