Direct observation of urine collection is generally not required; direct observation will be done for which situations?

• A. Random testing
• B. After a positive result
• C. All tests
• D. Reasonable suspicion tests

Answer: (D)

Direct observation is used to protect the integrity of the urine sample when there is a concern that the donor might tamper with it. In most routine collections, privacy is preserved and observation isn’t required. But when there is reasonable suspicion—such as prior tampering, unusual behavior, or other clues that the sample could be substituted or adulterated—the observer watches the collection to ensure the specimen truly comes from the donor and isn’t altered. This is why direct observation is tied to reasonable suspicion tests. Random tests typically aren’t observed to protect privacy, and a positive result leads to a confirmatory lab test rather than an observed collection. Applying observation to all tests would be impractical and overly invasive.
