The PHMSA drug testing collection process is a federally mandated procedure designed to ensure accurate and legally defensible drug test results for safety-sensitive transportation employees. It follows strict chain of custody protocols and requires identity verification, specimen collection, and secure handling. This process complies with the Department of Transportation and PHMSA regulations, using a federally certified [urine](https://amhnationwide.com/urine-drug-testing/) collection protocol under [49 CFR Part 40](https://www.transportation.gov/odapc/part40). IDENTIFICATION ## What identification is required for PHMSA drug testing collection? Donors must present valid, government-issued photo identification at the collection site. This is to confirm the identity of the individual providing the sample and prevent substitution or tampering. Acceptable IDs include a driver’s license, passport, or military ID. The collector verifies the ID against the donor’s personal information before proceeding. SPECIMEN COLLECTION ## How is the urine sample collected during PHMSA drug testing? The urine specimen is collected under strict chain of custody procedures to maintain integrity and security. The donor provides the sample in a private area monitored by a same-gender collector as required by regulations. The collector observes the sample collection discreetly to ensure the specimen is not adulterated or substituted. The sample volume and temperature are immediately checked to confirm validity. Collection uses a federally certified urine protocol under 49 CFR Part 40 Same-gender collector observes sample provision Specimen temperature verified within 4 to 38 degrees Celsius Sample sealed and labeled with unique chain of custody form CHAIN OF CUSTODY ## What happens to the sample after collection in PHMSA testing? After collection, the urine sample is sealed and labeled with a chain of custody form that tracks every person who handles the specimen. This ensures the sample’s security from collection to laboratory testing. AMH Nationwide routes all PHMSA drug testing samples to one of five national lab networks: [Quest Diagnostics](https://www.questdiagnostics.com/), [LabCorp](https://www.labcorp.com/), Omega Labs, United States Drug Testing Labs, or ExperTox.
