What does a missing "split" specimen box indicate in a CCF?

When a "split" specimen box is missing in a Chain of Custody form (CCF), it indicates that the collection process may not meet the required standards for validity. The split specimen is crucial in drug testing as it provides a backup sample that can be tested if there are issues with the primary sample. This backup allows for a second opinion and can be especially important in cases where the initial test results are questioned or if the specimen needs to be retested.

The absence of the split specimen box raises concerns about the integrity and reliability of the test results. It suggests that the testing process has not adhered to established protocols, which could compromise the outcome. Therefore, the correct understanding is that the test may not be considered valid due to this missing component, emphasizing the importance of thoroughness in the collection and documentation stages of the testing process.
