Peritoneal fluid culture

Definition:

Peritoneal fluid culture is a laboratory test performed on a sample of peritoneal fluid to isolate and identify the presence of microorganisms that cause infection (peritonitis).

Peritoneal fluid is the fluid from the peritoneal cavity, a space between two membranes lining the abdominal cavity.

Alternative Names:

Culture - peritoneal fluid

How the test is performed:

The test is performed by paracentesis, a needle aspiration of the peritoneal cavity. A sample of fluid is sent to the laboratory for gram stain and culture preparation. The sample is examined regularly for the growth of microorganisms.

How to prepare for the test:

Empty your bladder prior to the paracentesis procedure.

How the test will feel:

A small area in your abdomen will be cleaned with an antiseptic. You will also receive local anesthesia and may feel a stinging sensation from the shot. You will then feel pressure as the needle is inserted. If a large amount of fluid is withdrawn, you may have a feeling of dizziness or light-headedness.

Why the test is performed:

The test is done to find out if there is an infection in the peritoneal space (peritonitis).
