How long does an employee have to report for drug screen testing?

• A. 30 minutes
• B. Two hours
• C. One hour
• D. Three hours

Answer: (C)

Prompt reporting after notification is crucial in drug screening to preserve test integrity and maintain the chain of custody. Reporting within one hour helps ensure the test reflects the employee's current status, reduces the opportunity to tamper with a sample, and keeps the collection process on schedule for documentation and verification. If reporting is delayed beyond this short window, it can be treated as a refusal or noncompliance, which carries serious consequences similar to testing positive. Longer windows like thirty minutes might not be feasible in practice, and two or three hours significantly increase the risk of tampering, scheduling conflicts, and questions about the test's validity, making them less suitable.
