Urine Testing

Workplace Screening Intelligence offers Urine testing as well as many other specimen types. Urine testing detects recent use, typically in the previous one to three days, however, longer detection is normal for chronic marijuana smokers. Urine testing is the only method of testing approved for federally mandated testing such as strict DOT and FMCSA guidelines. 

Employers will use urine drug testing for its cost-effectiveness and capacity to screen for a wide variety of drug substances.
