Type of Drug Test Used By Employers

"When companies were asked what type of drug testing sample they used, the human resource professionals responded that 84% used urine as the sample of choice, with the test performed in an off-site laboratory. Only 24% responded that they used instant urine tests, only 6% used hair testing, and 5% used instant or off-site laboratory oral fluid tests."
