Scenario 2:
The donor was asked to remove his hat before going into the restroom. As he reluctantly did so, it was noticed that he was trying to conceal a container that was hidden inside the hat.
Collector's response:
The collector first explains the circumstances to a supervisor. If the supervisor concurs that an observed collection should be done, the collector then tells the donor that a directly observed collection will be conducted because his conduct indicated a possible attempt to adulterate, substitute, or dilute the specimen. The collector marks on the CCF that the collection was observed and notes under Remarks why it was observed.
