Frequently Asked Questions
What is a DOT urine drug test?
A DOT urine drug test is a federally regulated drug screen required for employees in safety-sensitive transportation positions. The collection must follow 49 CFR Part 40 procedures, the specimen is analyzed at a DHHS-certified laboratory, and results are reviewed by a Medical Review Officer (MRO).
How long do results take?
Negative results are typically reported within 24 to 48 hours after the laboratory receives the specimen. Non-negative results require confirmation testing and MRO review, which can add a few business days. We communicate your results as soon as they are released to us.
Do you come to our facility?
Yes. Mobile on-site DOT collections are one of our specialties. We travel to employer locations across Mid-Missouri, and after-hours service is available from 5pm to 9am for post-accident and other urgent needs.
What should drivers bring?
Drivers should bring a valid government-issued photo ID, such as a driver’s license or CDL, plus any test authorization form provided by the employer. Please avoid excessive fluid intake right before the test and be prepared to leave outer garments, bags, and pocket contents with the collector.
