What are the required proficiency demonstrations (mock collections) for DOT oral fluid drug testing?

For each of the five mock collections, the collector must check the expiration date of the device, show it to the employee, and record the date on the CCF used. The collector must ensure, when applying the labels, they do not cover the expiration dates.

The five mock collections for each collection device must include one insufficient specimen quantity scenario, one scenario in which the employee has something in their mouth that might interfere with the collection; one scenario in which the employee attempts to tamper with the specimen; and one scenario in which the employee refuses to sign the CCF and one uneventful collection scenario.
