Pulmonary Laboratory

The pulmonary laboratory at UT Southwestern Medical Center combines state-of-the-art testing techniques with a caring staff of lung specialists who are dedicated to helping you achieve the best possible outcome for your lung condition. 

Evaluation

Our lung specialists use our pulmonary laboratory to precisely determine the nature of a patient’s lung disease, assess its severity, and provide the treatments needed for improved health.

The laboratory is available for inpatient and outpatient examinations, and includes comprehensive tests for lung capacity, gas exchange and analysis, stress testing, and blood-flow analysis. Our pulmonologists collaborate with laboratory staff to provide brachytherapy and interventional procedures, including rigid bronchoscopy, stent placement, and thoracoscopy.
