Learn how on site drug testing works. Call (877) 731-6362 for details. --- Onsite drug testing provides a rapid drug screen at approved collection sites nationwide using federally certified protocols and multiple national lab networks. This testing offers fast results reviewed by a certified Medical Review Officer to ensure accuracy. Call (877) 731-6362 to schedule or learn more about onsite drug and alcohol testing. OVERVIEW ## What is onsite drug testing? Onsite drug testing is a method of collecting and screening specimens for drugs or alcohol at a local collection site near the requester. AMH Nationwide coordinates collection 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. The process includes rapid drug screening with results typically available within 24 to 48 hours, depending on the test panel. The testing covers a variety of specimen types including [urine](https://amhnationwide.com/urine-drug-testing/), oral fluid, and hair, with rapid drug tests commonly performed on urine or oral fluid. Every non-negative screen undergoes review by a certified Medical Review Officer to confirm accuracy and interpret results. TEST TYPES ## What types of onsite drug testing are available? AMH Nationwide offers several onsite drug testing options tailored to different needs. The most common onsite drug tests include urine drug screens, oral fluid rapid drug tests, and hair testing for longer detection windows. Urine and oral fluid tests provide fast drug test results ideal for [pre-employment](https://amhnationwide.com/pre-employment-hair-testing/) or random screening. Hair testing is not typically conducted onsite but is ordered through the same network and is useful for detecting drug use over a longer period. DOT-regulated safety-sensitive testing requires federally certified urine collection under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). Hair tests are generally used for non-DOT roles. Urine Rapid Drug Test: Detects recent drug use, common for workplace and court testing. Oral Fluid Rapid Drug Screen: Non-invasive, fast, and suitable for instant drug testing. Hair Testing: Longer [detection window](https://amhnationwide.com/hair-follicle-drug-test-detection-window/), used for ongoing monitoring, not typically onsite. PROCESS ## How does onsite drug and alcohol testing work? Onsite drug and alcohol testing begins with AMH Nationwide providing a lab order and directing the requester to a nearby collection site. There is no online ordering; all requests must be made by phone at (877) 731-6362. At the collection site, trained personnel collect the specimen under chain of custody procedures ensuring sample integrity. The specimen is then routed to one of five national lab networks for analysis using federally certified methods. Non-negative results are reviewed by a Medical Review Officer before final reporting. Alcohol testing may use breath or urine samples depending on the program. ADVANTAGES ## What are the benefits of onsite drug testing compared to other methods? Onsite drug testing offers several advantages including speed, convenience, and nationwide availability. Rapid drug screening provides quick preliminary results while maintaining accuracy through certified lab analysis. Using established lab networks ensures reliability and compliance with regulatory standards. Compared with home or unregulated kits, onsite testing reduces the risk of tampering or false negatives. The involvement of a Medical Review Officer adds an expert layer of review uncommon in instant test kits. Fast turnaround times, often within 24-48 hours Access to over 20,000 nationwide collection sites Certified lab analysis with Medical Review Officer oversight Compliance with DOT and other regulatory standards Multiple specimen types available depending on need ## Ready to Schedule Onsite Drug Testing?

Detection windows vary by specimen type and drug class. Urine rapid drug tests typically detect drug use within the past 1 to 4 days depending on the substance. Oral fluid rapid drug screens detect more recent use, usually within 24 to 48 hours. Hair testing detects drug use over a longer period, up to 90 days, but is not generally performed onsite. AMH Nationwide uses scientifically validated methods to ensure detection is accurate based on the specimen and test panel. It is important to select the right test type for the detection window required. | Specimen Type | Typical Detection Window | | --- | --- | | Urine | 1-4 days depending on drug | | Oral Fluid | Up to 48 hours | | Hair | Up to 90 days (non-onsite) | ORDERING ## How do I arrange onsite drug and alcohol testing with AMH Nationwide?
