Understand your breathing and sleep health with pulmonary function testing and sleep studies. These diagnostic services can help clinicians assess respiratory symptoms and guide further evaluation when clinically appropriate.
Explore our two key respiratory diagnostic categories. The appropriate test depends on your symptoms, medical history and clinician's recommendation.
Pulmonary function tests measure aspects of how your lungs work, including how much air you can breathe in and out and how effectively air moves through your respiratory system. They may help clinicians evaluate breathing difficulties and certain lung conditions.

Sleep studies record selected body signals during sleep to help assess sleep-related breathing disorders and other sleep concerns. The type of study and monitoring method depend on the clinical indication.

Clear guidance through your diagnostic journey.
Breathing problems and sleep-related symptoms can have different causes. Appropriate diagnostic tests provide useful information to help clinicians decide whether further assessment or treatment is needed.
Understanding the process can help you prepare for your visit. Your healthcare provider will explain the procedure relevant to your particular test.
Depending on the test ordered, you may breathe through a mouthpiece connected to a measuring device. You may be asked to take a deep breath and breathe out in a particular way. Follow the instructions given by the testing team.
Depending on the type of study, sensors may record breathing, oxygen levels, heart rate and other signals while you sleep. Your clinician will explain whether an overnight laboratory study or another monitoring option is appropriate.
