When is it appropriate for a collector to require an observed collection?

An observed collection is typically required in specific situations where there may be a risk of tampering with the specimen or when the integrity of the drug testing process needs to be safeguarded. In the context of returning to duty after a confirmed positive drug test, the rationale for requiring an observed collection is particularly strong.

When an employee has previously tested positive, the organization must ensure that the subsequent testing process is as tightly controlled as possible to prevent any attempts to cheat or manipulate the results. This step is crucial to maintain the integrity of the testing process and to ensure compliance with regulatory standards.

In contrast, while observed collections might be applicable in reasonable suspicion situations, the requirement is not as universally enforced in those cases compared to the need for strict oversight during a return-to-duty process following a confirmed positive result. Scheduled random and pre-employment collections generally do not necessitate observed procedures unless specific circumstances warrant it. Thus, the requirement for observed collections stems from the need to uphold workplace safety and the reliability of drug testing in sensitive situations.
