Diagnosis of Interstitial Lung Disease
To accurately diagnose your lung condition, your physician will perform a series of tests and go over some questions about your medical history, health, wellness and any smoking habits have or have had in the past.

Since interstitial lung disease includes many lung diseases, the tests your physician orders may include many of the following:

Chest x-ray
CT scan
Blood-gas analysis
Pulmonary function test
Bronchoscopy

The objective of diagnosis is to quickly identify the cause of your interstitial lung disease so that treatment may be administered to slow the progression of your scarring.
