Employers must go beyond lab testing to build effective drug-testing programs. Key components include a written drug-free workplace policy, supervisor and employee training, random testing management, and access to certified labs and medical review officers. Third-party administrators (TPAs) or consortium TPAs (C/TPAs) are essential for managing compliance with federal and state regulations. Choosing a qualified vendor requires checking reviews, certifications, and service capabilities like electronic ordering and result portals. Poor vendor selection can lead to legal exposure and operational failures. A well-managed program protects workplace safety, ensures regulatory compliance, and supports employee well-being.
