​​

These are tests to diagnose lung/respiratory disorders and measures lung function.

There are a number of diagnostic tests that are done including:

  • Pulmonary function testing (PFT) - diagnostic and therapeutic tests that help identify various aspects of lung disease.
  • Methacholine challenge testing (MCT) - evaluates Airway Hyper Responsiveness (AHR) to help identify the occurrence of asthma
  • Home oxygen assessments - This test is required in order to qualify for oxygen under the Home Oxygen Program. It includes monitoring oxygen levels on room air, a possible arterial blood gas (if oxygen levels low), as well as the possibility of a walking oxygen level test.
  • Spirometry and oximetry testing - measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
  • Asthma exercise testing - also known as exercise-induced asthma (EIA) testing. It includes a combination of several breathing, exercise and cardiology tests which show how the heart and lungs work together during exercise.
Arterial blood gases (ABG) - This test requires collecting a small amount of blood from an artery which determines the level of oxygen, carbon dioxide or pH balance of your blood.
