Occupational health laboratory tests for workers assess exposure to hazardous substances and monitor overall health to prevent workplace-related illnesses. Common tests include blood lead levels, pulmonary function tests for respiratory exposure, and assessments for chemical exposure such as solvents or heavy metals. These tests help identify health risks, ensure compliance with safety regulations, and promote the well-being of employees by facilitating early detection of potential health issues linked to their work environment. Regular monitoring helps employers create safer workplaces and implement appropriate health interventions.
