Diagnosis of silicosis is based on:
- a detailed occupational history.
- chest x rays will usually show small round opaque areas in chronic silicosis; the round areas are larger in complicated and accelerated silicosis
- bronchoscopy
- lung function tests
It should be noted that the severity of the patient's symptoms does not always correlate with x-ray findings or lung function test results.
