Pulmonary Function Testing

Pulmonary Function Test (PFT)

Pulmonary function tests (PFTs) may be ordered as part of routine health assessment, screening for those with workplace exposures, diagnostic assessment for those with suspected lung disease, or management of those with chronic lung disease over time.  

Covid-19 Notice:  All patients are required to be fully vaccinated (present proof) or have a negative COVID-19 test result within 72 hours of their pulmonary function test appointment.

  • Patients should first call to schedule their PFT.
  • Once a PFT appointment has been made, patients can call 443-997-9537  to have a COVID-19 test scheduled at a Hopkins location.

Routine PFT’s include:

  • Spirometry: Measures the flow of air with forced expiration and may be repeated after a bronchodilator inhaler is given.
  • Lung volumes: Measures the volume of air in the lungs at different levels of inspiration and expiration.
  • Diffusing capacity: Measures the ability of the lungs to transfer gases, such as oxygen and carbon dioxide.

About our Laboratory

Pulmonary Function Testing Team

The Johns Hopkins Pulmonary Function Laboratories have a tradition of excellence with a history that dates back to the early 1940s. Early leaders in the field of pulmonary physiology from Johns Hopkins described the principles of airflow limitation and developed early techniques to measure oxygen tension in arterial blood. Today, we perform over 30,000 pulmonary function tests each year at several locations for patients from our local community and those that travel from other states and countries.
