Scenario 5:

The collector noticed that the urine the donor had just handed to her had a very strong smell like that of a cleaning product, such as bleach.

Collector's Response:

The collector completed the collection in the usual manner, and then explained to the donor that, because of the strong, unusual smell, the first specimen was suspected for adulteration. The collector then told the donor that an observed collection would now be done. Both the "suspect" specimen and the specimen collected by direct observation are sent to the laboratory for testing.

Besides an unusual smell, other indications of adulteration might be an unusual color that cannot be explained my medication, particles, or debris in the urine, and a heavy or thick foam that is inconsistent with urine.
