What is the first step a collector should take when conducting a drug test?

The first step a collector should take when conducting a drug test involves ensuring that the testing environment is controlled and that the subject is prepared for the collection process. Observing the subject wash their hands is a vital step because it helps prevent any contamination of the sample. This action promotes hygiene and assures the integrity of the sample collected, which is essential for the accuracy and reliability of the test results.

Initiating the process with this observation sets a standard for proper procedure and helps to build trust between the collector and the subject. It also reflects adherence to best practices in the collection process, which is crucial in maintaining the validity of the drug testing process.

Other steps are important but come after this initial observation as they pertain to documenting the collection, handling the samples, or performing specific tests, which are contingent on having a trustworthy and uncontaminated sample to begin with.
