CPC Specimen Collection Procedures & Chain of Custody

Question 1

What is the first step in a specimen collection procedure?

Accepted Answer

Verify the donor's identity

Answer

Verifying the donor's identity is the critical first step in any specimen collection procedure. This ensures that the correct individual is providing the specimen and prevents misidentification, which could lead to serious errors in testing and reporting. Proper identification is fundamental to maintaining the integrity and accuracy of the entire collection process.

Question 2

Why is the Chain of Custody form important?

Accepted Answer

It documents specimen handling and storage

Answer

The Chain of Custody (COC) form is essential because it provides a meticulous, unbroken record of everyone who handled the specimen from collection to testing. This documentation ensures the integrity and security of the sample, proving that it has not been tampered with or substituted. It is a legal document critical for maintaining the validity of test results, especially in forensic or workplace drug testing.

Question 3

When should a collector wear gloves during collection?

Accepted Answer

During the entire collection process

Answer

A collector must wear gloves during the entire collection process to maintain hygiene and prevent contamination. This protects both the collector from potential exposure to biohazards and the specimen from external contaminants. Adhering to universal precautions ensures the safety of all involved and the integrity of the sample.

Question 4

What should be done if a specimen is tampered with?

Accepted Answer

Document and report immediately

Answer

If a specimen is suspected of being tampered with, it is crucial to document the observation immediately and report it according to established protocols. Ignoring it or proceeding without proper documentation compromises the integrity of the test and could invalidate the results. Prompt reporting ensures that appropriate actions can be taken, such as re-collection or investigation.

Question 5

What is considered a secure specimen seal?

Accepted Answer

Tamper-evident seal

Answer

A tamper-evident seal is considered a secure specimen seal because it visibly indicates if the specimen container has been opened or altered after sealing. This type of seal provides a clear visual cue of any unauthorized access, preserving the integrity of the sample. It is a critical component of the Chain of Custody, ensuring the reliability of the test results.
