Peritoneal Fluid for D/R

Overview:
The Peritoneal Fluid for Diagnosis and Reporting (D/R) test involves obtaining a sample of peritoneal fluid from the abdominal cavity to assess its composition. This test is used to diagnose the cause of fluid accumulation in the peritoneal cavity, which may occur due to infections, malignancies, or other abdominal conditions.

What it detects:
The test helps detect:

Infections (e.g., peritonitis or spontaneous bacterial peritonitis)

Cancer cells (e.g., peritoneal carcinomatosis or metastasis from abdominal malignancies)

Ascitic fluid (commonly seen in liver cirrhosis or heart failure)

Blood or hemorrhage (from trauma or other internal bleeding sources)

The test involves analyzing the appearance, cell count, protein levels, glucose levels, and conducting cultures for any bacteria, fungi, or abnormal cells. The results can help guide treatment decisions, such as antibiotics or chemotherapy.

Who should get it:
This test is recommended for individuals experiencing symptoms of abdominal pain, distension, fever, or nausea, especially if there is a suspicion of an abdominal infection or cancer. It’s commonly performed for patients with conditions like liver disease, cancer, peritonitis, or those with fluid buildup in the abdomen (ascites).

Sample required:
A sample of peritoneal fluid is required. This is typically obtained by paracentesis, which is a procedure where a needle is inserted into the abdominal cavity to collect the fluid.

Fasting requirements:
Fasting is generally not required for this test, though it may be needed before the procedure based on medical instructions.

Processing time:
