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.
