Lung needle biopsy culture

Lung needle biopsy culture is a laboratory test that examines a piece of lung tissue to look for the cause of an infection.

Alternative Names

Culture - lung needle biopsy

Why is the Test Performed?

A lung needle biopsy culture is performed when infection of the lung is suspected and sputum or bronchoalveolar lavage (see Bronchoscopy with lavage "BAL") cultures have not identified the cause of the infection.

How is the Test Performed?

After a piece of lung tissue is taken from a patient's lung (a biopsy), the tissue is sent to a laboratory. The laboratory technician will place the tissue sample in a special substance that promotes growth. This can help identify the cause of illness or infection.

Preparation for the Test

See lung needle biopsy.

The culture is done in a lab. You do not need to prepare for this.

Normal Results for Lung needle biopsy culture
