What is Diffusion Capacity (DLCO) testing?
Diffusion capacity (DLCO) is a clinically useful test that provides a quantitative measure of gas transfer from the lungs to the blood. It complements spirometry in evaluating and managing patients with cardiac and/or respiratory disease.
Why DLCO is important in lung disease diagnosis and management:
- Helps differentiate between obstructive and restrictive lung patterns.
- Detects early changes in gas exchange, even when spirometry appears normal.
- Assists in evaluating interstitial lung diseases, such as pulmonary fibrosis.
- Useful for monitoring disease progression or response to treatment.
