Does on-site urine toxicology screening have an added diagnostic value in psychiatric referrals in an emergency setting?
In an ER setting, the validity of the diagnosis of drug abuse exclusively based on psychiatric interview is low. The use of on-site UTS provides accurate data on drug use and is more practical as compared to post hoc laboratory assessment. On-site UTS has an added diagnostic value of drug use with high sensitivity and specificity.
