Overview   Risks   Results   

Pericardial fluid culture

Alternative names:

culture - pericardial fluid

How the test is performed:

Samples of the fluid are placed in various culture media in the laboratory. The media is observed for the growth of colonies of microorganisms. Certain biochemical tests can identify certain organisms while others require serological tests or tissue culture to identify organisms. The availability of results varies from a few hours to several weeks depending on the type of organism.

How to prepare for the test:

Food and fluid will probably be restricted for several hours before the test. A chest X-ray or ultrasound may precede the test to identify the area of fluid collection.

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:

In some people, a cardiac monitor may be placed prior to the test to monitor for heart disturbances. patches called electrodes will be placed on the chest similar to an ECG. A chest X-ray or ultrasound may precede the test. The skin of the chest will be cleansed with antibacterial soap. A trained physician, often a cardiologist, will obtain the sample. A small needle is inserted into the chest between the ribs into the pericardium (the thin sac that surround the heart) and a small amount of fluid is withdrawn. There will be a sensation of pressure, and some pain as the needle is inserted into the chest. An ECG and chest X-ray may also follow the procedure.

Why the test is performed:

The test is performed when an infection of the heart is suspected or when a pericardial effusion is present.
