Pulmonary Function Testing


Pulmonary Function Tests (PFT’s) consist of several tests designed to give the pulmonologist information about lung function and help to determine the extent of any pulmonary disease.

These tests identify patients who might have obstructive or restrictive lung disease. They also help to determine the severity of the diseases and provide a baseline for future comparison if the patient shows improvement or deterioration.

Our PFT lab is equipped with state-of-the-art equipment and all tests are administered by a Certified PFT Professional.
