Pleural culture
 
Overview   Risks   Results   

Pleural fluid culture

Alternative names:

culture - pleural fluid

How the test is performed:

A sample of pleural fluid is placed on culture plates containing growth media. When colonies of microorganisms have reached sufficient size, a series of biochemical tests can be performed to identify the presence of specific organisms.

How to prepare for the test:

It is important not to cough, breathe deeply, or move when the fluid sample is being taken. There is no other special preparation for the test.

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:

How the test will feel:

The specimen is obtained by a needle aspiration of the pleural space. The chest is cleansed with antibacterial soap. A needle is placed between the ribs and a small amount of fluid is withdrawn from the chest. There will be pressure and some localized pain associated with the test. A chest X-ray may follow the test to be sure the lung tissue was not affected by the test.

Why the test is performed:

The test is performed when infection of the pleural space is suspected or when an abnormal collection of pleural fluid is noticed by chest X-ray.
