Diffusion Capacity Test

A Diffusion Capacity Test measures how effectively your lungs transfer oxygen from the air you breathe into your bloodstream. During the test, a small amount of a safe, harmless gas is inhaled, and then the amount that remains in the lungs is measured as you breathe out. This helps doctors evaluate the health of your lung tissue and how well your lungs are functioning to oxygenate your blood. It’s useful for diagnosing and monitoring lung conditions like emphysema, fibrosis, or pulmonary vascular diseases. The test is quick, non-invasive, and provides valuable insights into your lung’s gas exchange efficiency.
