Since 1995, U.S. Drug Testing Services has been performing on-site collections coast to coast. Ten years ago, services expanded to provide on-site post accident and reasonable suspicion testing 24 hours a day, 7 days a week. Our Clients include trucking, railroad, airline, construction, and maritime shipping companies, as well as several TPAs and Labs.

Collections are performed using standard lab kits only (singles or splits), and all specimens (DOT or NON-DOT) are collected according to strict DOT urine collection protocol. All on-site collectors and breath alcohol technicians (BATs) utilized by U.S. Drug Testing Services are certified in accordance with DOT protocol. Our database contains over 1000 collectors and BATs spread out over the entire country. We also have coordinated on-site collections in Canada, and overseas.
