    Signs and tests

    Your health care provider will take a detailed medical history, and will ask many questions to try to find out whether your symptoms relate to certain exposures or times of exposure. The health care provider will also do a physical exam, with special attention to the lungs. Other tests include:

    • Chest x-ray
    • Pulmonary function tests
