Urine Drug Test: How It Works | AMH Nationwide
Understanding Urine Drug Test How It Works for Reliable Results
Urine drug test how it works involves collecting a urine sample under controlled conditions, analyzing it through initial screening and confirmatory testing at certified labs, and reviewing non-negative results by a Medical Review Officer. This process ensures accurate detection of substances. Call (877) 731-6362 to arrange testing.
How is the urine sample collected for the drug test?
The urine sample for a drug test is collected under supervised conditions at an authorized collection site. AMH Nationwide directs the requester to one of five national lab networks including Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. The collector ensures the sample is obtained in a secure, sanitary manner to prevent tampering or substitution.
Where is the urine sample sent for analysis?
After collection, the urine sample is sent to one of the five national lab networks used by AMH for analysis. These labs follow strict protocols for handling, processing, and testing the specimens. The sample chain of custody is maintained from collection through delivery to the lab to ensure integrity.
What happens during the initial screening of the urine drug test?
The initial screening test uses immunoassay techniques to detect the presence of specific drug metabolites in the urine. This step is designed to quickly identify samples that may contain substances of abuse. A negative screen means no further testing is required, while a non-negative screen triggers confirmatory testing.
How does confirmatory testing work in the urine drug test process?
Confirmatory testing is performed on any urine sample that screens non-negative. It uses more precise methods such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS) to definitively identify and quantify drug metabolites. This step eliminates false positives from the initial screen.

What role does the Medical Review Officer (MRO) play in the urine drug test process?
Every non-negative urine drug test result undergoes review by a certified Medical Review Officer. The MRO evaluates the lab findings alongside any medical explanations provided by the individual tested to determine if legitimate reasons exist for the presence of certain substances. Only then is a final result reported to the requester.
How does urine drug test how it works differ for DOT-regulated testing?
For DOT-regulated safety-sensitive positions, urine drug testing follows the federally certified urine protocol under 49 CFR Part 40. This protocol includes strict chain of custody, specimen integrity checks, and specific collection procedures. Hair testing is not used for DOT roles; urine remains the standard specimen.
Common Questions
No, AMH directs all urine drug test collections to authorized collection sites within the national lab networks. This ensures proper supervision, chain of custody, and sample integrity.
Turnaround times vary by lab and panel but typically range from 24 to 72 hours after the sample reaches the lab. The MRO review may add additional time for non-negative results.
Urine drug tests can detect a variety of substances including opioids, cocaine, amphetamines, cannabinoids, benzodiazepines, and others depending on the specific panel requested.
Yes, hair testing uses a different specimen and is generally reserved for non-DOT roles. Urine drug tests follow specific protocols that differ from hair analysis.
A certified Medical Review Officer reviews all non-negative results to verify medical explanations and confirm the final interpretation before reporting.
No, AMH does not provide kits for self-collection or online ordering. Testing is coordinated through lab networks and collection sites. Contact AMH to schedule your test.
