Culture and Sensitivity - Aerobic [Peritoneal/Ascitic Fluid]

A procedure called paracentesis is used to collect peritoneal or ascitic fluid. In this procedure, a needle is carefully inserted through the abdominal wall into the peritoneal cavity. Ultrasound may be used to guide the needle.

This test can diagnose bacterial infections in the peritoneal or ascitic fluid. By identifying the type of bacteria and knowing which antibiotics they are sensitive to, your doctor can choose the most effective treatment for your infection.

A doctor might order this test if you have symptoms of an infection such as abdominal pain, fever, or tenderness. It is also ordered if you have unexplained fluid build-up in the abdomen.

Paracentesis is generally a safe procedure, but there can be risks and complications such as infection, bleeding, and injury to the intestine or bladder.

Usually, no special preparation is needed, but it’s important to follow your doctor’s instructions. Inform your doctor of all medications you are taking.

The peritoneal cavity can be infected by bacteria such as Escherichia coli (E. coli), Streptococcus, or Staphylococcus. Sometimes, fungi or tuberculosis bacteria can cause infections too.

No, this test is specific for bacterial infections. Other tests are needed to diagnose viral, fungal, or parasitic infections.

If bacteria are grown in the culture, it indicates an infection. The sensitivity portion of the test will show which antibiotics are effective against the bacteria. If no bacteria grow, it is likely that there is no bacterial infection in the fluid.

Treatment typically involves antibiotics to fight the infection. In some cases, if there is a large amount of infected fluid in the abdomen, a procedure to drain the fluid may be necessary.

You should consult your primary care doctor who may refer you to a specialist such as an infectious disease specialist or a gastroenterologist, depending on the underlying cause of the infection.

The results of this test will guide your doctor in selecting the most effective antibiotic for treatment, which is crucial for resolving the infection and preventing complications.

Common causes of ascitic fluid accumulation include liver cirrhosis, heart failure, tuberculosis, and cancer. Infection is also a cause and is known as spontaneous bacterial peritonitis when it occurs without an apparent cause.

The Culture and Sensitivity - Aerobic [Peritoneal/Ascitic Fluid] test, physicians are able to accurately diagnose and effectively treat bacterial infections within the peritoneal cavity. The ability to identify the bacteria and understand its antibiotic sensitivity is fundamental for the recovery and well-being of the patient. It is imperative for patients to communicate openly with their doctor and follow the prescribed treatment plan for the best possible outcomes.
