Which elements adhere to protocols in drug testing to ensure specimen integrity and custody?

• A. QC, chain of custody, and secure specimen integrity
• B. Documentation, patient consent, and data privacy
• C. Equipment calibration, sample labeling, and storage temperature
• D. Internal audits, staff training, and incident reports

Answer: (A)

In drug testing, keeping a specimen trustworthy from collection to disposal hinges on tracking the sample and ensuring it isn’t altered. Quality control ensures the testing process itself is accurate and reliable, while a documented chain of custody records every person who handles the specimen, when, and why, preventing tampering or mix-ups. Secure specimen integrity covers safeguards like tamper-evident containers and proper storage conditions to maintain the sample’s condition throughout the process. Together, these elements directly protect both the integrity and the custody of the specimen. Other options touch on important lab practices but don’t directly address the combined need for custody and integrity. Documentation, patient consent, and data privacy focus on handling information rather than the physical specimen’s custody. Equipment calibration, sample labeling, and storage temperature are important for accuracy and proper handling, but they don’t by themselves establish the custody trail. Internal audits, staff training, and incident reports support overall quality systems, but they’re broader QA activities rather than the specific protocols that guarantee specimen custody and integrity.
