Idiopathic Pulmonary Fibrosis Overview

Exams and Tests

The health care provider will perform a physical exam and ask questions about your medical history. Your doctor will ask whether you have been exposed to asbestos.

Patients with idiopathic pulmonary fibrosis have abnormal breath sounds called crackles. Patients with advanced disease may have blue-colored skin ( cyanosis ) around the mouth or in the fingernails due to low oxygen.

Examination of the fingers and toes may show abnormal enlargement of the fingernail bases ( clubbing ).

Tests that help diagnose idiopathic pulmonary fibrosis include the following:

• Bronchoscopy with transbronchial lung biopsy
• Chest CT scan
• Chest x-ray
