Find a Lung (Pulmonary) Function Test Near You

Breathing problems can significantly impact your daily life, making it essential to assess your lung health if you’re experiencing symptoms like shortness of breath, chronic cough, or wheezing. A Lung (Pulmonary) Function Test helps evaluate how well your lungs are working by measuring airflow, lung capacity, and oxygen exchange. Whether you have asthma, COPD, or another respiratory condition, finding a reliable lung function test near you can provide crucial insights into your lung health..

What Is a Lung (Pulmonary) Function Test?

A Lung (Pulmonary) Function Test is a non-invasive diagnostic assessment that measures different aspects of lung function, including how much air you can inhale and exhale, how efficiently your lungs transfer oxygen into your bloodstream, and whether there is any obstruction or restriction in airflow. These tests help diagnose and monitor conditions such as asthma, chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and other respiratory disorders.

The test typically involves breathing into a specialised device, such as a spirometer, to measure airflow and lung capacity. Additional tests like gas diffusion studies and body plethysmography may be conducted depending on the patient's needs.

Benefits of a Lung (Pulmonary) Function Test

  • Early Detection of Lung Conditions – Helps identify issues such as asthma, COPD, or lung disease before symptoms worsen.
  • Monitors Disease Progression – Tracks lung health over time for individuals with chronic respiratory conditions.
  • Optimises Treatment Plans – Provides essential data to tailor medication and therapy for improved respiratory function.
  • Assesses Lung Function for Surgery – Ensures patients are fit for procedures requiring anaesthesia.
  • Identifies the Impact of Environmental Factors – Measures the effects of pollution, smoking, or occupational hazards on lung health.

Who Might Need a Lung (Pulmonary) Function Test?

A Lung (Pulmonary) Function Test is beneficial for individuals experiencing:

  • Chronic cough, wheezing, or shortness of breath.
  • Frequent respiratory infections or difficulty breathing.
  • Diagnosed lung conditions like asthma or COPD.
  • Exposure to environmental pollutants or occupational lung hazards.
  • A history of smoking and concerns about lung health.
  • Preoperative assessments before major surgery.

If you have ongoing respiratory symptoms, a lung function test can provide valuable insights into your lung health. Always consult a healthcare professional to determine if testing is appropriate for your condition.

What to Expect from a Lung (Pulmonary) Function Test

  1. Pre-Test Preparation – You may be advised to avoid smoking, caffeine, and heavy meals before the test.
  2. Spirometry Test – You will breathe into a spirometer, which measures airflow and lung capacity.
  3. Gas Diffusion Testing – This assesses how efficiently oxygen moves from the lungs into the bloodstream.
  4. Body Plethysmography (if required) – Measures lung volume and airway resistance for a detailed assessment.
  5. Results & Consultation – A healthcare provider will explain your results and discuss next steps if any abnormalities are found.
