Doctors use lung diffusion tests to measure how well a person's lungs exchange oxygen and carbon dioxide. The test can detect lung damage and help diagnose lung conditions, including emphysema and pulmonary hypertension.

A doctor may use lung diffusion testing to diagnose asthma. A lung diffusion test is used to examine how your lungs are processing air. Your doctor can use it to either diagnose or monitor a range of lung diseases. Lung diffusion testing measures how well the lungs exchange gases.

Learn more about how lung diffusion tests are performed. A gas diffusion study is also called lung diffusion testing, or diffusing capacity of the lung for carbon monoxide (DLCO). The test can be used to measure health. Lung diffusion capacity assesses how well oxygen gets into the blood from the air you breathe.
For this test, you will breathe in and out through a tube for several.
A doctor will assess a person's risk factors and other symptoms to work out the cause of the abnormal results. A doctor may recommend avoiding particular activities or medication before a lung diffusion test. Lung diffusion tests compare the amount of carbon monoxide in the air you inhale versus the amount in the air you then exhale. In someone with strong, healthy lungs, far less carbon monoxide will be present in the exhaled air than was present in the inhaled air.
