Asbestosis Diagnosis

The diagnosis is made based on:

• Reliable history of exposure to asbestos
• Evidence of lung scarring and fibrosis which is based on a physical exam and/or additional tests
• Absence of other causes that may produce similar clinical pictures

Tests used in diagnosis of asbestosis:

• Chest X-ray-changes seen on the exam usually have a distinctive pattern
• CT scan -a type of x-ray that uses a computer to make pictures of structures inside the body. A high resolution CT is more sensitive that a plain x-ray in detecting abnormalities in individuals who were exposed to asbestos.
• Pulmonary function test-a test that measures how well the lungs take in and exhale air. The test can show if the lungs have reduced ability to function properly.
• Oximetry is a noninvasive means to assess oxygen status.
