There are currently three primary methods for specimen collection for employers who want to create a safe and healthy workforce through drug screening. Urine testing is used by 90 percent of employers, according to HireRight, with saliva used by 10 percent and hair used by 7 percent. HIreRights Dr. Todd Simo noted that alternate specimens are gaining interest. Both hair and oral fluid testing have had double-digit yearly growth as more companies become aware [of them], he said. Urine and hair testing pick up many different drugs, such as prescription medications, while oral testing panels are typically screening for marijuana, cocaine, PCP, amphetamines and opioids.
