Bronchoscopy can be done for tuberculous pleurisy, but it does not always confirm the diagnosis. Bronchoscopy is mainly for the diagnosis of bronchial tract diseases, such as bronchitis, bronchiectasis and bronchial asthma. However, the diagnostic effect for tuberculous pleurisy is not clear, so it has to be evaluated by other tests. There are many tests that can be used as tuberculous pleurisy, including laboratory tests, serum blood immunoassay tuberculin skin test, etc., from which the presence or absence of tubercle bacilli can be analyzed, and it is also possible to find out whether there is any effusion present in the pleural cavity. However, tuberculous pleurisy is similar to tuberculous pyothorax, dry pleurisy and other diseases, which should be differentiated under the guidance of a doctor.
