Which labeling step is CRITICAL for chain of custody integrity on a urine drug specimen?

The donor must initial the specimen label in the collector's presence to establish witnessed chain of custody and confirm the specimen belongs to them.
What action is required if a collector observes a donor attempting to add a foreign substance to a urine specimen?
Answer: Discard the specimen, document the refusal, and notify the employer/MRO

When must a collector perform a direct-observation collection for a return-to-duty or follow-up federal drug test?
Answer: Always, for every return-to-duty and follow-up test
DOT regulations mandate that all return-to-duty and follow-up tests must be conducted under direct observation, with no exceptions.
For a federal workplace urine drug test, what must the collector do if the specimen temperature falls outside the 90–100°F range?
Answer: Accept the specimen but note the temperature discrepancy and offer a second collection under direct observation
An out-of-range temperature is documented on the CCF as a 'temperature outside range' remark, and the collector must offer an immediate second collection under direct observation.
What is the purpose of bluing agent (dye) placed in toilet water during a urine drug test collection?
Answer: To deter dilution of the specimen with toilet water
Blue dye is added to toilet water so that if a donor uses it to dilute or substitute their specimen, the blue color will be detected, indicating tampering.
A donor arrives for a pre-employment urine collection without a photo ID. What is the correct collector action?
Answer: Allow an employer representative to vouch for the donor's identity
If a donor lacks a photo ID, federal guidelines allow an employer representative to positively identify the donor in lieu of a photo ID.
What is the correct procedure for sealing and securing a urine specimen bottle after collection?
Answer: Apply the tamper-evident label across the bottle cap in the donor's presence before the donor initials it
The tamper-evident label must be applied over the cap while the donor watches, and then the donor initials the label to establish witnessed, unbroken chain of custody.
