An instant [urine](https://amhnationwide.com/urine-drug-testing/) drug screen is a rapid test that detects the presence of specific drugs or their metabolites in a urine sample. It uses immunoassay technology to provide preliminary results within minutes at the collection site. This test is commonly used for workplace screening, clinical assessments, and legal purposes. LAB NETWORKS ## Which labs process the instant urine drug screen for AMH Nationwide? AMH Nationwide directs all instant urine drug screen collections 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. These labs follow strict protocols to ensure accurate and timely results. TEST ACCURACY ## How accurate is the instant urine drug screen and what happens if the result is non-negative? The instant urine drug screen is highly sensitive but can produce false positives or negatives. Therefore, every non-negative result undergoes confirmation and review by a certified Medical Review Officer (MRO) as part of standard processing. Confirmatory testing typically uses more specific methods such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). DOT COMPLIANCE ## Is the instant urine drug screen used for DOT-regulated testing? For DOT-regulated safety-sensitive positions, AMH Nationwide requires the federally certified urine testing protocol under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). The instant urine drug screen can serve as a preliminary screen but the final DOT test must follow the strict urine chain of custody and laboratory certification requirements. Hair testing is not accepted for DOT roles. ## Need an Instant Urine Drug Screen? Call (877) 731-6362 to schedule your test or get information on collection sites and pricing.
