Chain of custody testing
Scrupulous care to document legality
At Mayo Clinic Laboratories, chain of custody drug testing is performed under controlled conditions at our CLIA-certified Clinical and Forensic Toxicology Laboratory in Rochester, Minnesota. We offer the chain of custody process documentation for many of our clinical drug tests. Per regulatory requirements, all chain of custody urine samples submitted receive adulterant testing and confirmation of all presumptive positive screening results.
More information
Our laboratory experts adhere to the highest quality standards to ensure chain of custody drug test results are documented correctly, providing clients the confidence to support forensic patient care.
The chain of custody documentation process provides:
- Clear and unique identification of the subject being tested.
- Clear and unique labeling of the specimen.
- Identification of all persons who handle the specimen — legible signature required.
- A historical record of events, with action dates clearly stated.
- Security of the specimen using a sealed, tamper-evident process.
Please note, Mayo Clinic Laboratories does not perform workplace drug testing. Any specimens submitted for workplace drug testing purposes will be canceled immediately.

Highlights
Loralie Langman, Ph.D., explains the difference between chain of custody and clinical toxicology testing. Chain of custody is a process used for toxicology testing when the results might have legal implications for the individual tested. Clinical toxicology testing is used for routine medical care. Mayo Clinic Laboratories offers a full range of clinical and forensic toxicology testing.
