Navigating Return to Duty and Follow-Up Drug or Alcohol Testing: Ensuring Compliance and Safety


In the realm of workplace drug and alcohol testing, two essential types of tests are often required: Return to Duty Testing and Follow-Up Testing. Understanding the distinctions between these tests is crucial for maintaining compliance with regulations and ensuring a safe working environment. In this blog post, we will explore the differences between Return to Duty Testing and Follow-Up Testing, shedding light on their significance in substance abuse programs and employment protocols.


A Return to Duty Test is NOT a test for an employee that has been laid off or was absent for an extended period of time due to illness or injury. In the instance of returning from an illness or injury, a pre-employment test would be completed prior to said employee returning to any safety sensitive position.


Rather Return to Duty Testing is performed when an employee has tested positive for drug and/or alcohol test or had a refusal to test. Typically when this occurs, the employee is required to complete a substance abuse program in accordance with the regulatory requirements. This Return to Duty test serves as the first test conducted after completing the rehabilitation program and returning to work. It can also be used as a pre-employment test if the individual who has completed a substance abuse program is testing for a new job. Return to Duty Testing is observed, requiring a collector of the same gender to be present. Passing the Return to Duty Test is a crucial step for employees to resume their duties. Subsequent tests conducted thereafter are considered Follow-Up Testing. In many cases, companies may require employees to bear the costs associated with participating in substance abuse programs and its subsequent testing.


Follow-Up Testing is conducted when an employee has previously tested positive for drugs or alcohol and has completed a Return to Duty test, following the completion of a substance abuse program. These tests are conducted under direct observation, meaning a collector of the same gender must observe the employee while they provide a urine sample. The frequency and number of follow-up tests are determined by a Substance Abuse Professional (SAP) as part of the individual's rehabilitation process. According to DOT regulations, a minimum of six tests must be conducted within a 12-month period. However, the SAP has the discretion to extend the testing period and/or require additional tests. It's important to note that an employee undergoing Follow-Up Testing remains in the random drug and alcohol testing pool and can be selected for such testing at any time. Random testing selections are completed in addition to follow-up testing, not in place of a follow-up test.


Understanding the nuances between Follow-Up Testing and Return to Duty Testing is crucial for maintaining compliance and ensuring a safe workplace environment. Employers must establish clear policies regarding substance abuse programs, testing procedures, and employee responsibilities. By adhering to these protocols, organizations can uphold their commitment to employee well-being and regulatory compliance.
