Common questions
Answers before you visit
Is a DOT drug test the same as a regular drug test?
No. DOT tests must remain separate from Non-DOT tests and follow 49 CFR Part 40 plus the applicable DOT agency rule.
What drugs are included in a DOT test?
The federal DOT panel covers marijuana metabolites, cocaine metabolites, amphetamines, opioids and phencyclidine (PCP).
Can an instant test be used for a DOT drug test?
No. Point-of-collection instant drug testing is not authorized for a DOT drug test. DOT specimens must follow the authorized laboratory process.
Do CDL drivers need a pre-employment DOT test?
An employer generally must receive a negative pre-employment drug-test result before allowing a covered CDL driver to perform safety-sensitive functions.
Do you accept walk-ins?
Most drug-test collections accept walk-ins during regular weekday hours. Call before coming for Saturday, mobile or after-hours service.
