To obtain a sample of lung tissue for biopsy, a needle is inserted within the lung and a sample is withdrawn and sent to the laboratory. The laboratory test isolates and identifies organisms that cause infection from the lung specimen. A lung needle biopsy culture is performed when infection of the lung is suspected and sputum or bronchoalveolar lavage cultures have not identified the cause of the infection.
