Toxicology and Drug Testing Specimen Transport
Drug testing transport must preserve specimen identity, required seals and custody documentation. Clinical testing, DOT testing and forensic testing do not use one interchangeable workflow.

Quick answer
Drug testing transport must preserve specimen identity, required seals and custody documentation. Clinical testing, DOT testing and forensic testing do not use one interchangeable workflow.
Identify which testing program applies
A specimen collected for clinical toxicology may have different requirements from a federally regulated workplace test or a forensic investigation. Ask the ordering organization and receiving laboratory to identify the governing program, forms and shipment instructions before collection begins.
For DOT testing, use the current Part 40 requirements and collection guidance. Do not apply a federal custody form to every private clinical test by assumption, or substitute ordinary delivery records for the program's required documentation.
Preserve the collector's work
The collector is responsible for the collection steps, specimen preparation, seals and forms required by the applicable program. A courier should receive the prepared shipment and maintain its condition. Drivers should not reopen bottles, replace seals or attempt to correct an irregular collection record.
Reconcile the external shipment identifier and destination.
Check for visible package damage without disturbing protected contents.
Follow the laboratory's packaging and temperature instructions.
Keep required documents protected and associated with the shipment.
Report missing information or suspected tampering promptly.
Understand what custody evidence means
A transport scan can demonstrate that a package changed hands, but it does not replace the collection and laboratory custody record. Equally, not every program requires every commercial carrier employee to sign the collection form. Follow the actual program rules rather than inventing an extra signature step that conflicts with them.
Record the courier's operational handoffs and exceptions in a way that can be reconciled with the specimen shipment. Restrict access to sensitive testing information and avoid unnecessary details in dispatch messages or delivery photographs.
Escalate delays and irregularities
If a seal appears damaged, the package leaks or the receiver cannot match the shipment, preserve the condition and contact the authorized program representative. The laboratory, medical review officer or other designated authority determines the consequence under the applicable testing process.
Do not promise that a result will remain legally defensible solely because the courier has a tracking history. Collection quality, analytical procedures, program compliance and legal requirements also matter. Review missed pickups and receiving cutoffs before repeated delays affect the testing program.
Agree on the complete lane
Confirm who supplies packaging, the authorized laboratory address, holiday arrangements and the process for an unsuccessful delivery. Return shipments and retained specimens should follow a separately approved instruction rather than an improvised reverse route.
Plan your next step
Explore OnWay's medical courier services or request a delivery quote. Share the material, route, handling requirements and receiving hours so the team can assess service suitability. Specialized or regulated shipments require confirmation of capabilities before acceptance.

- Identify the testing program first.
- Do not disturb specimen seals or correct collector records.
- Delivery scans supplement rather than replace required custody records.
Frequently Asked Questions
Does every drug test use a Federal Custody and Control Form?
No. The appropriate form depends on the testing program. DOT and other regulated programs have specific requirements that should not be generalized to all clinical testing.
Can the courier reseal a damaged specimen bottle?
No. Preserve the condition and contact the authorized collector, laboratory or program representative for instructions.
