Drug overdose deaths increased dramatically from 1980 to 2016, causing a world-wide opioid epidemic. Urine drug testing (UDT) is an effective tool in pain management to monitor compliance with prescribed medications.(1) National guidelines recommend UDT not only to assess compliance but also to detect undisclosed substances and diversion.(2)
