PHMSA Drug Testing: Results Timeline | AMH Nationwide
PHMSA Drug Testing Results Timeline for Timely and Reliable Outcomes
The PHMSA drug testing results timeline typically ranges from 1 to 3 business days after specimen collection. PHMSA drug testing results timeline includes initial screening, confirmation of non-negative results by a certified Medical Review Officer, and possible delays due to lab network routing. Call (877) 731-6362.
What is the typical PHMSA drug testing results timeline?
The typical PHMSA drug testing results timeline from specimen collection to final report is 1 to 3 business days. This timeline applies to federally regulated urine testing conducted under 49 CFR Part 40. The process includes collection at a certified site, initial laboratory screening, and review by a Medical Review Officer (MRO).
How long does the initial PHMSA drug test screening take?
Initial screening is usually completed within 24 to 48 hours after the lab receives the specimen. The specimen is routed through one of five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox. These labs perform immunoassay or equivalent methods to detect the presence of drugs.
What happens if the PHMSA drug test screening is non-negative?
If the initial screen is non-negative, the specimen undergoes confirmatory testing using gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). This confirmation step usually adds 1 to 2 business days to the timeline. Every non-negative result is reviewed by a federally certified Medical Review Officer as part of standard processing.
What factors can delay the PHMSA drug testing results timeline?
Several factors can extend the PHMSA drug testing results timeline beyond the typical 1 to 3 days. Delays may occur due to specimen collection errors requiring recollection, transportation issues between collection site and lab, or increased lab volume. Additionally, complex confirmation tests or requests for additional medical information by the MRO can impact timing.

Which labs process PHMSA drug testing and how does this affect timing?
PHMSA drug testing specimens are routed through five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, and ExperTox. The choice of lab can influence turnaround times slightly based on geographic location and workload, but all adhere to federal guidelines ensuring consistent processing standards.
How is PHMSA drug testing ordered and how are results reported?
AMH provides the lab order and directs the requester to an appropriate collection site; there is no online ordering. After collection, labs handle the testing and reporting. Final results, including MRO-reviewed confirmations, are typically available within 3 business days unless delays occur. Contact AMH by calling (877) 731-6362 for assistance.
