What Is A Drug Test Chain-Of-Custody form


Commonly referred to as a COC or CCF form.

Chain of Custody refers to the formal documentation of custody, transfer, control, analysis and disposition of a specimen submitted for a drug screen or drug test. 

Specimen Integrity

Both laboratory and instant drug testing needs to incorporate a COC to insure the integrity of the specimen to be tested and the process.

As the specimen is processed, information is added on the COC form as the specimen is handled or processed by each person.

As the chain of custody form is a legal document and can be invalidated if the the specimen has been tampered with or lacks the complete information on it.

Federal Workplace Drug Testing Programs published by the Substance Abuse and Mental Health Services Administration (SAMHSA) provides guidelines and standards to be used in the drug testing process. .

Electronic Chain Of Custody and Control Forms

Electronic Chain-of-Custody and Control Forms (eCCF) are the digital versions of the paper COC Custody and Control Form documents used for drug test ordering, specimen collection processing, and chain of custody documentation for workplace drug testing.

The CCF documents the external specimen chain of custody — i.e., the handling of the drug test specimen from the time it is collected until it is received at the laboratory.


All drug test results including the COC form are to be treated as confidential and private.
