Which of the following is NOT part of the preparation before specimen collection?

The correct choice highlights a key aspect of the specimen collection process. Preparation before specimen collection involves several critical steps to ensure the integrity and validity of the sample.

One primary focus during preparation is creating a controlled environment for the collection. This includes actions like the inspector examining the specimen for temperature to ensure it is within acceptable limits, and the subject removing outer garments to prevent any potential contamination of the sample. Additionally, the subject selecting a sealed collection kit is an important preparatory step because it helps in maintaining the chain of custody and ensures that the specimen is collected in a clean and uncontaminated manner.

On the other hand, the subject providing a sealed urine sample does not fit into the preparation phase; rather, it is part of the actual collection process after all preparatory measures have been taken. The sealed nature of the sample is significant in ensuring that it remains uncontaminated and securely stored until it is ready for analysis, but it does not constitute a preparatory step.
