Peritoneal fluid culture
What is Peritoneal Fluid Culture?
A Peritoneal Fluid Culture is used to detect and identify infectious agents such as bacteria, fungi, and parasites that have infected the peritoneal lining of the abdomen. The peritoneum is a thin membrane that lines the inside of the abdominal cavity and covers the organs found there. By collecting a sample of this fluid and culturing it, any potentially dangerous bugs can be identified.
Preparation
Before getting a Peritoneal Fluid Culture, the doctor may ask a few questions about your medical history, such as whether you have any other illnesses, have traveled recently, and/or been exposed to certain infectious agents. The doctor may also do a physical exam to check for signs of infection in the abdomen.
Procedure
During the Peritoneal Fluid Culture procedure, you will lie down on an x-ray table and the doctor will insert a needle into your abdomen to collect a sample of the fluid. The needle is then sent to a lab to be tested for signs of infection, and the results are analyzed to determine what type of organism is present.
Types
There are several different types of Peritoneal Fluid Cultures that may be used to identify infections:
- Bacterial cultures: These are most often used to detect the presence of bacteria.
- Fungal cultures: Used to detect the presence of fungi.
- Parasitic cultures: Used to detect the presence of parasites.
- Mycobacteria cultures: Used to detect the presence of mycobacteria, such as the bacteria that cause tuberculosis.
Risks
Although Peritoneal Fluid Cultures are generally considered to be a safe procedure, there is always the possibility of complications. There is a small risk of infection at the site of needle insertion, as well as the risk of a reaction to the local anesthetic used before the procedure. Additionally, there is the risk of an allergic reaction to the culture media used in the lab.
Why Is It Done?
Peritoneal Fluid Culture is performed when a doctor suspects that an infection is present in the abdomen. This may be due to symptoms such as fever, abdominal pain, nausea and vomiting. Additionally, it can be used to monitor patients with chronic conditions that are at risk for infections.
When is It Done?
Your doctor may recommend a Peritoneal Fluid Culture if they suspect that an infection is present in your abdomen. It can also be used to monitor patients with chronic conditions, such as HIV, cancer, or kidney failure. Additionally, it can be used to rule out infection in cases such as appendicitis.
