What happens when a collector suspects that a donor has provided an adulterated sample?

When a collector suspects that a donor has provided an adulterated sample, the appropriate course of action is to follow established protocol for a retest. This is crucial to ensure the integrity of the testing process and to confirm whether the sample is indeed adulterated.

Protocols typically outline specific procedures to address any concerns about the validity of a sample, which can include retesting the donor with a new sample that is collected under supervised conditions. This helps to ensure a fair and accurate testing process. Adhering to protocol not only helps in maintaining the integrity of the testing system but also ensures that the rights of the donor are protected during the investigation of the potential adulteration.

Other choices do not align with best practices. Ignoring suspicions undermines the reliability of drug testing, while proceeding with the test as normal could lead to erroneous results going unchecked. Calling the authorities immediately would be excessive and could disrupt the standard procedure, as the matter should first be handled internally according to established guidelines before escalating it. Following the correct testing protocol is essential to uphold the validity of the drug testing process.
