Peritoneal fluid is a liquid that is made in the abdominal cavity to lubricate the surface of the tissue that lines the abdominal wall and pelvic cavity and covers most of the organs in the abdomen. An increased volume of peritoneal fluid is called ascites.

Sampling of peritoneal fluid is generally performed by peritoneocentesis.

Peritoneal Fluid Analysis

The serum-ascites albumin gradient (SAAG) is the most useful index for evaluating peritoneal fluid and can help distinguish ascites caused by portal hypertension (cirrhosis, portal vein thrombosis, Budd-Chiari syndrome, etc.) from other causes of ascites. SAAG is calculated by subtracting the albumin measure of ascitic fluid from the serum value. In portal hypertension, the SAAG is >1.1 g/dL while ascites from other causes shows a SAAG of less than 1.1 g/dL.

Peritoneal fluid microscopy is a useful test in evaluating the cause of ascites. A diagnostic peritoneal lavage (DPL) is considered positive if any of the following are present ^[1] 1. >15 mL gross blood 2. RBCs >100,000/mL 3. WBCs >500/mL 4. Bacteria present on Gram Stain

Bacteria and white blood cells, when present in a patient with a history of ascites (usually due to cirrhosis) is highly suggestive of spontaneous bacterial peritonitis.

BACKGROUND: The controversial results from different studies suggested that leukocyte recruitment mediated by leukotriene B4 (LTB4) and its receptor might improve pathogen clearance, but might also aggravate organ injury during sepsis. The present study was performed to compare the effect of BLT1 li
