OVERVIEW ## What is the ExperTox unknown drug panel? The ExperTox unknown drug panel is a broad-spectrum drug test designed to detect a wide variety of substances, including prescription medications, illicit drugs, and synthetic compounds. It uses hair or [urine](https://amhnationwide.com/urine-drug-testing/) specimens to provide detailed results. This panel is among the broadest offered, covering more substances than typical drug screens. ORDERING ## Who typically orders the ExperTox unknown drug panel? Employers, medical professionals, legal authorities, and rehabilitation centers commonly order the ExperTox unknown drug panel. It is used when comprehensive drug screening is necessary, such as in [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) checks, clinical assessments, legal cases, or monitoring substance use in treatment programs. DETECTION ## What is the detection window for the ExperTox unknown drug panel? The [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/) depends on the specimen type. Urine testing typically detects drugs used within the past 1 to 4 days. Hair testing extends the detection window up to 90 days, capturing drug use over a longer period. The specific substances detected and detection times vary by panel configuration. COLLECTION ## How is the specimen collected for the ExperTox unknown drug panel? Specimen collection for the ExperTox unknown drug panel is routed through five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, and ExperTox. Collection sites are selected based on the requester’s location. The test requires in-person specimen collection at an authorized facility; there is no online ordering or at-home collection. Urine collection follows standard protocols for drug screening. Hair collection involves cutting a small sample close to the scalp. DOT-regulated testing requires federally certified urine protocols under [49 CFR Part 40](https://www.transportation.gov/odapc/part40); hair testing is for non-DOT roles. ## Ready to schedule your ExperTox unknown drug panel?
