Spirometry lung function testing is a screening test used in occupational health to determine a worker's lung function status. Spirometric testing is also a diagnostic tool which shows the rate of air flow and the volume of air moved through the lungs to identify individuals with obstructive or restrictive disease. Spirometry will detect the most common lung disease (COPD) more than ten years before symptoms occur. 

In occupational health, spirometry is commonly used to assess pulmonary status including the dectection of abnormalities in lung function. Spirometric testing is administered in combination with a nurse medical to ensure a worker is free from restrictive disease therefore ensuring the worker has adaquate lung function and is able to wear a respirator if required.
