What issue is indicated by missing information in Line G of the CCF?

Missing information in Line G of the Chain of Custody Form (CCF) signifies a fatal flaw. This particular line is critical because it contains essential information that must be complete and accurate for the sample to be deemed valid. A fatal flaw renders the sample invalid and necessitates that a new sample collection must be performed. This is due to the strict regulatory requirements surrounding the integrity and reliability of drug testing processes, where any missing or incorrect information can compromise the validity of the test results.

Other types of issues such as correctable flaws or administrative flaws may result in the need for correction but do not invalidate the sample immediately. Formatting errors, while potentially problematic, typically do not impact the overall validity to the same extent as a fatal flaw does. Consequently, identifying a missing entry as a fatal flaw emphasizes the importance of attention to detail in the drug testing process, ensuring all necessary information is recorded accurately to maintain the integrity of the testing protocol.
