Professional chain-of-custody support for specimen collection, transfer, and documentation.
Xorevion Diagnostics provides chain-of-custody support for drug testing, DOT collection support, DNA specimen collection, employer testing programs, mobile collection services, and medical courier coordination.
Specimen handling is only as strong as the documentation behind it.
Chain of custody is the documented record of how a specimen is collected, identified, sealed, transferred, received, and handled. It helps protect specimen integrity, supports proper documentation, and creates a clearer handling history from collection to delivery.
A clear record of collection, handling, transfer, and receipt.
Specimen Identification
Chain-of-custody support begins with accurate donor, participant, or specimen identification when required by the testing process.
Collection Documentation
Forms, labels, signatures, dates, collection details, and required instructions help create a clear record of the collection event.
Secure Transfer
After collection, specimens or documents may require secure packaging, transfer documentation, and courier coordination.
Chain of custody helps protect the credibility of the collection process.
In drug testing, DOT collection support, DNA collection, employer testing, and legal-sensitive situations, the way a specimen is collected and handled can matter as much as the specimen itself. If documentation is incomplete, if labeling is unclear, or if transfer details are missing, the process can become confusing and difficult to verify.
Xorevion’s chain-of-custody support is designed to help create an organized record of the collection process. This may include confirming paperwork, checking identification when required, collecting the specimen, sealing and labeling the specimen, documenting transfer details, and coordinating courier delivery when applicable.
- Donor or participant identification support when required
- Collection paperwork review and documentation support
- Specimen labeling and seal verification
- Transfer documentation awareness
- Courier coordination when applicable
- Professional handling from collection to destination
Employers rely on chain of custody to keep testing organized.
Employer testing programs often require clear documentation. Whether a company is coordinating pre-employment drug testing, random testing, reasonable suspicion collection, post-incident testing, return-to-duty collection, or DOT collection support, the employer needs confidence that the collection was handled properly.
Chain of custody helps employers maintain a more organized testing process by creating a documented pathway between the donor, collector, specimen, paperwork, courier, and receiving destination.
- Pre-employment testing documentation
- Random testing collection support
- Post-incident collection documentation
- Reasonable suspicion collection support
- Return-to-duty and follow-up documentation
- Employer-authorized transfer coordination

Xorevion can support DOT collection handling when the proper authorization, forms, and requirements are provided.

DNA collections may require documented identity and handling.
Some DNA collections are for personal knowledge only, while others may require legal chain-of-custody documentation.

Legal acceptance depends on the outside laboratory, court, agency, attorney, institution, or requesting party. Xorevion supports professional DNA specimen collection and documentation handling based on the instructions provided.

- Legal-sensitive collection handling
