Drug Testing

Drug Screen
A DOT drug screen tests a specimen for five drugs — opiates, PCP, amphetamines/methamphetamines, marijuana and cocaine. A DOT-approved chain-of-custody form is used during the collection process, and a split sample is collected and both specimens are forwarded to the laboratory for testing.

Drug Screen — Non-DOT / FCWP
A non-DOT drug screen can test for the same range of drugs as the 5-panel DOT screen. It can be expanded into a 10-panel drug screen by testing for barbiturates, benzodiazepines, methadone, methaqualone and propoxyphene.

GC/MS
GC/MS testing is considered to be the most definitive method for confirming the presence of a detected substance in urine. GC/MS is used to confirm test results that indicate any level of a controlled substance.

Post-Accident Testing
This refers to testing an employee who is involved in an on-the-job accident that may have involved human error and may have caused a fatality, serious injury, or significant property damage.

Return To Duty Testing
Employees returning from a leave of absence for sickness or injury exceeding a given number of days can be required to submit and successfully pass a drug and/or alcohol test as a condition of reinstatement.

Pre-Employment Testing
A candidate for employment must pass the drug and/or alcohol test as a condition of employment. Testing can be performed before an offer, after an offer but before work begins, or shortly after starting work.

Random Testing
Random testing helps employers maintain a drug-free workplace by selecting employees for testing without prior notice on an unpredictable schedule.

Reasonable Suspicion Cause Testing
Testing conducted when a trained supervisor observes signs or symptoms that suggest an employee may be under the influence of drugs or alcohol.
