Test ID TOSU Targeted Opioid Screen, Random, Urine
Additional Testing Requirements
In most cases, no additional testing is needed after the qualitative targeted opioid test is performed if the parent/metabolites found are consistent with the patients prescribed medications. However, if unexpected opioid parent/metabolites are found, confirmatory testing can be requested at an additional charge.
