Bronchoscopy and Bronchoalveloar Lavage.

A bronchoscopy is a procedure that allows a doctor to examine the inside of the lungs, including the bronchi, which are the main pathways into the lungs.

During a bronchoscopy, a doctor inserts a thin tube containing a light and camera into the lungs through the nose or mouth. The doctor can use the findings to diagnose infections, tumors, or diseases in the lungs.

It is a relatively quick and painless procedure, it requires little preparation, and people tend to recover quickly.
