Special Collections - Ccma

Which urine drug test collection step helps reduce substitution or adulteration risk?

Use controlled access and follow observed collection policy. Limits opportunities for tampering by monitoring the process and restricting access.
Which storage practice is required when a COC specimen is awaiting courier pickup?

Secure, access-controlled storage with documented custody. Prevents unauthorized access and maintains documented control to uphold chain of custody.
Identify the required number of patient identifiers to label a specimen in clinical practice.

At least two patient identifiers. Standard protocol reduces identification errors and enhances patient safety in specimen processing.
What is the correct action if a urine specimen temperature is out of the acceptable range per policy?

Treat as a discrepancy and follow recollection/escalation policy. Suggests possible adulteration or substitution, necessitating protocol for retesting to ensure validity.
Which item is required on a chain-of-custody form to link the specimen to the correct patient?

Unique donor or specimen identification number. Provides a traceable link between the donor and specimen for verification throughout the custody chain.
Which action is required when collecting a timed urine specimen such as a $24$ -hour urine?

Record start/stop times and keep the collection refrigerated as required. Ensures accurate quantification of analytes over the specified period while preserving specimen quality.
What is the correct action if a tamper-evident seal is broken or missing on a COC specimen?

Reject and recollect per policy; document the discrepancy. Indicates potential tampering, requiring rejection to preserve evidence integrity and legal standards.
Which on-site check is commonly performed for urine drug testing to assess specimen validity?

Measure temperature within the required time window. Confirms the specimen is freshly voided and not substituted, as temperature falls outside body range if adulterated.
What is the correct response if a COC specimen is left unattended in an unsecured area?

Document breach and notify supervisor; specimen may be invalid. Indicates a break in protocol, potentially compromising integrity and requiring invalidation.
What is the correct patient instruction for a clean-catch midstream urine specimen?

Cleanse, start voiding, then collect midstream without touching inside. Reduces contamination from external sources, ensuring a representative sample for analysis.
Which special collection requires discarding an initial portion of urine before collecting the specimen?

Clean-catch midstream urine collection. Flushes contaminants from the urethra to obtain a more accurate midstream sample for testing.
What must you do first when a patient arrives for a chain-of-custody drug test collection?

Verify patient identity using acceptable identification. Confirms the correct individual to prevent identity fraud and ensure specimen accuracy.
What is the correct timing for labeling a specimen container during special collections?

Immediately after collection, in the presence of the patient. Prevents mix-ups and confirms patient verification to uphold accuracy and chain of custody.
Which term describes documented specimen control from collection through final disposal?

Chain of custody. Refers to the process ensuring continuous documentation of specimen handling to maintain integrity and prevent tampering.
What must be recorded for each custody transfer on a chain-of-custody form?

Date/time, names/signatures, and purpose of transfer. Ensures a complete audit trail for accountability and verification of specimen handling.
What is the primary purpose of chain of custody documentation for a specimen?

To ensure specimen integrity and legal defensibility. Maintains an unbroken record of handling to prevent tampering and support admissibility in legal proceedings.
What is the correct first void handling for a timed $24$ -hour urine collection?

Discard the first void, then collect all urine until end time. Establishes the collection start point, allowing all subsequent urine to represent the full timed interval.
Which specimens most commonly require strict chain of custody procedures in outpatient care?

Forensic and drug testing specimens. These require rigorous tracking due to their legal implications in evidence or employment screening.
What is the correct handling for a specimen that must be protected from light (for example, bilirubin)?

Wrap in foil or use an amber container immediately. Prevents photodegradation of light-sensitive analytes to maintain specimen stability and accuracy.
Identify the correct action if information on the specimen label and requisition/COC form does not match.

Do not send; resolve and correct per policy before transport. Prevents processing errors or legal issues by ensuring all documentation aligns before proceeding.
Which two identifiers are appropriate for specimen labeling at the bedside or collection site?

Full name and date of birth. These are reliable, verifiable details that minimize mislabeling risks during collection.
Which specimen collection requires a sterile container and strict avoidance of contamination?

Urine culture specimen. Prevents bacterial contamination that could skew results in microbiological testing.
Which action best maintains chain of custody immediately after sealing a specimen container?

Document the seal and collector signature on the COC form. Records the sealing process to establish accountability and deter tampering in the custody chain.
Which condition requires documenting every transfer of a specimen between individuals?

Any chain-of-custody specimen handling. Requires full documentation of transfers to track possession and prevent unauthorized access.
What is the correct action if the donor cannot provide acceptable identification for a COC test?

Do not collect; follow site policy and notify the requester. Prevents unauthorized collection and maintains protocol integrity by escalating to appropriate parties.
