Frequently Asked Questions

On-site drug testing means a certified collector travels to your workplace, job site, accident scene or other location to perform drug, alcohol or DNA tests, rather than sending employees off-site. The testing event uses urine, saliva or hair specimens (depending on panel), and can include breath alcohol screening. Accredited Drug Testing offers this service 24/7 nationwide.
Industries that commonly use on-site testing include construction sites, manufacturing plants, power plants, motor pool facilities, car dealerships, trucking/transportation companies, schools, hospitals, and oil & gas drilling sites.
Available test types include urine drug panels (5-panel, 10-panel, etc.), saliva/oral fluid tests, hair follicle testing, rapid/instant screening and breath alcohol testing (BAT). For DOT-regulated employees, full chain-of-custody and DOT-compliant documentation is provided.
Key benefits include convenience (the collector comes to your location), minimal downtime for employees, faster response especially for post-accident or reasonable-suspicion testing, and improved compliance because the service provider handles certified collectors, forms and documentation.
When scheduling, you’ll specify number of people to be tested, location, time and type of tests needed (DOT or non-DOT). The provider sends certified collectors with all required supplies, privacy setup, chain-of-custody forms, and testing is conducted onsite. After completion, samples are sealed, transported to a SAMHSA-certified lab if needed, and results reported to the employer.
Yes. Accredited Drug Testing’s on-site service supports all DOT modes (FMCSA, USCG, FAA, PHMSA, FRA, FTA), uses certified collectors, provides full documentation including chain of custody, and supports random, post-accident, return-to-duty and other regulatory scenarios.
