From the DOT Publication Best Practices for Random Drug and Alcohol Testing.
It is the best practice for an employer to document everything on the entire random testing process. This includes the numbers, names drawn, dates and times of notification, dates and times of collections, why a selected employee was not tested during a selection cycle, etc. If you’re not sure, document it!
Best Practices:
- Service agents and C/TPAs providing random selection and testing services to employers should monitor on an ongoing basis (daily or weekly) the random tests that have been completed and compare them to those that were selected. If a random test has not been completed in an acceptable timeframe (within a day or week) of the expected test date, the service agent or C/TPA should contact the employer to determine the status of the test and take the necessary steps to ensure the test is completed within the selection period.
- Employers, service agents, and C/TPA should not wait until the end of the selection period to reconcile the random testing numbers. This is a weak business practice that we want to discourage. Remember: You must maintain all your testing records in accordance with industry specific regulations.
