Urine Drug Test: Results Timeline | AMH Nationwide
Urine Drug Test Results Timeline for Accurate and Timely Reporting
The urine drug test results timeline typically ranges from 24 to 72 hours after specimen collection. Non-negative screens undergo confirmation testing, which extends the timeline by several days. Factors such as specimen transport, lab workload, and test panel complexity can delay results. Call (877) 731-6362 for detailed information.
What is the typical timeline for urine drug test results?
The typical urine drug test results timeline is between 24 and 72 hours from the time the specimen is collected at a certified collection site until preliminary results are reported. This timeframe covers initial screening and processing through one of the five national lab networks: Quest Diagnostics, LabCorp, Omega Labs, United States Drug Testing Labs, or ExperTox.
Turnaround time depends on several factors including the type of test panel requested, specimen transport time, and the lab’s current workload.
How long does the initial urine drug screen take?
The initial urine drug screen typically takes 24 to 48 hours after collection to complete. This immunoassay screening identifies the presence of common drugs or their metabolites in urine samples.
Once the sample reaches the lab, analysts perform automated screening procedures and generate preliminary results.
What happens if the urine drug test is non-negative?
If the initial screen is non-negative, the specimen undergoes confirmation testing using more specific techniques such as gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Confirmation testing typically adds 3 to 5 business days to the results timeline. This step ensures accuracy and reduces false positives.
All non-negative results are reviewed by a certified Medical Review Officer (MRO) before final reporting.
What can delay urine drug test results?
Several factors can delay the urine drug test results timeline beyond the typical 24 to 72 hours for initial screening or the 3 to 5 days for confirmation. These include:
Specimen transport delays, especially if the collection site is distant from the lab network.
High lab volume or staffing shortages can extend processing times.
Complex or expanded drug panels requiring additional analyses.
Administrative or chain-of-custody issues requiring clarification.

Contact AMH Nationwide to discuss your specific testing panel and turnaround expectations. Call (877) 731-6362.
Does DOT-regulated urine drug testing affect the timeline?
DOT-regulated urine drug testing follows federally certified urine protocols under 49 CFR Part 40, which can impact the results timeline. The initial screening still takes about 24 to 48 hours, but strict chain-of-custody and specimen handling requirements can add time.
Hair testing is used for non-DOT safety-sensitive roles and has a different timeline not covered here.
How do I get urine drug test results through AMH Nationwide?
AMH Nationwide provides the lab order and directs the requester to an authorized collection site. There is no online ordering or direct specimen submission by individuals.
After collection, specimens are routed to one of the five national lab networks for processing. Call (877) 731-6362 to arrange testing and learn about expected turnaround times.
Common Questions
Initial urine drug test results usually take 24 to 48 hours after specimen collection, depending on the lab’s workload and the test panel complexity.
Confirmation testing for non-negative screens generally adds 3 to 5 business days to the timeline due to more detailed analysis and Medical Review Officer review.
Expedited processing depends on the lab network and test type. Call (877) 731-6362 to inquire about possible options.
Delays can occur due to specimen transport issues, lab workload, complex panels, or chain-of-custody verification requirements.
Yes, all urine drug test results are handled confidentially and reviewed by a certified Medical Review Officer before release.
