CHAIN OF CUSTODY FORM

Chain of Custody in Pre-Employment Drug Screening

Pre-employment drug screening plays a critical role in helping employers maintain safe, compliant, and productive workplaces. Because drug test results can directly influence hiring decisions and a candidate’s professional future, it is essential that the testing process remains accurate, secure, and legally defensible. One of the most trusted methods used by employers and laboratories to ensure reliability is the chain of custody process, a structured system designed to document and track a specimen from collection through final reporting.

The chain of custody procedure establishes a clear and traceable record of everyone who handles the specimen during the testing process. Typically used for urine drug testing, the process begins by verifying the donor’s identity and collecting the specimen under controlled procedures. The sample is then carefully labeled, sealed with tamper-evident materials, and accompanied by a Chain of Custody Form (CCF) that documents each step. This strict documentation ensures that the specimen remains properly identified and protected from contamination, substitution, or tampering throughout the entire process.

Once the specimen is transferred to the laboratory, trained technicians perform the required analysis using certified testing methods. After the laboratory completes testing, a qualified professional—often a Medical Review Officer (MRO)—reviews both the test results and the accompanying documentation before the results are finalized. By limiting the number of individuals involved and maintaining detailed records at every stage, the chain of custody system provides the highest level of validity, ensuring drug test results are accurate, defensible, and compliant with industry standards.
