90. Which of the following information should be included in the chain of custody following a blood alcohol testing procedure?
Answer: B
The identity of each person who handles the specimen should be included in the chain of custody following a blood alcohol testing procedure.
Including the identity of each person who handles the specimen is essential for maintaining the integrity of the chain of custody. This ensures that the specimen can be traced and verifies that it has been handled appropriately throughout the testing process.
A) The timeline of the individual prior to specimen collection
While the timeline of the individual may provide context for the test results, it is not a critical component of the chain of custody. The chain of custody primarily focuses on the handling and transfer of the specimen itself, rather than the individual's actions leading up to the collection.
B) The identity of each person who handles the specimen
This is the correct choice as it establishes accountability and traceability for the handling of the specimen. Documenting who has access to the specimen helps prevent contamination or tampering, ensuring the reliability of the test results.
C) The physical and mental status of the individual before and after specimen collection
Although the physical and mental state of the individual may be relevant to the interpretation of the test results, it does not pertain to the chain of custody. The chain of custody is focused on the specimen's management rather than the individual's condition.
D) The condition of the specimen every hour
Monitoring the condition of the specimen every hour is impractical and not a standard requirement for the chain of custody. While the specimen's integrity is important, the focus should be on documenting its handling rather than continuous monitoring.
Conclusion
The identity of each person who handles the specimen is crucial for ensuring the chain of custody is maintained properly, which is vital for the validity of blood alcohol testing. Other options, while potentially relevant to the overall testing process, do not fulfill the specific requirements of establishing a trustworthy chain of custody. Thus, Option B is the only choice that directly addresses the procedural necessity in question.
