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 abdominal tap, 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 before your abdominal tap 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 If a large amount of fluid is withdrawn, you may feel dizzy or light-headed.
