What is the purpose of medical surveillance in occupational health programs?

• A. Random annual blood panels for all workers.
• B. Early detection of work-related health effects and monitoring worker health to ensure safety.
• C. Competitive intelligence on employee performance.
• D. Screening for fitness to drive.

Answer: (B)

Medical surveillance is about actively watching workers’ health to catch any work-related effects early and to track health over time so that controls stay effective. It uses targeted medical exams and tests based on the specific hazards in the job (such as hearing tests for high-noise jobs, respiratory tests for inhalation hazards, or skin checks for dermatitis) along with health histories and exposure records. The goal is to detect problems before symptoms appear, take timely actions to protect the worker (like adjusting tasks, improving controls, or providing treatment), and verify that safety measures are working.

Seeing it as random or universal blood panels for all workers isn’t accurate, because testing should be risk-based, ethical, and practical. It isn’t about evaluating employee performance or about fitness to drive unless driving is a core job requirement. The key idea is early detection and ongoing health monitoring to keep workers safe.
