Mayo Clinic Laboratories does not perform workplace drug testing. In other circumstances where the test results could be challenged in a court of law, a chain of custody process should be utilized.
Failure to complete the collection process correctly, including labeling of the sample, as well as all details of the accompanying documentation, may result in the inability to process the sample.
A convenient kit is available to facilitate the chain-of-custody process.
