CPC Specimen Collection Procedures & Chain of Custody 1 — Questions and Answers
Question 1: What is the first step in a specimen collection procedure?
- Prepare the paperwork
- Verify the donor's identity (Correct answer)
- Seal the specimen cup
- Send the specimen to the lab
Correct answer: Verify the donor's identity
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?
- It tracks donor complaints
- It documents specimen handling and storage (Correct answer)
- It manages billing information
- It records only test results
Correct answer: It documents specimen handling and storage
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?
- Only when touching paperwork
- During the entire collection process (Correct answer)
- Only during sealing
- Only during handwashing
Correct answer: During the entire collection process
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?
- Ignore and proceed
- Document and report immediately (Correct answer)
- Ask the donor to explain
- Continue testing
Correct answer: Document and report immediately
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?
- A regular sticker
- Tamper-evident seal (Correct answer)
- Plastic wrap
- Adhesive tape
Correct answer: Tamper-evident seal
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.
Question 6: How should a specimen be handled after collection?
- Left unattended
- Secured and promptly transferred (Correct answer)
- Discarded after a delay
- Stored without labeling
Correct answer: Secured and promptly transferred
After collection, a specimen must be secured immediately and promptly transferred to ensure its integrity and prevent degradation or tampering. Proper handling involves labeling, sealing, and storing the specimen according to specific guidelines, often including temperature control. This meticulous approach is vital for maintaining the validity of the sample until it reaches the testing laboratory.
Question 7: What information must be included on the Chain of Custody form?
- Only the test type
- Times, signatures, and identification numbers (Correct answer)
- Specimen color only
- Verbal consent
Correct answer: Times, signatures, and identification numbers
The Chain of Custody form must include specific details to maintain a verifiable record of the specimen. This includes precise times of collection and transfers, legible signatures of all individuals handling the specimen, and unique identification numbers for both the donor and the specimen. These details create an auditable trail, ensuring accountability and the integrity of the sample throughout its journey.
Question 8: What must be verified before shipping a specimen?
- Lab operational hours
- Seal integrity and paperwork accuracy (Correct answer)
- The collector's lunch break
- Donor's favorite color
Correct answer: Seal integrity and paperwork accuracy
Before shipping a specimen, it is imperative to verify both the seal integrity and the accuracy of all accompanying paperwork. Checking the tamper-evident seal ensures the sample has not been compromised, while reviewing paperwork confirms correct labeling, donor information, and test requests. These steps are crucial for preventing errors, ensuring the correct tests are performed, and maintaining the Chain of Custody.
Question 9: What role does a certified collector play in Chain of Custody?
- Interpret lab results
- Ensure specimen integrity and documentation (Correct answer)
- Perform medical diagnosis
- Deliver verbal results
Correct answer: Ensure specimen integrity and documentation
A certified collector plays a pivotal role in the Chain of Custody by ensuring the integrity of the specimen and meticulous documentation. They are responsible for correctly identifying the donor, overseeing the collection process, properly sealing and labeling the specimen, and accurately completing all Chain of Custody forms. Their adherence to strict protocols is fundamental to the validity and defensibility of the test results.
