For random drug testing, when must employees present themselves at the designated facility?

• A. Within 24 hours
• B. Immediately
• C. Within 2 hours
• D. Within 48 hours

Answer: (B)

The essential idea is that random drug testing should be carried out with immediate reporting to preserve the integrity of the process. When an employee is notified, presenting themselves to the designated collection facility right away helps ensure the sample’s validity, prevents any possible tampering, and maintains the proper chain of custody. Delays such as waiting 24, 48 hours, or even a few hours could create opportunities to alter circumstances or miss the collection window, which undermines the test’s reliability. Therefore, answering with immediate reporting best reflects how these procedures are designed to work in practice.
