Lung needle biopsy culture

Alternative names:

culture - lung needle biopsy

How the test is performed:

A needle biopsy of the lung tissue is obtained and sent to the laboratory. The tissue sample will be placed in special media and observed for the growth of organisms. Biochemical reagents may also be used to detect reactions that indicate the presence of certain microorganisms.

How to prepare for the test:

Before a needle biopsy of the lung, a chest x-ray, CT scan of the chest, or bronchoscopy has been performed. A mild sedative may precede the biopsy. You must sign a consent form. It is important to remain as still as possible for the biopsy and to refrain from coughing.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

A lung needle biopsy is preceded by a local injection of anesthetic. You will feel pressure and brief sharp pain when the needle touches the lung.

Why the test is 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.
