In the specimen collection process, what is the purpose of the collector having the subject empty their pockets?

The purpose of having the subject empty their pockets during the specimen collection process is primarily to prevent any tampering during collection. This step is essential to ensure that the integrity of the specimen is maintained and that no unauthorized substances or materials can be introduced or concealed prior to the collection. By requiring the subject to empty their pockets, collectors can minimize the risk of the subject having access to materials that could compromise the test's accuracy, such as masking agents or other substances that may interfere with the results.

This practice helps to uphold the standards of testing procedures, ensuring that the results reflect the true state of the subject's condition without the influence of external factors. It is a critical part of the protocol designed to maintain the integrity and reliability of drug testing processes.
